Interesting Polished Koroit Opal Specimen 98.24cts Conglomerate Nuts/Fires QueenslandI have for sale a nice Polished Koroit Conglomerate Opal specimen from Queensland Australia. This one weighs 98. 24cts and is 42x25x8mm. The Pods Fires are all in the front, Greens Blues and some Reds. There is also some cracks and slight pitting in the front too. Hence Specimen piece. It is solid, as the cracks dont go through the back, but they are there, i included some reflection type picture to show them. Still a very nice stone for a collector,
