This awesome set is made with Alpaca Silver and black cat's eye beads. The necklace is approx 18 inches long and the earrings are approx 2 inches. Alpaca Silver is an alloy of copper, zinc, and iron. It is lightweight and takes a lot of abuse. It is easy to clean and it will not tarnish. There is NO REAL SILVER in this set.
