Quality Black Opal N2 Opal Cab 8.42cts Lightning Ridge Blue/Green Fires Australia

I have for sale a Very Nice Cut/Polished N2 Black Opal Cab from Lightning Ridge Australia. This one weighs 8.42cts and is 18x12x4mm.  It has just over 1/2 the stone with Green/blue Fires when moved. Interesting stone with multiple patterns. It will make a Great pendant or similar as it is, or it could be recut to give a Solid Cab with Fires across the full face.  I dont have many Black Opals so grab a bargain,.., Thanks for looking,.,.,.
