Here is a very pretty piece of calcite onyx. I have also seen this material sold as Mexican Blue Ice or Lapis Lace. This stone has a flat back and can be bezel set, prong set, or wire wrapped. It is polished on front and back with a final polish on 60,000 grit diamond.
Size: 23 x 15 x 5 mm Shape: Rectangle Clarity: Semi Translucent Origin: Mexico Treatment: None Known Hardness: 3.5 - 4.5 Weight; 17 cts.

I can no longer ship stones to China. The Chinese government prohibits the importation of gemstones, and I lost a large order because of this.
