To buy gold jewelry, we must first recognize the quality inspection marks of gold jewelry. Most of the gold ornaments sold in the market are equipped with inspection marks of quality inspection institutions, which clearly indicate the gold content and weight of the ornaments.
999 gold is also called thousands of gold, and the gold content is not less than 999 ‰; 990 gold is called pure gold, and the gold content is not less than 990 ‰; The gold content of 22K gold is not less than 916 ‰; 18K gold has a gold content of not less than 750 ‰; 14K gold has a gold content of not less than 585 ‰; The gold content of 9K gold is not less than 375‰.
Pure gold: Gold with a gold content equal to or greater than 99%, commonly known as "Erjiu Gold". The stamps are "pure gold", "99 gold" or "G99".
Thousands of pure gold: gold with a gold content equal to or greater than 99.9%, commonly known as "Sanjiu Gold" and marked with "Thousand Pure Gold" or "999 Gold" or "G999". Therefore, pure gold is definitely pure gold, but pure gold is not necessarily pure gold.
