About gold jewelry

1, gold jewelry refers to jewelry made of gold as the main raw material. The chemical symbol of gold is Au, with a specific gravity of 17.4 and a Mohs hardness of 2.5. Gold ornaments can be divided into pure gold and k gold according to their gold content.

2. Pure gold jewelry is also called "99 gold", "all gold" and "red gold" because its gold content is above 99%, with a maximum of 99.99%. In order to overcome the shortcomings of gold, such as high price, low hardness, single color, easy wear and exquisite pattern, some other metal elements are usually added to pure gold to increase the hardness of jewelry gold, change its color tone and lower its melting point.
