I custom cut this focal bead out of genuine turquoise from the Kingman mine in Arizona. It has been stabilized but it has not been color treated. Weight is in the listing title as are the dimensions in millimeters. 2.5mm drill hole. CHAIN NOT INCLUDED. I only have a little of this material and when it's gone, it's gone! Check out the rest of my listings for more focal beads, pendants, cabochons, and specimens in many varieties other gemstones and upcycled material like Fordite.
