I. Foot gold jewelry content is more than 990 ‰, and the content of thousands of gold jewelry is more than 999 ‰. The gold content is not 100%, and the trace elements will cause discoloration.
. If gold is worn with white jewelry such as platinum or silver, due to the friction between the jewelry, the surface layer is discolored and scratched.
. When the foot gold and thousands of gold jewelry are in contact with acid, there may also be erythema. This is due to its internal impurities elements that produce oxidation layers on the surface of the foot gold jewelry.

Oxidation, just go to the gold shop to wash.
That's not pure, is it 18K gold?
