Copper Necklace and Earrings Set

Copper oxidation, or tarnishing, happens when copper reacts with moisture and air, forming a green patina of copper carbonate. Factors like humidity and chemical exposure can accelerate this process, changing the metal's look over time.

Copper can affect the skin; some people may experience allergic reactions, while others might get harmless green stains from oils and sweat. Proper care and maintenance can help minimize skin reactions and keep copper jewelry looking good.
