A large black Crystal Opal in the rough weighing 27 carats. Flashing colours of red, blue, and green on black. From Mintabie, Australia.

I have a large selection of opals I am selling in the next few weeks. Follow me for updates on new listings, or click ‘sellers other items’. I will combine postage. Make a financial investment today, as opals are classed as “precious stones” and cannot be unnaturally replicated in the lab such as diamonds. Australian opals are becoming harder to mine, making their potential of increase in value opportunistic.
