Unusual Gem Koroit Opal Cab 45.28cts Pools/Ponds of Opal Bright Green Veins Qld Australia

I have for sale a Very Nice Gem Cut/Polished Koroit Opal cab from Queensland Australia. This one weighs 45.28cts and is 29x23x5mm.  Beautiful veins and pools of opal over the Reddish ironstone base. Blue/Green and some Red/Gold Fires when moved in this one. It will make a very nice pendant statement piece, or add to a collection. I have been selling opal for 23 years and never seen one quite like it. Thanks for looking.
