The difference between gold and platinum Which is better, gold and platinum?

On the market, white K gold and platinum are both white metals from the naked eye, which is easy to confuse, so what is the difference? K gold (or open gold) is an alloy formed by fusion of gold and other metals. The characteristics of K gold jewelry are that it uses less gold, low cost, and can be formulated into various colors, and has improved hardness, and is not easy to deform and wear. K gold is divided into 24K gold, 22K gold, 18K gold, 9K gold, etc. according to the amount of gold. The most common '18K gold' on the market in my country has a gold content of 18×4.1666u003d75%, and the mark on the jewelry should be '18K' or 'Au750'/'G750'. Platinum (Platinum, Pt for short) is a naturally occurring white precious metal. The purity of platinum jewelry is very high. The purity of platinum jewelry is usually as high as 90%-95%. Common platinum jewelry has a purity of Pt900 and Pt950. According to national regulations, only jewelry with platinum content of 850‰ and above can be called platinum jewelry and must bear the Pt mark (as shown below). Platinum jewelry is extremely pure, so it will not cause skin allergies. The white luster of platinum is natural and pure, giving platinum jewelry a unique appearance. Even if worn every day, platinum always retains the pure white luster as before. Platinumu003dPlatinumu003dPt ≠ White K gold. According to the national precious metal jewelry standard, only platinum can be called platinum. So 18K platinum is a wrong concept. Strictly speaking, it should be called 18K gold or white 18K gold. 18K white gold is a mixture of 75% gold and 25% other metals. Platinum and white K gold are completely different metals. The main component of white K gold is gold, which is a mixture of 75% gold and 25% other metals. Therefore it is a mixture of gold and other metals, not platinum (white gold). The price of white K gold is lower than platinum and gold, and it is now widely used in jewelry making. Platinum is thirty times rarer than gold and can only be mined in very few places around the world. If you pour all the platinum in the world into an Olympic-standard swimming pool, it will not be deep enough to cover the back of your feet, and gold can fill at least three swimming pools. 3 grams is only equivalent to the weight of a smaller platinum ring, and it takes about 8 weeks and a lot of energy to extract these platinum.
