What is the difference between white gold and platinum? How much does platinum cost?

In fact, it is simply said that platinum is an element, and white gold is a mixture. Platinum: Platinum (PT), chemically more stable than **, and more expensive than **, is used to make high-end jewelry.

The words "PT900" or "PT950" on the products in the jewelry store indicate that the platinum content in the jewelry is 90 and 95 respectively. The general purity of pure platinum jewelry is 95, while the purity of 18k gold is only 75. No metal can be completely pure, there are impurities, doped with other metals.

Platinum has almost no impurities and is extremely pure, so it will not fade or change color, and will remain lustrous over time. The pure white luster of platinum reflects the true brilliance of the diamond. Rare.

Platinum is 35 times rarer than ** and can only be mined in very few places around the world, mainly in South Africa and Russia, as well as in Zimbabwe, Canada, and a few parts of South America. Every year, only 88 tonnes of platinum are made into ornaments, compared to 2,700 tonnes. The number of platinum ores is less, with a ratio of 1 to 10 mines.

The density and weight of eternal platinum make it more durable than other jewelry metals. All precious metals leave scratches, and platinum is no exception. However, a scratch on platinum only moves the metal and does not reduce its volume, while a scratch on the platinum brings wear and tear, reducing the volume of the platinum.

If there are indeed visible scratches on the platinum, a qualified jeweler can re-polish it.

White gold: A mixture containing gold (AU) and small amounts of other metals. The highest purity of white gold visible on the market is 75%.

It is made by mixing 75 ** plus 25 silver, nickel, copper and other metals, that is, white K gold. How to identify platinum and white gold in 18k white gold, 750 white gold, 750g and so on.

The difference between platinum and white karat gold is mainly by looking at the imprint on the jewelry, where the ring will be marked on the inner ring, while the necklace will be marked on the buckle. Platinum-colored jewelry containing more than 990 platinum is generally marked with a "full platinum" mark. The "P950" mark means platinum in 950 fineness.

White K gold should be marked with the KK number. K refers to the ** content, for example, marked with 18K white, 750g, 750 gold, AU750 words are all white K gold with ** content of 18K. The purity of platinum jewelry is not indicated by a "k".

None of the white gold and white gold jewellery sold in the market are platinum jewellery. When buying platinum jewelry, you should ask the operator to issue an invoice, write clearly on the invoice whether it is platinum or white 18k gold, and it is best to indicate the weight of the jewelry, so that it is easier to claim in case of fraud.

Compared to platinum, platinum is of course worth more, and it's not a little higher.

What is the difference between white gold and platinum?

1. Thousands of pure gold.

Refers to pure gold jewelry with a metal content of 99 9, engraved with 999 or 1,000 gold character seals.

2. Pure gold. Refers to pure gold jewelry with a gold content of 99%, engraved with 99% or pure gold.

k**。Refers to jewelry containing 75 ** ingredients, and the remaining 25 are other ***, engraved with 18k or 750 marks.

K white gold. Refers to the ** jewelry containing 75 ** ingredients and the color is white, and the remaining 25 are other white ** genera, engraved with 18K or 750 marks.

5、pt900

Refers to platinum jewelry containing 90 platinum, the remaining 10 for others, platinum and palladium content of 950, and the imprint is pt900.

PT950 refers to jewelry containing 95 platinum components, and the remaining 5 are others***, and the imprint is PT950.

The metal composition is completely different, and on the list of chemical elements, one is gold and the other is platinum

Platinum, also known as platinum, its English is platium, generally its abbreviation PT as the code. The gold jewelry sold by merchants marked with 18k platinum or 18kwg is a white alloy with 25% palladium or nickel added to it, which is actually a kind of K gold, and its **content is 75%.

Platinum and karat gold can be distinguished from the following points:

Platinum is a natural pure white metal, K white gold is an alloy with palladium, nickel, silver and zinc and other metals, so it is also known as K white.

Platinum is rare, and the annual output is much less than **, which is precious.

Platinum has a high density, and a piece of platinum jewelry is 20% heavier than a piece of karat platinum similar jewelry.

Platinum is resistant to strong acid, alkali corrosion, oxidation, and chemically stable than K platinum.

Platinum jewellery is marked with the "PT" mark and its fineness. For example, "pt900" refers to the platinum products of the jewelry, and the platinum content is 90%. And the notation of K platinum is like "18kwg"!

Platinum is worth more.

Platinum ** is more expensive than platinum, platinum and platinum metal are two different products, both in color, or in the metal material have great differences, the natural cost is also different, platinum is generally more expensive than platinum.

White gold is a mixture of 75 ** and 25 other gold, which is relatively cheap, while platinum is different from white gold, the purity of platinum is generally as high as 90, and ** is hardly much different, so platinum is called "one of the most expensive metals".

Platinum has a long-lasting luster and looks very shiny, after all, it is a noble metal product, and the cost is naturally not low. In addition, platinum is also relatively dense, tough and wear-resistant, and not easy to deform, while white gold is softer and prone to deformation.

Platinum rings** are determined by a variety of factors

1. The style of platinum rings.

The ** of platinum rings has a certain relationship with the style. The style designed by well-known designers will naturally be higher, and the more simple style will be relatively lower.

2. The grammage of platinum rings.

Due to the different styles, the grammage of platinum rings also varies to a certain extent. The more grammage metal is used, the higher it will naturally be.

3. Inlay material and size.

The ** of platinum rings also has a certain relationship with the material of the setting. If it is set with diamonds, then depending on the size and color of the diamond, the platinum ring will also have a difference.
