29 ct natural precious BLACK OPAL from Lightning Ridge NSW Australia polished cabochon. High end Collector stone for display, this is not a piece for jewelry as it has very light fine crazing. If it were not crazed it would be worth $40k-$65k. Still, a very beautiful and great stone for display in a collection. Comes with the original GIA certificate Report #6137240567 dated April 2, 2011, which you can also verify online at the following link:
