Made with silver 925, 950, and brass. The turquoise is natural Chinese turquoise, cut and polished from the raw stone and set in place. It has a wild appearance and is large, finished with a high dome. The brass bezel is cut with a random pattern to match the turquoise, making it rougher than usual. This is an original, one-of-a-kind piece derived from the style of Indian jewelry. It is handmade, so there may be some imperfections, but I would be happy if you like it. The chain is a reference item and is not included.
