Platinum is PT, K platinum is white gold alloy, and the main component is AU. These are two completely different chemical elements. Platinum Nian Bojin is not white. The gold used in jewelry is generally alloys. In addition to thousands of gold, thousands of foot silver, in fact, there are very small proportion of impurities, but which one is caused by metallurgical technology restrictions. Generally K platinum, 18K 14K 10K mostly. There are also rose gold, mostly 18K 14K 10K 9K. 18K, here is 18/24, that is, 75%of 24K, which means 75%of gold, and the remaining 25%is other alloy ingredients, generally silver, copper, etc. The other ingredients determine the color of the metal. It can be silver -white, can be rose golden, and can be golden. Different alloy ratio will have different color effects. For example, 18K black gold is actually dark iron gray, and it is not black at present. Thousands of silver/gold/platinum are soft, so the shapes are generally more complicated, and the inlaid jewelry is precious metal alloy. The precious metal jewelry will be pierced. Generally, PT, PT, PT, and a three -digit of the rear represent the purity, such as 800,750, representing 80%, 75%. Platinum, gold, rose gold, use AU, or do not use AU to use k, 18k = AU750 = 75%gold. PT and AU are metals that do not produce chemical reactions, which means that they will not change color, do not rust, and have good tough ductility, which is convenient for making various shapes. The main differences between platinum and K gold are density and price. Platinum's gram unit price is higher than gold. Different purity differences in K gold are not small. Platinum silver white is cold, and the silver white of K platinum is slightly warm. Gold color choices are more. Platinum jewelry is usually plated to make it whiter and brighter, and the coating of the long time will wear. If you inlay the style, PT950, don't choose PT900, it is too soft and easy to break. It is best to choose a 18K K gold style. As for which one is delivered, the style is the first. PT and AU are both precious metals, not so much value gap.
Platinum looks good -looking, 99%of the gold you choose carefully, although it is not so flashy, but it is valuable than platinum. If you do n’t want to bring it, you can sell it. Money and gold are more valuable:
