Nice Large Koroit Opal Cab 66.4cts Green/Blue/Red Fires Queensland Australia

I have for sale this lovely and quite large Koroit Opal Cab from Queensland Australia. It weighs 66.4cts and is 41x24x5mm. Mixed base ironstones, Light and Darker Browns mixed through with mostly Blue/Green veins, patterns, and sthen some Pink/Reds in places on the front, and in a patch on the back. Photos dont do it justice.  Will make a quality pendant or similar, or add to a collection. Thanks for looking.
