Nice Large Rough Opal Specimen 131cts Lightning Ridge Green/Blues in Grey Base

I have for sale a Nice Large Rough Opal from Lightning Ridge Australia. This one weighs a hefty 131cts and is 40x32x17mm,.,. Its N6 Grey base with Green/Blue Fires through the middle. It has Good amounts showing at one end, then a smaller/thin amount at the other, but these bars do run all the way along through the piece. With some Slicing/Cleaning up and polishing this will make a few nice Cbas/Freeforms, Or keep as a huge specimen piece for a collector,.,.  Thanks for looking.,,.
