Gold is perhaps the most classic metal for making wedding rings; about 90% of all newlyweds choose it. But every year platinum begins to gain momentum. Let's figure out why this happens, why platinum is better than white gold when choosing wedding rings, if outwardly these metals are almost impossible to distinguish
White gold in wedding rings
You should be aware that the gold used in jewelry is not a pure precious metal, but an alloy. Due to the softness and fragility of pure gold, the production of jewelry is impossible without adding a fairly high percentage of other metals to the alloy - copper, silver, nickel, etc. In particular, 750-carat gold will contain 25% of other metals, and 585-carat gold will contain 41.5%. The lower the gold purity, the higher the percentage of other metals in the alloy.
Platinum, on the other hand, is a fairly strong metal, so platinum rings are composed almost entirely of the precious metal. For example, the most common ring of 950 standard contains 95% pure precious metal and only 5% impurities of other metals, which give the alloy strength and durability to the product.
Which sparkles better, white gold or platinum?
You may be disappointed, but the shine of the two wedding rings - white gold and platinum - is almost impossible to distinguish from the outside. This is because every piece of jewelry is plated with rhodium after manufacturing, it is this metal that gives white gold and platinum jewelry their unique radiant shine. Over time, they may fade with daily wear, but rhodium plating can restore their original shine.
Why is platinum more expensive than gold?
In nature, platinum is a fairly rare element. To extract one ounce of platinum, it is necessary to process an average of 10 tons of ore. By comparison, an ounce of gold can be extracted from just 3 tons of gold ore. The cost of platinum mining is on average three times higher than gold mining.
Jewelry manufacturers' demand for platinum is growing every year. This is confirmed by the fact that even in Ukraine every year the number of couples choosing platinum wedding rings grows exponentially.
Platinum is a very difficult metal to process. It melts at much higher temperatures than gold and requires separate professional equipment and the skill of jewelers.
Despite the fact that the market value of platinum may not differ much from gold, in a piece of jewelry this difference will be much more noticeable, since about 30% of the cost of a piece of jewelry is the complex work of a jeweler creating jewelry from platinum.
Gold and platinum in jewelry
Now about the most pleasant thing - about the sensations when choosing platinum wedding rings. Due to the fact that this metal is much heavier and denser than gold, products of the same volume made of platinum weigh almost twice as much as similar gold ones. Therefore, when you try on a platinum wedding ring, you will feel a pleasant heaviness; most couples choose this metal precisely for this unique feeling of weight and value, which they transmit to their relationship.
Because platinum is stronger, platinum wedding rings are less prone to scratches than gold ones. This is also a strong practical argument for platinum wedding rings that will be worn every day.
Each couple must decide for themselves what metal they want their wedding rings to be. The specialists of the ZBird Jewelery jewelry store can only help in choosing, advise and promise to produce any of the designs you choose in any of the selected metals. It is not so important whether your wedding rings are gold or platinum, it is important that they add value to your feelings and make your family strong and happy.
Choosing wedding rings is perhaps one of the most important tasks for newlyweds when preparing for their wedding. Today we'll look at some of the top trends in engagement ring design that are shaping this season's wedding jewelry fashion and determining what the most beautiful engagement rings will look like this year.

White gold and platinum - what is their difference?
Modern technologies for processing metal and precious stones allow designers to create breathtaking masterpieces of jewelry. There is plenty of room for creativity - yellow, red, white gold, silver and even platinum
In order for you, as a buyer, to make the right choice, you need to have some knowledge about precious metals. After all, 90% of the cost of jewelry depends on what metal it is cast from. Today Zlato.ua will talk about the main differences between white gold and platinum.
Platinum has long been called a “men’s metal”, because initially it was used to make massive and rough signet rings or link bracelets, and later into cufflinks and heavy chains. And although modern trends are trying to blur these stereotypes, most of us still associate platinum with men's jewelry.
№1
First of all, platinum is a pure metal, which is included in the D.I. table. Mendeleev and has a silver-gray tint. It is typically 95-99% pure and may contain only a few percent natural impurities.
White gold is an alloy that consists of gold, nickel, silver, platinum or palladium. Since nickel can cause allergic reactions, palladium has been actively used instead.
№2
Unlike white gold, platinum is hypoallergenic. Gold jewelry can cause various skin irritations and rashes. This often depends on what kind of ligature is included in its composition and the individual reaction of the human body.
№3
Gold is a soft and ductile metal. Platinum is very durable and wear-resistant. White gold jewelry is lighter in weight, but may become deformed. Not by themselves, of course - because of blows, falls, etc.
№4
Platinum is naturally silvery-white in color.
For added shine, platinum jewelry is sometimes coated with a layer of rhodium. Gold is yellow. Its white tint is given by impurities of silver, nickel, platinum or palladium. White gold jewelry is also coated with a layer of rhodium to protect it from unwanted damage and enhance the noble white hue.
Rhodium itself is very similar in properties to platinum: it is a durable, wear-resistant, white metal. Unfortunately, over time, the rhodium layer wears off and the jewelry becomes a little dull. Don’t worry if after a few years of wear, your jewelry will lose its “face” a little. All you need to do is restore the rhodium plating in a jewelry workshop. Fortunately, this is a very simple and quick procedure.
№5
An important difference between platinum and white gold is the price. Platinum is several times more expensive than white gold. Although in the last century it was even cheaper than silver. Due to its refractoriness, platinum was rarely used to create jewelry. Not all factories, not to mention medium and small jewelry workshops, had the technical capacity to melt down platinum.
