Gold jewelry refers to jewelry made of gold as the main raw material. The chemical symbol of gold is AU, with a gravity of 17.4 and Mo's hardness is 2.5. Gold jewelry can be divided into two categories: pure gold and K gold in terms of gold content. The gold content of pure gold jewelry is more than 99%, and it can reach up to 99.99%. In order to overcome the shortcomings of high gold price, low hardness, single color, easy wear, and unspoken pattern, some other metal elements are usually added to pure gold to increase the hardness of jewelry gold and change its tone and reduce its melting point. The gold -alloy jewelry with different color heights and obviously different gold content, the term "karat" is crowned. The K gold system is the international popular gold metering standard. The complete statement of K gold is "Krat Gold" and gives K gold with accurate gold content standards, thus forming a series of K gold jewelry.
The gold content is not less than 999, which is called thousands of gold, which is the highest value of jewelry named names. The mark is thousands of gold, 999 gold, GOLD999 or G999. The mark of gold jewelry includes manufacturers' code, materials and purity, such as: X Gold 990, XAU990, X -foot gold, etc. Among them, letters X are the manufacturer code. When making jewelry with different materials or different purifications, materials and purity should be represented separately. When the jewelry cannot be printed due to too thin or too small, it should be attached to the logo containing the mark content.

Thousands of gold are written with thousands of gold, and thousands of gold is no longer produced anymore
Will write thousands of gold 999 or 9999
There are writing on the nameplate
