Platinum is a precious metal that is naturally white in itself. The annual amount of platinum mined is only one twentieth of that of gold, and an ounce of platinum takes 5 months to be extracted from 10 tons of platinum ore. Domestic platinum jewelry usually contains 90% pure platinum and is marked with the pt900 logo. The white luster of platinum is natural and will not fade after long-term wear. The hardness of platinum makes it the best friend of diamonds. White K gold is white gold with certain alloys. It contains only 75% gold at most. White karat gold cannot be marked with the pt mark, and can only be marked with gold and purity according to its purity. For example: 18k white gold can only be marked with 18k, g750, etc. In the international precious metals market, the price of platinum far exceeds that of gold, and it is the most expensive of all precious metals. In addition, some white jewelry may also be made of silver or plated with white metal, which may reveal its original appearance over time. Therefore, platinum's purity, rarity, durability and its natural white luster are unmatched by white k gold. Therefore, in fact, some jewelry marked with platinum on the market are not platinum jewelry, so when choosing, it is important to look at the mark in the jewelry.
