Chemically, silver does not react with oxygen or water at ordinary temperatures and it does not tarnish easily. However, the other metal in the alloy (usually copper) may react with oxygen in the air. As the silver's purity decreases, it is more likely to corrode or tarnish. Although sterling silver does tarnish, our rhodium-plated jewelry provides maximum durability. Our jewelry is also easy to clean and care for. Try Berricle Silver Polishing Cloth.