By the way, do you know the origin of the word “Platinum”? In the 16th century, when Spanish conquistadors were actively mining for gold, workers constantly encountered gray impurities in the yellow metal. “Spoiled” gold could not be cleared of gray grains and the miners called it rotten. The impurity itself, due to its external resemblance to silver, began to be called platinum, that is. "silver". After all, translated from Spanish, plata means silver. This is what rags to riches means 
White gold and platinum samples
- Platinum comes in 950, 900 and 850 samples. This means that it contains 95%, 90% and, respectively, 85% pure platinum. The rest is made up of impurities.
- Gold comes in 750, 585 and 375 samples. Typically, a higher percentage of alloy is added to the gold alloy to add strength. Working with gold in its pure form is a rather labor-intensive process, and jewelry made from pure metal is very fragile, quickly deforms and is more sensitive to external factors. You can only find pure gold in bars.
Platinum and gold hallmarks differ in form and content
In appearance, platinum and white gold are quite similar, but in fact there is a whole chasm opening up between these metals. Platinum is a metal that is mined directly from the bowels of the earth, and white gold is the result of human imagination: mixing gold and alloy. It is almost impossible to visually distinguish jewelry made from white gold and platinum, so be sure to pay attention to the hallmark and hallmark.

Platinum or white gold, what are the differences and similarities between noble metals
The fact that platinum and gold are used in jewelry is not a secret for many, but why products made from this metal are valued more than gold is a big discovery for many. In practice, it is not difficult to figure out whether platinum or white gold is more valuable; it is enough to understand the similarities and differences between these two jewelry metals.
general characteristics
In order to understand what platinum is and what white gold is, you need to take a short excursion into history. The fact that gold has been used by mankind has long been known for certain. Archaeological excavations confirm that humanity has not changed at all in its attitude towards gold - the yellow metal has always been held in high esteem.
But the attitude towards platinum was not always favorable. During the conquest of America, the Spanish conquistadors considered platinum to be a harmful or “rotten” metal that affected gold.
In fact, at that time, technology did not allow the separation of platinum from alloys and other metals, so it turns out that the metal was undervalued for a long time.
What is platinum
Among natural minerals, platinum is a very rare metal. But this was not the only reason for its popularity and value. Excellent physical and chemical properties are used in many industries and, most importantly, in jewelry.
To create jewelry, platinum is used as an independent metal and as an additional metal, designed to highlight the beauty of gold. According to its properties, the metal has good plasticity - it is easy to work with. Well, as for the appearance, the exquisite cold shine has always attracted the eye.
What does platinum look like?
The durability of platinum jewelry is much higher than the durability of gold jewelry. This is an expensive metal; as you know, the annual production of platinum is several times less than gold. It also has high anti-corrosion properties - it does not come into contact with oxygen, does not oxidize, and does not irritate the skin. It is not for nothing that the kings of France had one of the largest collections of jewelry made from this metal.
What is white gold
Unlike platinum, white silver is more widely distributed. This is one of the popular jewelry alloys for creating jewelry today. But despite its popularity, when comparing platinum and white gold, you need to understand that white gold is an alloy, and if so, the difference is obvious. White gold does not occur in nature; it is obtained by combining several metals in different proportions.
The main component of the alloy is gold, otherwise the alloy would not have such a sonorous name, but the remaining components are metals that are absolutely not related to precious metals - copper, zinc, nickel. And even though silver is present in the recipe, it is not worth calling white gold a noble metal in comparison with platinum.
In addition, when comparing the effects of these two metals on the human body, it should be noted that white gold is prone to oxidation, and its constituent zinc and nickel cause an allergic reaction.
Comparative characteristics and differences
To understand more deeply which metal is more valuable, platinum or white gold, you need to consider in detail all the characteristics, from weight and melting point to methods of caring for jewelry.
Compound
The composition of the alloy says a lot about the value of the metal in jewelry. The value of a product has always been higher, the more pure precious metal it contains.
Platinum is a natural metal mined from the earth. It is present in products in the form of pure metal as individual elements and is part of alloys. The most commonly used metal is the highest 950 standard, which means that the platinum alloy contains 95% pure metal.
White gold in the metals and alloys brand has several grades. In jewelry, it is used in samples from 385 to 750. This means that the alloy contains from 38.5% to 75% pure gold. The remaining mass parts are nickel, silver, palladium or platinum.
Therefore, it is not difficult to conclude that it is more expensive; pure metal is always valued.
Strength and weight
The mechanical properties of jewelry are influenced by the metal they are made of. The density of platinum is 21.5 grams/cm3, the density of the same volume of gold is less, only 19.3 grams/cm3. As part of the alloy, the density is even lower; for 583 white gold it ranges from 12.8 grams/cm3 to 14.7 grams/cm3. So the difference between platinum and white gold is obvious - the density of the alloy is almost 50% lower.
Platinum density – 21.5 grams/cm3
The mechanical qualities of metals are also different; the white alloy has more pronounced ductility and is easier to process under pressure. And platinum is characterized by strength and high load resistance. Jewelry made from the alloy is easily deformed, which cannot be said about platinum. Rings, bracelets, and watch cases made of gold require additional polishing 1-2 times a year, but platinum is not prone to damage to the surface, scratches are practically invisible on it.
External features
The difference between the alloy of gold and platinum is also visible in external features.
Platinum has a natural white color; in nuggets it is matte, but in products where mechanical processing and polishing were carried out it is glossy, one might even say arrogantly arrogant.
White gold is an alloy, and its appearance depends on how many specific parts are in the composition of gold itself, and how much zinc, copper, silver and nickel. The color range ranges from a cool shade of yellow to a pronounced shine with a yellow tint.
It is almost impossible to see white gold in jewelry - the entire surface is covered with rhodium - the surface acquires gloss and additional protection from mechanical damage. But platinum does not require additional protection.
