will the copper turn my skin green?
unfortunately, copper oxidizes naturally and will react to humidity and other elements such as oil on your skin. It is completely natural and not harmful at all! I use a microcrystalline wax to prevent this for as long as possible but it is inevitable in long term wear. I tested this and the chain began to leave marks after 3 days of wearing nonstop. I have not experienced any discoloration on pendants.
