Precious metal jewelry (including platinum, gold, etc. ) occupies a very important position in the jewelry family with its charming color and preservation function. And all kinds of imitation jewelry (including forged gold, coated gold, etc. ) is favored by people because of its precious metal color and low consumption.
Imitation jewelry is sometimes passed off as precious metal jewelry by unscrupulous businessmen, but the value of the two is far from each other. If you look closely, you will find that all kinds of jewelry are engraved with different marks on the inner ring or the reverse side, which not only explains the types of jewelry, but also tells everyone the color of jewelry.
Pure gold: refers to the gold content of not less than 990, marked with "Gold", "Gold 990" or "G990".
Thousands of pure gold: refers to the gold content of not less than 999, marked with "Thousands of pure gold", "Gold 999" or "G999".
K gold: generally speaking, it refers to precious metal jewelry with a gold content of 8K-24K (1k = 4. 1666...%). The labels are 24K, 18K, 9K or 750 (i.e. 75% gold content, also called 18K) and.
In order to meet the needs of consumers, merchants have also developed and produced "lottery gold" in various colors. Color gold is added with various other metals such as aluminum, silver, cadmium, palladium, etc. Gold is used to make jewelry appear purple, pink, blue, green and gray. Lottery money is k gold. As we usually see, 18K platinum is often considered as a kind of platinum. In fact, 18K platinum is platinum, containing 75% gold, 10% silver, 10% zinc and 5% nickel. Hong Kong and Macao are also called "Dacheng K Platinum" or "330000000000000".
Foot platinum: the platinum content is not less than 990, and it is marked with "Foot Platinum" or "PT990".
950 Platinum: The platinum content is not less than 950, and it is marked with "Platinum 950" or "PT950".
900 Platinum: The platinum content is not less than 900, and it is marked with "Platinum 900" or "PT900".
850 Platinum: The platinum content is not less than 850, and it is marked with Platinum 850 or "PT850".
Other substances in platinum jewelry are mainly its kindred element palladium (Pb). For example, PT900 contains 90% platinum, 10% palladium, and so on. The platinum content in platinum ornaments is generally not less than 85%.
The fineness of silver ornaments is also expressed by one thousandth of the silver content.
Foot silver: the silver content is not less than 990, so it is marked with "foot silver" or according to the actual content.
925 Silver: The silver content is not less than 925, so mark "Silver 925" or "S925".
Gold plating: Using the principle of electrolysis, a thin layer of gold is plated on the surface of jewelry made of silver or copper. The thickness of gold-plated layer in China's industry standard is not less than 0.5um, even if it is thin gold-plated, it must be greater than 0.05um, and the gold-plated jewelry is marked as "GP" or "KP".
Gold plating: gold foil is plated on the surface of metallic materials such as silver and copper, and the fineness of gold foil is required to be not less than 10K, and the weight is not less than 1/20 of the total weight of the material, usually expressed by KF.
Forging gold: in essence, it is a kind of gold foil forging on the surface of other metal jewelry blanks at high temperature and high pressure. The fineness of gold foil shall be greater than 10K, in which the total amount of forged gold shall not be less than 5% of the finished product, and marked with "GF" or "KGF". Forged gold has strong surface hardness and high wear resistance, and it is not easy to lose the gold texture.

There is no other answer. Platinum has high temperature resistance, corrosion resistance and good chemical stability. If it's not pure white gold, it may be.
