Shown here is a modified triangle turquoise. sky blue with brown matrix. The dimensions of this stone are 22mm. by19mm. by 6mm. deep. This stone is natural and not treated and probably from an American mine. Its old material Ive had for years and looks like it could be a Bizbee source and I can't be sure.
This is a nice hight dome gem and could be set up in a wire wrap since the back is polished. Nice pendant stone , but would also make a fantastic ring. Very pretty blue.