Samples and quality
In jewelry, the hallmarks of platinum and pure gold differ greatly. The difference between platinum is that the most common hallmarks are 950, 900 and 850. If you take into account what hallmark is on the product, you can conclude that the jewelry consists of almost metal without impurities.
For white gold, the highest standard is 750, but this is the highest standard, and so, usually the samples of such metal correspond to 385, 500, 585. It is not difficult to guess the difference; the metal contains from 61 to 41 percent of impurities of other metals.
Production
Platinum and white gold also have different origins. Platinum is usually mined in mines and quarries located close to gold mines. It so happened that this white metal is mined as a mineral in the form of nuggets. Further processing involves cleaning, smelting and machining.
Platinum mining site
White gold is created through the melting process of several metals. Raw materials for the production of jewelry metal are mined in different places, after which the ore is purified and the metal is smelted. And white gold is melted directly at precious metals factories.
As you can see, white gold and platinum have differences in the mining process and production of jewelry metal.
Effect on skin
Unlike platinum, white gold can cause severe allergies in those who constantly wear gold items. One of the most prominent allergens in the alloy is nickel, which is why since 2000, according to European Union directives, European jewelers have been prohibited from using it in white gold as part of the alloy.
Platinum, as a noble metal, is in itself safe for health. It does not cause allergies; there is no nickel in platinum products.
Pros and cons of white gold and platinum
When assessing whether white gold or platinum is more valuable, you need to take into account that both metals are classified as precious metals. But when choosing jewelry made of platinum, you should think about the fact that its price, with the same weight as gold, will be higher.
Additionally, white gold and platinum have different densities and strengths. White metal does not require additional care efforts; it does not need to be taken to a workshop for polishing. On the other hand, white gold is a more common and more popular material.
More gold products are produced, and compared to platinum, such products are cheaper.
But as for investing in jewelry, white gold and platinum have different values - there is a fashion for gold, white gold is popular today, red or green may be tomorrow. But platinum is always in price.
Although, if you ask a woman which jewelry to choose, she will probably say that both white gold and platinum will suit each other perfectly in one ensemble, and they will also look good separately.

Is white gold and platinum the same thing?
articles:
- Pros of platinum
- Platinum and white gold
Among jewelers, platinum is called the queen of all precious metals, but people did not immediately understand its value. Spanish conquistadors who mined gold back in the 16th century found yellow metal with gray impurities. There was no way to clean such gold from such grains and the miners began to call it rotten.
The impurity itself, which spoils the metal, began to be called platinum, i.e., due to its external resemblance to silver. “silver”, because in translation from Spanish plata means silver. Platinum melted very poorly, which is why it could not be used for a very long time, and therefore its cost was half that of silver.
Some people believe that white gold and platinum are the same thing, but this opinion is wrong.
If white gold is an alloy of gold with silver, nickel or some other metals, then platinum is a pure metal. The French king Louis XVI himself considered platinum the only royal metal and owned a fairly large collection of jewelry made from it. But still, the question of which is better: expensive and sought-after platinum or white gold is quite complicated, because each metal has its own advantages and disadvantages.
Pros of platinum
Platinum, used in jewelry, is a white, fairly plastic and shiny material that tolerates the use of chemicals well and also has anti-corrosion properties. It can be found infrequently in the natural sphere, but this is not the only reason for its high price.
It has become one of the popular materials among European jewelry companies, because it lasts well for a long time, is more resistant to wear, and, moreover, does not deform under pressure.
In general, this platinum is the most durable jewelry metal, which allows it to be used not only in jewelry, but also in technology.
Speaking about how white gold differs from more expensive and rare platinum, it should be noted that alloys with white gold have much worse properties of endurance and durability.
Nowadays, platinum products are an indicator of prosperity and confidence in the future, because they can only be purchased by wealthy people, and this fact eliminates possible questions about what is more expensive: platinum or white gold containing foreign impurities. Almost all platinum on the market has a high purity (purity of the metal), and is therefore safe for allergy sufferers.
And if in Japan and Western countries platinum is already quite well known as a beautiful and durable material, then in Russia the buyer is almost not familiar with it, in contrast to how widespread white gold is. Only in the last few decades has it begun to occupy a good position in the market.
This is also due to white gold, which has become popular relatively recently. The fashion for products made from this material paved the way for platinum jewelry.
The discreet appearance and excellent performance attract buyers, symbolizing durability and long service life.
The advantages of platinum are clear, but the price gets in the way of the desired acquisition. The average platinum jewelry costs from 3500 to 4500 per gram of metal, which depends on the supplier.
White gold jewelry can be a cheap alternative, because depending on the sample, its price can be 2500-4000 rubles per gram. Because of these nuances, the choice of metal depends only on the personal preferences of the buyer and his well-being.
Jewelry made of any metal will be a good investment, especially since if you have a white gold item, then caring for platinum will be no different.
Due to the strength and durability of platinum, it has carved a niche in the field of jewelry making. This metal is especially good for framing precious stones; in its framing, stones are protected from damage and chips. But platinum also has another task - to emphasize the beauty and brilliance of diamonds, to reveal their inner beauty, and to visually enlarge the stones used. The transparency and depth of the stone can only be emphasized by a light-colored frame, which is why they were previously mounted in silver.
Platinum and white gold
The most important advantage and difference of platinum is its nobleness; white gold is an alloy of ordinary yellow metal with silver/nickel/platinum/palladium.
White gold in the past was most often mixed with nickel, but has now begun to be actively replaced by palladium, due to the discovery of the allergic properties of nickel.
For some buyers, this creates restrictions on the use of white gold, while platinum is a completely hypoallergenic material, not as hazardous to health as white gold.
Unlike gold, platinum products are almost always “pure” 950, and white gold is most often 750. The hallmark of these two metals is also different: platinum can have the 850th, 900th or 950th hallmark, white gold - the 500th, 585th or 750th hallmark.
