This necklace was both a challenge and pleasure to design and create. The stone, calsillica is made from leftover glaze used to make pottery. This particular one is from New Mexico. I set it in sterling silver and hung it on a handcrafted chain. I enclosed some pictures of the process. The pendant is 4 x 1.5 inches and the chain is adjustable up to 21 inches. Complimentary polishing cloth included. Free shipping within Canada and the US.
