It's time to save! I was able to get these superb sets at a great price, and now I can pass the savings onto you. These necklaces average 18 to 21 inches in length. Earrings average 2 to 3 inches. These sets are made with colored agate and alpaca silver. Alpaca silver is an alloy of copper, iron, and zinc. There is NO SILVER content in these at all. If you don't love your purchase simply return it. Please review my policies page for more info. Feel free to ask questions and thanks for looking!