Gold is in the leading position in terms of softness, while platinum occupies the opposite position and is famous for its strength and long service life. The main difference between platinum and white gold is that, despite all its strength indicators, platinum can be reshaped quite well, which makes it possible to make complex and strong structures from it.
This ring is made of white gold.
Platinum is a naturally white or light-colored metal, while white gold has a unique hue depending on the composition of the alloy.
To further whiten gold, it is often additionally plated with rhodium, which has properties similar to platinum. Rhodium gives gold additional resistance to wear and damage, but gradually the rhodium begins to wear off and the appearance of the product deteriorates.
To look good, platinum does not need an additional layer of rhodium, because its properties and appearance make it possible to do without impurities.
Platinum has a higher value than white gold. Previously, it cost mere pennies due to its unknown properties and complex processing process, but after its study it became one of the most expensive metals in the world.
Platinum and white gold are quite similar, but there is actually a big difference between them.
Platinum is a metal mined directly from the earth, while white gold is the result of mixing gold and one of the metals (silver, nickel, platinum or palladium).
The noble metal is absolutely hypoallergenic and safe for people with hypersensitivity to materials, while white gold can cause severe allergies due to the content of another metal in the alloy (most often nickel causes allergies).
Platinum has a minimum of 850 and a maximum of 950, while the minimum fineness of gold for jewelry is 500 and the maximum is 750. Due to its properties and features, silver metal weighs much more than white gold and has a more attractive, natural appearance.
The white color of the precious metal matches diamonds and other light-colored precious stones; white gold can have different shades depending on the metal used.
And because of this apparent similarity, it is necessary to know how platinum differs from the similar, but less expensive white gold.
It is worth remembering that to improve its properties and service life, white gold is rhodium-plated; a platinum product can also be plated with rhodium, but only to update the appearance, because over time even such a metal tarnishes. Due to all the above nuances, platinum is more expensive than white gold and is in the premium segment of precious metals.

Difference between platinum and white gold
You can spend a lot of time looking for a stylish and elegant piece of jewelry that will highlight the individuality of its owner. Silver, platinum, yellow and white gold What should you choose from this noble and very attractive assortment? It is especially difficult to decide when choosing between white gold and platinum, because it seems that they are very similar. But this is not true at all!
articles
Platinum is a rare noble metal of a beautiful silver-white hue, an element of the D.I. table. Mendeleev.
White gold is an alloy consisting of gold and other components (nickel, platinum, silver, palladium) that can color it white.
Comparison
The main difference, of course, is that platinum itself is a noble metal, while white gold is an alloy of traditional yellow gold with silver, nickel, platinum or palladium.
True, until recently, nickel, which is widely used, has increasingly begun to be actively replaced by palladium, since it was discovered that nickel often causes allergic reactions.
So, a piece of white gold may contribute to skin irritation, depending on the metal alloy the jeweler used and how sensitive you are to it. But platinum is absolutely hypoallergenic.
14k white gold
Platinum products, unlike gold ones, are made almost entirely from this precious metal - the platinum content in the alloy averages 95%. Jewelry made of 750-carat white gold contains 75% gold and 25% of other metals listed above, which gives the product a white tint. By the way, the hallmark of products made of platinum and gold is also different: platinum is 850, 900, 950, gold - 500, 585, 750.
Gold is one of the softest metals, while platinum is particularly dense, durable, and wear-resistant. Platinum is also heavier in weight than gold. But, interestingly, platinum is a very ductile metal. Although gold is deformed more easily than platinum, which is much more practical to wear.
Platinum is a naturally white, light metal, while white gold, depending on the purity and type of alloy (whether it is more present in the composition of palladium, silver or the not so popular nickel), has a gray, brownish or grayish-yellowish tint.
To give a white gold product shine, special whiteness and additional hardness, it is often coated with rhodium, a rare noble (and very fragile, so it is used only for coating) silver-white metal, similar in properties to platinum.
Rhodium has the attractive properties of not tarnishing or changing color even over time, and is less likely to scratch than soft gold. The only disadvantage of rhodium plating is that it gradually wears out and the white gold product begins to turn yellow. Therefore, after a few years, it is advisable to “renew” the rhodium plating in a jewelry workshop.
Platinum does not require additional coating to give the product a white color: it already has a silvery-white tint. But for shine, platinum is sometimes also coated with a layer of rhodium, since it can quickly fade.
Another difference between platinum and white gold is cost. Moreover, surprisingly, just a few centuries ago platinum, which was not used at that time because of its refractoriness, was valued at half the price of silver. Today, a ring made of platinum will cost more than a similar product made of white gold.

How is white gold different from platinum?
It can be difficult to find elegant jewelry that would highlight a woman’s individual features; you can spend a lot of time searching.
What to choose: silver, gold or platinum jewelry? It is most difficult to make a choice among products made of white gold and platinum. Jewelry made from white metals is characterized by sophistication and soft shine. They are suitable for both parties and everyday life.
There is an opinion about the identity of these metals. But this is absolutely not true. What are the differences between them?
Features of platinum
- Platinum is characterized by special density and strength . This metal is heavier than gold and is more practical to wear.
- Platinum does not require additional coating to give the product a white color. The shine is sometimes created with rhodium, as the precious metal can tarnish.
- Platinum excels in strength and durability. Despite these qualities, it changes shape well, and complex products can be made from it. This noble metal also weighs more than white gold.
- The metal has sufficient ductility, it is not harmed by chemical reagents, it is not afraid of corrosion, does not oxidize when heated, and has higher electrical conductivity. Rarely found in nature, which explains the high price of platinum. It is also popular because it lasts a long time, is resistant to wear, and does not deform. Platinum is considered the most durable metal and is used not only in the manufacture of jewelry, but also in technology. In comparison, white gold is not as durable and hardy.
