We can identify the authenticity of the platinum ring by looking at the logo.
If international regulations that all platinum jewelry must be marked with the word PT, such as PT990 jewelry or PT950 jewelry, PT900 jewelry, etc., because the platinum content is different Jewelry is really platinum jewelry, and those without these words are definitely not platinum jewelry. 1. Foot platinum: "Foot Platinum" or "PT990" mark. Refers to the gold jewelry with a platinum with no less than 990 among the thousands of points ratio. 2. 950 platinum: "Platinum 950" or "PT950" mark. Refers to the gold with less than 950 among the thousands of points. 3. 900 platinum: "Platinum 900" or "PT900" mark. Refers to the gold jewelry with a platinum with no less than 900 among the thousands of points ratio. 4. 850 Platinum: "Platinum 850" or "PT850" mark. Refers to the gold jewelry of not less than 850 among the thousands of points ratio. The expansion information: The precautions for buying platinum rings: The precious metal called 钯 钯 is easy to confuse with platinum. The golden mark of the golden gold is PD, which is different from the PT of platinum. It will also have numbers that indicate metal content, such as PD950.

In fact, it is simply platinum is an element, and platinum is a mixture. Platinum: Platinum (PT), which is more stable than gold, and the price is more expensive than gold. It is used to make high -end jewelry. The "PT900" or "PT950" seen on the products of jewelry stores represents the content of platinum in the jewelry of 90 % and 95 %, respectively. The general purity of pure platinum jewelry is 95 %, while the purity of 18K gold is only 75 %. It is impossible for any metal to be completely pure, with impurities and mixed with other metals. Platinum has almost no impurities, and the purity is extremely high, so it will not fade or change color, and it can still be shiny in the passage of time. Platinum pure white luster can reflect the real light of diamonds. Rare is 35 times rare than gold. Globally, only in very few places can be mining, mainly located in South Africa and Russia, as well as a few areas in Zimbabwe, Canada, and South America. Each year, only 88 tons of platinum is made into jewelry, while gold has 2700 tons. The number of platinum ore is less, the proportion of gold ore is 1 to 10. The density and weight of eternal platinum make it more durable than other jewelry. All valuable metals will leave scratches, and platinum is no exception. However, the scratches on platinum only move the metal and will not reduce its volume, and the gold scratches will bring wear and reduce the volume of gold. If there are indeed scratches on the naked eye on the platinum, qualified jewelry vendors can be polished for it. Platinum: a mixture containing gold (AU) and other small amounts of other metals. The maximum purity of Platinum in the market is 75%. It is mixed with 75 % gold plus 25 % silver, nickel, copper and other metals, which is white K gold. How to identify the difference between platinum and platinum r R R . The difference between platinum and platinum r r r r r r r r r r r r r r r r r r The differences between platinum and white K gold are mainly to see the mark on the jewelry. Essence Platinum jewelery of more than 990 ‰ of platinum is generally a "foot platinum" mark. The "P950" mark indicates a platinum with a color of 950 ‰. The white K gold is required to indicate the KK number. K means the gold content, such as 18K white, 750g, 750 gold, and AU750. The purity of platinum jewelry is not expressed as "K". The white K gold and K platinum jewelry sold on the market are not platinum jewelry. When buying platinum jewelry, you should ask the operator to issue an invoice. Write whether it is platinum or white 18K gold in the invoice. It is best to indicate the weight of the jewelry, so that it is easier to claim when the fraud occurs.
1. Observation color method: pure platinum is white, bright luster, white K gold color is white beige, and the color of silver is white. The surface color can be distinguished.
2, hand oscillating method: platinum density reaches 21.45, through the test of the same volume material, platinum has a heavy feeling, it is heavier than gold (19.36), heavier than K platinum, and heavier than silver (10.45).
3, burning method: Platinum melting point reaches 1773OC, much higher than K platinum and silver. Generally, the welding gun cannot melt the platinum, and it can be identified to the authenticity. And platinum is unchanged after cooling.
4, tags: platinum jewelry has standard poke. Internationally use PT or PD, such as PT950 platinum color is 950%.
5, gas natural method: Put the jewelry on the twisting gas stove, put it on a few minutes. If the jewelry becomes red and warmed up the gas stove, it is platinum products. This is because platinum can be used as a catalyst, which prompts the gas and air to oxidize the heat in the air, so that the platinum is warmed, red, and can ignite the gas.
6, point test method: A wipes mercury on platinum, platinum will not be contaminated, while gold and silver will be contaminated with mercury. B is placed in a hydraulic bottle in the edge or middle depression of platinum jewelry in the depression of the platinum jewelry. Platinum can be used as a catalyst to promote hypoxic decomposition, and the oxygen is released up and down.
