This nature inspired necklace is made of 22k gold bezeled pentagon-shaped Nevada mine #5 turquoise. (Other metal options available including Argentium silver, 14k gold, and 22k gold.) Call for quote. All of my pieces are 100% recycled green and never purchased from a mine. My work is guaranteed, see the policies link for more information. Contact me via email with any questions you have regarding my designs. I am always happy to help!