- Platinum is used in various fields: electronics and technology, medicine and coinage.
- The downside of platinum is the inability to change the ring size; with gold jewelry this can be done easily.
Features of white gold
- Gold is a soft metal; it leads in softness and is more susceptible to damage.
- White gold, depending on the alloy, can have different shades - from gray to yellowish. To add shine, whiteness and hardness, it is plated with rhodium. It is a rare, noble silvery-white metal that is so fragile that it can only be used for plating. Rhodium does not tarnish, does not change color, and leaves almost no scratches. The only drawback of such a coating is its ability to wear off over time, and yellowness appears on the product. It is recommended to have the coating renewed by a jeweler after several years.
Price
The next difference is the cost of white gold and platinum. Today, platinum is considered the queen of precious metals. Some time ago, platinum was not used. Conquistadors from Spain, who discovered the American continent and mined gold, encountered pieces of yellow metal with gray impurities.
It was impossible to extract these grains from such gold; they began to call the metal rotten. The impurity was called platinum (translated from Spanish as rotten silver). The lack of use of platinum was explained by its refractoriness; silver was twice as expensive.
Now platinum jewelry costs three times more than white gold jewelry.
The effect of precious metals on the skin
- Nickel added to white gold can irritate the skin (nickel has been replaced by palladium). Many countries began to abandon nickel.
- There is no allergy from platinum.
Try
If people want to buy jewelry that will become heirlooms, then they should choose platinum. The presence of platinum products determines the status and well-being of a person.
- The platinum on the market is distinguished by its high 950 standard (purity of the metal).
- For white gold, the minimum standard is 500 and the maximum is 750.
In Western countries, platinum has long been in demand; in Russia, little is known about this beautiful and durable material. Over the past few decades, it has become popular in the precious metals market. This became possible due to the fashion for white gold.
Platinum is very suitable for framing a precious stone; it is protected from damage. Another purpose of using platinum is to emphasize the beauty of diamonds and visually enlarge the stones used.
White gold, depending on the composition of the alloy, can have different shades, it still remains popular and more affordable.

Distinctive features of platinum and white gold
Gold jewelry has always been, is and will be held in high esteem, and all thanks to the beauty, strength and durability of this metal. The jewelry industry uses gold alloys with different shades. The most popular among consumers are red, yellow and white gold. As for the latter alloy, it is confused with another precious metal - platinum. What is the difference between platinum and white gold? In fact, there are many differences between these two metals.
White gold and platinum rings
Differences
Platinum is rightfully considered the “queen of precious metals,” but its value has only recently been recognized. Thus, in the sixteenth century, Spanish gold miners often looked for an unusual metal that in many ways resembled gold, but at the same time had gray inclusions.
However, it could not be cleared of gray impurities, which is why such “gold” was called “rotten.” The name "platinum" comes from the Spanish word "plato", which translates as silver.
However, the discoverers of this metal faced a problem - attempts to melt it ended in failure, which is why platinum was immediately classified as a low-quality metal.
Platinum, unlike silver and gold, has never been used as money. This metal was used to make coins that were not intended for use.
As for the differences between platinum and white gold, there are many:
- White gold is not a special type of metal, as many people believe, but only an alloy of gold with a ligature. This alloy, which looks like platinum, is obtained by combining gold with a white alloy (impurities) - silver, palladium, nickel and platinum. Also, jewelry made from this metal is coated with rhodium, which gives the products a sophisticated look. White gold is graded according to the standard metric system. In most cases, such a metal has a purity of 585, but gold with a purity of 750 is also found in the jewelry industry. As for platinum, its silver-gray hue with shine is natural, while gold is given this color by the composition of the alloy.
- Pure gold is soft, which explains its instability to deformation. As for platinum, this metal, even in its pure form, is characterized by excellent wear resistance and strength. In addition, platinum does not react with other chemical elements and does not oxidize. All these qualities make it possible to use platinum in its pure form (950 fineness) for the purpose of making jewelry. Gold used in the jewelry industry is never used in its pure form, due to its softness and tendency to deform.
- Platinum, in comparison with gold, is characterized by better wear resistance. Jewelry made from this metal can maintain its impeccable appearance for decades, while white gold can tarnish and even turn yellow. The latter occurs due to the abrasion of the rhodium coating. Platinum has an attractive appearance throughout its entire service life, which cannot be said about gold.
- White gold causes allergies in some people, and this is all due to the palladium content in its alloy. Platinum is a hypoallergenic metal that, when worn constantly in the form of jewelry, does not cause any negative consequences.
- Platinum is an elite metal that is 3 times more expensive than white gold, and jewelry made from it emphasizes the well-being of its owner. White gold products are affordable to a wider audience in terms of price. Thus, an ounce of platinum is $300 more expensive than an ounce of gold.
- In nature, platinum is found 30 times less frequently than gold. So, to extract an ounce of this metal, it is necessary to process 10 tons of ore, while three tons are enough to extract the same amount of gold. Because of this, the demand for platinum exceeds supply many times over, which explains the high cost of the metal.
White gold and platinum samples
It is not easy to distinguish platinum from white gold. This is what scammers take advantage of, offering the buyer “platinum,” which actually turns out to be white gold, the price of which is 2-3 times lower than that of platinum.
In addition, this metal is also replaced by silver and sold to customers at the price of platinum. Every person should know that platinum, due to its high cost, is not used for making large jewelry.
Therefore, if a seller offers to buy a heavy ring made of platinum, then the product is most likely a fake.
