This set is made with Alpaca Silver and fused glass. Alpaca Silver is an alloy of copper, zinc, and lead. It has NO silver in it. The sets I offer for sale come to you from Lima, Peru. These necklaces and earrings are lightweight and durable. I've put mine through the wash and they've survived with little or no damage. They are also easy to clean - just use some water and lemon juice, or buff with a dry silver polishing cloth. Best of all, these are hypoallergenic. I have the most sensative ears on earth and I can wear these earrings! As with all my other listings, these may be returned if you're not thrilled. I do combine - please look at my other listings. Feel free to ask questions and thanks for looking!
