21 Carats Natural Australian Opal Stone, Coober Pedy In The Rough, Bright Bars, Large Stone full of bright colours. 28x18x7mm all colour with lots of reds and very bright greens. This is a a great possibility with low risk. I faced the edge of it and you can see what is under. This isn't the best colour and it is already very bright there inside there are two red bars that merge to full rainbow on the other end. Great value stone. Not often you get this size for this price with colour bars all around the stone.
