Nice Koroit Opal Nut/Cab/Freeform 115.5cts Green Fires/veins Queensland Australia

I have for sale a nice quality Koroit Opal Cab/Freeform from Queensland Australia. This one is 115.5cts and 46x41x5mm. Claaic Koroit Nut with layers, different ironstone base colours, and then the Green, slight Blue veins in some band when moved. The middle has some nice Green Fires aswell. The back has slight fire in places. Great specimen piece for some, or would make a large pendant. Thanks for looking.
