120 Cts Natural Australian Opal Stone, In The Rough, Reds, Greens and Blues. It is a huge opal stone almost an ounce. It has plenty of colour through it specially in the thick part of the opal. There is also a thin part which may have nothing in it. It wont effect the price as most of it has thickness and colour. I wonder how this would face? It will make a good specimen because of its size. You may have fun with the Dremel and clean it up. The photos dont show the colour too well but it is there in abundance. size 53x31x13mm
