Sterling Silver is an alloy of silver containing 92.5% by weight of silver and 7.5% by weight of other metals, usually copper.
Sterling Silver is perfect for everyday wear; you can go to the gym, shower, and sleep in it. It’s also hypoallergenic, so it’s great for people who
have sensitive skin. Sterling silver can tarnish if it's left out to
oxidize with air, so we recommend storing it in a sealed zip bag if you
are not wearing it. Getting it wet and wearing it often actually helps
prevent it from tarnishing.
