Platinum, also known as platinum, is platinum in English, and its abbreviation PT is generally used as the code name. Platinum is a natural pure white metal, which is rarer than gold, with much less annual output, high density, strong acid and alkali corrosion resistance, oxidation resistance and more stable chemical properties than K platinum, so it is often used to make diamond rings.

K platinum is an alloy of gold and palladium/nickel/silver, zinc and other metals, so it is also called K platinum. The gold jewelry marked 18K platinum or 18KWG sold by merchants is a white alloy with 25% palladium or nickel added to gold, which is actually a kind of K gold with a gold content of 75%. The appearance of K platinum caters to consumers' love for white metal, so it is difficult to distinguish it in the eyes of laymen.

As gold, it is a bit rustic for young people to carry it.

But compared with K platinum, gold keeps its value, because the synthesis of K platinum makes its color incorrect. If it's not popular, it's hard to sell it again. However, as jewelry, it still has its advantages, such as being harder than gold, popular in white consumption, and lower in price than platinum.

However, gold does preserve its value. You can sell it when you need money badly, and the price of gold has been rising steadily in recent years, so it is better to buy it. However, if the economy is well-off, it is still recommended to buy platinum, but buy platinum marked with PT. Don't be fooled by the sales staff.
