An amazing huge fossil clam shell weighing a total of 53 carats. From Coober Pedy, Australia. Photographed from all sides, flashing Opal colours across all sides of the specimen.

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. Australian opals are becoming harder to mine, making their potential of increase in value opportunistic.