Platinum is sold only in elite jewelry stores that have been present on the relevant market for many years and have an impeccable reputation. If you are not sure of the authenticity of the product, it is recommended to take it for examination, because only an assessment by an expert can guarantee one hundred percent authenticity of the metal.

What is the difference between white gold and platinum?
Jewelry gold is not gold as a chemical element, Aurum metal. It is always an alloy of pure gold with copper, silver, nickel, platinum or palladium, depending on the specific alloy.
This is due to the physical properties of gold, which is actually so soft and tiny that even 750-karat gold products (a 75% alloy of gold and other metals to give gold strength) are noticeably inferior in reliability and wear resistance to classic 585-karat products ( 58.5% pure gold in the alloy).
Properties of platinum and jewelry made from it
The percentage of pure platinum in jewelry alloy is significantly higher. In jewelry, 950 platinum is most often used (95% of the precious metal in the alloy), but there are also 900 and 850 platinum (90% and 85% of the metal, respectively).
Platinum is quite strong, weighs significantly more than gold, it is generally one of the heaviest metals, and therefore it gives a pleasant heaviness to a product, for example, a wedding ring.

Gold and platinum in jewelry production
The significant difference between platinum and gold, especially for jewelers, is that platinum melts at much higher temperatures. The melting point of platinum is 1768°C (gold is 1064°C), so the production of platinum products requires separate equipment, as well as special skill to create sophisticated jewelry from such a durable metal.
What is the difference between white gold and platinum in price?
Both metals, gold and platinum, are investment instruments; their current prices are determined by the market. But it is worth noting that all investors at different times used precious metals as a reliable tool for preserving assets in times of crisis.
Platinum has traditionally cost slightly more than gold, while the cost of identical jewelry made of platinum and gold can differ significantly in favor of platinum. The reason is precisely the complexity of producing platinum jewelry.
This year, the market value of platinum has fallen below the price of gold. According to financial analysts, the situation will probably soon stabilize and return to previous levels. Therefore, now is a good time to invest in platinum.
By the way, investment is one of the very common reasons for purchasing jewelry in the last couple of years.
Rhodium plating of gold and platinum jewelry
Both gold and platinum jewelry are rhodium plated (plated with rhodium). In the case of platinum, which itself has a very beautiful, noble metallic luster, rhodium plating helps protect it from gradually losing its luster during wear. For white gold, which, depending on the composition of the alloy, can have grayish or yellowish tints, rhodium plating is necessary to give it a uniform color and shine, exactly the same as we are used to seeing in jewelry advertising.
Allergic reactions to gold and platinum
Some people may have an allergic reaction to gold jewelry, especially if the alloy contains nickel. Platinum, on the contrary, is completely hypoallergenic and its content in the alloy is up to 95%, which means that the proportion of other metal in the alloy is practically negligible and cannot cause allergies.
What is the difference between gold and platinum in daily use?
When choosing a metal for future jewelry, especially if these are wedding rings , which will have to be worn almost without taking off, the physical properties of each of the metals come first. Platinum is stronger and more resistant to minor scratches in everyday life. Gold, especially high-grade gold, has a chance of being scratched much faster.
Minor damage and scratches on the jewelry can be eliminated after additional rhodium plating during regular maintenance of the jewelry, which, by the way, both gold and platinum jewelry periodically need.
Which metal should you choose, gold or platinum?
When choosing jewelry for yourself or the woman you love, especially when it comes to symbolic jewelry such as engagement or wedding rings, be sure to pay attention to the metal and compare the set of properties of each metal with your expectations from the jewelry.
At the Zbird Jewelery jewelry store, you will definitely be offered all available designs in both gold and platinum at your discretion, as well as free warranty service for all jewelry.

Features of platinum products
Platinum is primarily a precious metal, deposits of which are located near gold-bearing ores. The first acquaintance with platinum occurred during the time of the conquistadors. The conquerors of America dreamed of gold mines, but when they discovered them, they were disappointed. The gold they found was mixed with an unknown gray metal that resembled silver.
Platinum and white gold rings
No amount of manipulation could separate gold from this metal. It did not melt well, the product was dull and had a grayish tint. In this regard, the Spaniards did not pay attention to platinum, the value of which at that time was much lower than the value of silver.
Much later, in the second half of the 18th century, King Louis XVI of France drew attention to platinum as a metal for the manufacture of precious items. The treasury of that time was empty, gold items were melted down and sold, and platinum took their place.
Platinum is the strongest and most durable of precious metals. Metal color - white. Platinum is used to make earrings, rings, chains, pendants and bracelets. The metal is used in technical production. The cost of platinum products is high, which is due to its minimal quantity. There are not many mines on the planet where platinum is mined, and besides, it is still a refractory metal, which creates difficulties in the smelting of certain products.
The highest standard of platinum is 950, the lowest is 850. There is also a 900 standard of platinum. In most cases, in any platinum product the amount of metal is at least 95%, which also affects the cost. The price of 1 gram of platinum sometimes exceeds 4-5 thousand rubles.
In the West, platinum products are valued very highly. This metal has long turned into a profitable investment. When choosing whether platinum or gold will be chosen as the metal for decoration, you should be especially careful.
Products made of platinum are not affected by time, they do not deform, and there are no scratches on rings and bracelets. Unlike silver, platinum does not tarnish or lose its shine even after many years. The latter applies only to high-quality platinum products. To avoid tarnishing, manufacturers coat products with a layer of rhodium.
Rhodium is a noble but brittle metal, which is why it is used exclusively as a coating. Rhodium tends to wear off, but in the case of a platinum brooch, ring or earrings, this is not a problem, since the original color will remain the same.
White gold or platinum: how to distinguish and what to choose?
