Matters needing attention in the maintenance of gold jewelry
Gold is soft and easy to deform, so try to avoid colliding with sharp objects when wearing it. Don't pull necklaces and other jewelry to avoid deformation, and avoid wearing gold jewelry, especially wearing rings when doing heavy work.
The hardness of gold is relatively low. For example, when gold jewelry comes into contact with chemical elements such as mercury or chlorine in organic chemical appliances such as body sweat or skin care products, white alloy attachments can be formed on its surface, which will be mistaken for gold discoloration. When you don't wear a gold ring for a long time, you should wrap it in flannel first, and then put it in a jewelry box to avoid rubbing against other jewelry.
