Follow these tips to prevent copper earrings from turning green. Copper tends to tarnish this way whilst it builds a ‘patina’. This is a protective layer chemically developed to preserve the metal and protect it from any harsh elements. Regular polishing is the best way to prevent this chemical reaction. A microfiber cloth can be used to remove skin oils from the jewellery.
It is also important you avoid wetting the copper earrings. Do not wear them while swimming, showering, or performing household chores. If they do encounter water, it is best to wipe them dry as soon as possible.
