This set is made with Alpaca Silver and glass. Alpaca silver is an alloy of copper, lead, and zinc. There is NO silver content at all. These are lightweight, pretty and very inexpesive. They are hypoallergenic, and very easy to clean. The necklaces average 18 to 21 inches and the earrings average 1.5 to 2 inches. These may be returned if you're not 100% pleased. Please see my policies page for more info. I do combine and I welcome questions at any time. Thanks for looking!
