Hello! Many people are not sure about the difference between platinum and platinum. In fact, simply speaking, platinum is an element and platinum is a mixture. Platinum: Platinum is chemically more stable than gold and its price is higher than that of Huang Jingui. Used to make high-end jewelry. The "Pt900" or "Pt950" seen on jewelry products represent that the platinum content in jewelry is 90% and 95% respectively. The purity of pure platinum jewelry is generally 95%, while the purity of 18k gold is only 75%. No metal can be completely pure, and there are impurities mixed with other metals. Platinum has almost no impurities, and its purity is extremely high. It will not fade and change color, and it can still maintain its luster over time. The pure white luster of platinum can well reflect the true light of diamonds. Rare platinum is 35 times as rare as gold. In the world, it can only be mined in a few places, mainly South Africa and Russia, as well as a few areas in Zimbabwe, Canada and South America. Only 88 tons of platinum is made into ornaments every year, while 2700 tons of gold. The quantity of platinum ore is less, and the ratio of platinum ore to gold ore is 1 to 10. The density and weight of Eternal Platinum make it more durable than other jewelry metals. All precious metals leave scratches, including platinum. However, the scratches on platinum only move the metal and will not reduce its volume, while the scratches on gold will bring wear and reduce the volume of gold. If visible scratches appear on platinum, qualified jewelers can polish it again. Platinum: A mixture containing gold (Au) and a small amount of other metals. The highest purity of platinum visible in the market is 75%. It is made of 75% gold and 25% silver, nickel, copper and other metals, that is, white gold. Marked as 18K platinum, 750 platinum, 750G, etc. How to distinguish platinum from platinum depends mainly on the imprint on jewelry, in which the ring will be marked on the inner ring and the necklace will be marked on the buckle. Platinum jewelry containing more than 990‰ platinum is generally marked with "sufficient platinum". The symbol "P950" indicates platinum with a purity of 950‰. Platinum should be marked with KK number. K refers to the gold content. For example, those marked with 18K white, 750G, 750k gold and Au750 are all platinum with a gold content of 18K. The purity of platinum jewelry is not expressed by "K". White gold and platinum jewelry sold in the market are not platinum jewelry. When purchasing platinum jewelry, the operator should be required to issue an invoice, and the invoice should indicate whether it is platinum or white 18K gold. It is best to indicate the weight of the jewelry, so it is easier to claim compensation in case of fraud.
