Our pendants are specially designed for maximum protection against corrosion (oxidation) and tarnishing. We accomplish this by using what's called a Galvanic Series to form a sacrificial anode. This is a metal that is more easily oxidized than the protected metal. Electrons are stripped from the anode and conducted to the protected metal, which, for this reason, is forced to become the cathode. As a result, the protected metal is made resistant to corrosion. Our pendants utilize this series in the Optimal Galvanic Order: 1) Nickel-plated pendants: brass base metal + copper plating + nickel plating. 2) Gold-plated pendants: brass base metal + copper plating + nickel plating + gold plating. 3) Rhodium plated pendants:brass base metal + copper plating + nickel plating + rhodium plating.
