Made with silver 925 and 950. The turquoise is from China's Cloud Mountain, cut and polished from the raw stone. Natural, large, and voluminous with a beautiful black spiderweb pattern, it rivals the American variety. This is a one-of-a-kind piece. 17g This is handmade, so there may be some imperfections, but I hope you like it. The chain is for reference only and is not included.
