I have for sale a Nice Quality and large 115.3cts Koroit Opal Cab/Freeform from Queensland Australia. This one is 58x34x9mm.  Fully polished on all sides, pattern mixed with some ironstone, and the Gem Green crystal veins in the middle. Some fires around that and in part of the back. Interesting piece, would make a lovely pendant or add to a collection. That Green in the middle in Electric. Thanks for looking.
