39 Carats Natural Australian Opal Stone, White Coober Pedy In The Rough. Love the large opal stones this is a chunk. Shining bright all of the rainbow colours. It has some cracks but they may clean up. You can cut it up to multi stones. It is priced lower because of the cracks otherwise it would be a 1000 plus stone. There is a lot of bright colours all around the stone. 28x22x12mm
