Nice Quality Koroit Opal Cab/Freeform 40.04cts Veins/Patterns/Double Sided Red/Green/Blues

I have for sale a Nice Quality Cut/Polished Koroit Opal Cab/Freeform from Queensland Australia. This one weighs 40.04cts and is 38x22x6mm. Ironstone base material with Classic Koroit pattern throughout. Green/Blues and some Reds in the front, then mostly Purple/Blue in the back/sides. Much more colour when moved than my pics would suggest. Thanks for looking.