Due to their silvery hue and picturesque shine, platinum and white gold are popular materials for creating jewelry. Accessories made from these metals have a refined and noble appearance and are suitable for various outfits and accessories.
Compared to yellow or red gold, white gold is more expensive due to the high cost of the metals that are used to create this alloy.
Gold in its original form is soft, so in the jewelry industry it is used only in an alloy with several other metals, which give the product strength. These additives are called ligatures.
Why is it important to know how to distinguish platinum and gold?
Knowledge about precious metals and the distinctive properties of each of them will help you make the right, informed choice when buying jewelry for yourself or as a gift.
Differences between platinum and white gold
If we consider how platinum differs from white gold, there are quite a lot of differences:
- Platinum is an independent chemical element. The noble metal is designated Pt (Platinum). White gold is an alloy of pure gold (Aurum) with other metals such as palladium or nickel;
- Platinum jewelry is almost entirely (most often 95%) composed of this element due to its strength - the highest among jewelry metals. These products may be hallmarked as 850, 900 or 950. White gold is most often 700-carat, but also comes in 500-carat and 585-carat;
- platinum is a completely hypoallergenic metal. White gold items can cause skin irritation or rashes if nickel is present in the alloy. To give the jewelry anti-allergic properties, palladium is added to the alloy;
- Pure platinum has a silvery tint, and rhodium plating is used to give the accessory a more attractive appearance. White gold has a yellowish, almost sandy tint. The silvery color and shine is given to it by the coating of rhodium, which in most cases is used to cover jewelry made of this metal;
- the price of platinum is 3 times higher than the cost of white gold.
How to distinguish platinum from white gold
As for the appearance and color of the jewelry, it is almost impossible to distinguish these two precious metals; for this reason, you can hear opinions that platinum and white gold are one and the same.
Indeed, if the jewelry is coated with a layer of rhodium, which is used to give the products a silvery tint and an attractive shine, then there are no visual differences. However, on white gold jewelry, the rhodium plating may wear off, resulting in yellowish areas. The solution may be to re-plate the product with rhodium.

What is the difference between platinum and white gold?
Jewelry amazes with the richness of its choice. Platinum, gold of various shades, silver - each of the metals is beautiful and interesting in its own way. They all have different properties and are used in different fields. This article will help you understand the differences between platinum and white gold.
Historical information
In jewelry, platinum is the most expensive metal. However, it did not immediately become valuable. The name platinum was given by the Spanish conquistadors, who in the mid-sixteenth century became acquainted with this previously unknown metal. From Spanish plata means “little silver”, “small silver”. This name explains the refractoriness of the metal, due to which it was little valued. The initial cost of platinum was two times lower than the cost of silver.
Platinum found its use only at the end of the eighteenth century, when jewelers learned to process it. At this time, she gained popularity among royalty. King Louis XVI of France was the owner of a huge collection of platinum jewelry.
For a long time, platinum was considered a metal for men and was used to make link bracelets, large signets, and, a little later, cufflinks and chains. Women more often preferred white gold. Now these distinctions have disappeared.
Differences between white gold and platinum
These two metals differ in many ways:
- The most important difference between platinum and white gold is the composition. Platinum is an almost pure natural metal. White gold is an alloy of gold, silver, platinum, zinc, palladium and other metals. Pure gold in jewelry is mainly 585 or 750 grams per kilogram.
- Visually, platinum has a natural white-silver color. White gold is given its color by its accompanying metals. Compared to platinum, the color of white gold is grey, grey-yellow or brown. Thanks to this, colorless diamonds look more advantageous when set in platinum than in white gold.
- Gold itself is a very soft metal. That is why its alloys with harder metals are used in the jewelry industry. Platinum, on the contrary, is almost resistant to deformation and scratches.
- The metals that make up white gold are rare, but can cause allergies on the skin of their owners. Platinum is considered a completely hypoallergenic metal and products made from it can be worn by people even with very sensitive skin.
To give gold a light shine, it is coated with a thin layer of rhodium. This is a noble metal of natural silver-white color, similar in appearance to platinum, hard, but very brittle.
Rhodium plating does not tarnish and protects soft gold from unnecessary scratches, but, unfortunately, it can wear off over time. Therefore, products made from such gold are coated again over time.
Platinum does not require additional painting or protection from mechanical damage. Over time, it can fade a little, so it is also sometimes plated with rhodium.
Platinum jewelry is on average 11% heavier than gold, and the maximum gold standard, widely used by jewelers, is 750. The fineness of platinum jewelry is 850, 900, 950. In addition, platinum is much stronger than white gold. That is why it is a symbol of durability.
Prices for platinum jewelry are three times higher than the prices for white gold. This is due to the fact that the metal itself is considered more noble and its content in the finished product is higher. Platinum is less common in nature. In addition, working with it requires special skill from the jeweler. This is the most reliable material for setting all precious stones. White gold is inferior to it in its hardness.
Jewelry made of platinum and diamonds perfectly emphasizes the refined taste and status of its owner. Platinum is better than other metals at highlighting the beauty of diamonds.

Platinum is a rare noble metal of a beautiful silver-white hue, an element of the D.I. table. Mendeleev.
White gold is an alloy consisting of gold and other components (nickel, platinum, silver, palladium) that can color it white.
White gold and platinum: which is better for jewelry framing? Platinum compared to other metals
One of the most common dilemmas that buyers face when purchasing a ring or other jewelry is what it should be made of.
This question is especially relevant when choosing a material for framing a product that should securely hold stones.
Platinum and white gold are two of the most popular metals among people looking to buy white jewelry. Let's take a look at how these two materials compare and what their pros and cons are when used in jewelry.
Platinum versus white gold
Platinum is very rare, and therefore one of the most expensive metals used in jewelry.
This is one of the most expensive metals used in jewelry, and jewelry made from it is much more expensive than gold.
While the significant price can be considered a disadvantage, let's take a look at what platinum's advantages are and how it compares to other metals.
Durability
Platinum is one of the strongest materials that jewelry can be made from. This metal is also very resistant to corrosion and does not tarnish.
While yellow gold, for example, is softer and wears over time, platinum takes much longer to show signs of significant wear. Platinum may scratch, but it does not wear off or degrade over time as easily as gold.
Although platinum can bend, it is more difficult to break, and this quality makes it a very good choice for ring teeth.
For this reason, platinum rings require much less repair and their prongs are not easily broken or bent, making gemstones safer in a platinum setting.
Because of its hardness, platinum does not scratch as easily as softer metals and alloys (it does scratch, but is much harder).
This is why you don't need to polish platinum jewelry as often as yellow or white gold pieces.
White gold is also quite durable, but its hardness depends on its carat - the lower it is, the less pure gold the product contains and the harder it is.
Although higher karat pieces are softer due to the higher gold content, this is somewhat offset by the rhodium layer that is usually used to coat the gold alloy. The top layer of rhodium makes it heavier and more durable.
However, keep in mind that while a platinum prong may be easier to bend depending on the alloy content, gold prongs are more fragile and break more easily.
It's worth noting that white gold will lose its rhodium layer over time and will need to be re-plated. It is also more vulnerable to erosion caused by household chemicals such as chlorine.
Platinum, on the other hand, has no such problems.
Color
Even though these metals are both white, there is some difference in their appearance, especially as time passes.
Platinum jewelry gets scratched and develops a patina, causing the metal to lose its shine and take on a grayish, matte appearance.
If you want to restore the shine of your platinum jewelry, you will need to polish it.
However, if you don't mind that matte finish, you can leave it as is.
White gold does not develop a patina, but its rhodium layer wears away over time, revealing the underlying alloy of the piece, which has a yellowish color.
So if you want to keep it shiny and white, you will need to take care of it by periodically refinishing the rhodium plating.
Purity
One of the distinguishing features of platinum is that it is a very pure material. Platinum used in jewelry is typically 95% and 99%.
But why does cleanliness matter? Because of its purity, platinum can be worn without fear of allergic reactions.
While 10 or 14 karat yellow gold may cause skin irritation in people with allergies to nickel, which is often found in gold alloys.
Platinum, white gold and allergies
Platinum is hypoallergenic, meaning it will not cause rashes or skin irritation.
Some platinum alloys may contain nickel, which can cause allergies, but the levels in these alloys are so low that this is unlikely.
Gold alloys can sometimes contain nickel in concentrations high enough to cause a rash.
However, if the jewelry is rhodium plated, the coating will prevent the nickel from coming into contact with your skin.
Problems begin to arise when the rhodium wears off and the nickel-containing layer is exposed. In this case, you will need to re-plate the piece with rhodium as soon as possible.
You can also simply buy jewelry that does not contain nickel.
Comparison with other metals
Comparison with yellow gold
The most noticeable difference between platinum and yellow gold is the color, which makes each metal suitable for different gemstones and outfits.
However, the most important advantage of platinum is that it is not as soft as yellow gold, which scratches and bends more easily.
Platinum's durability makes it a good choice for jewelry intended for everyday wear.
Yellow gold, on the other hand, is more suitable for jewelry that you will wear less often, especially if it is higher karat gold and therefore softer.
If you are looking for a metal to set colorless diamonds in, platinum is the best choice.
Yellow gold makes any diamond set in it look a little yellowish, so while this metal is a good choice for slightly colored diamonds in lower-grade colors, it does not provide the best setting if you want to show off your colorless diamond.
Comparison with silver
Compared to platinum, silver is a softer and less durable metal. So if you're looking for a piece for everyday wear and want it to last longer, platinum is the clear winner.
Another problem with silver is that it tarnishes over time and you will need to clean your silver items more often.
However, the good thing about high quality silver is that it is much more affordable.
Comparison with tungsten
Although tungsten has a similar color, its main advantage is that it is much cheaper. Tungsten is just as difficult to scratch as platinum.
The disadvantage of tungsten is that it is very difficult to machine. For this reason, a tungsten ring is not as easy to resize as a platinum ring.
In addition, tungsten can only be engraved using a laser.
Comparison with titanium
Titanium and platinum are similar and both are safe for people with allergies, but titanium is a more affordable option.
Titanium is also much more durable than platinum and is very difficult to bend or scratch. However, scratches are more easily polished out on platinum.
Titanium is often preferred because it is much lighter. But you should keep in mind that just like tungsten rings, titanium rings are also difficult to resize.
Comparison with palladium
Palladium is very similar to platinum in terms of color and durability. Both metals are also hypoallergenic.
However, palladium is cheaper than platinum. Besides its lower price, the other main advantage of palladium is that it weighs less.
Weight: does it matter?
In general, platinum jewelry is heavier than comparable gold jewelry.
This might not make a huge difference, but weight can be a significant factor, especially if the ring has a relatively large diamond, for example.
So before purchasing, think about how platinum jewelry will feel compared to gold when worn over a long period of time.
Price
Although platinum has excellent strength, the high cost of this metal is one of its biggest disadvantages.
White gold has its pros and cons, but when it comes to making a purchasing decision, think about how much you're willing to pay for the benefits of platinum.
Choose a platinum ring if you will wear it often and want the jewelry to last longer. While platinum is scratched, these scratches do not result in loss of metal, but rather in displacement of the material.
If price is an important factor, then choose a white gold ring that you won't wear very often. This way you will pay less than for platinum jewelry, but be sure to factor in the cost of replating the piece with a new layer of rhodium every 3-5 years.
