A spectacular natural Australian boulder opal of exceptional size and character — 7.48 carats in an oval cabochon cut, displaying the extraordinary play-of-colour that makes Australian opals the most celebrated in the world. Boulder opals are formed within ironstone host rock found exclusively in Queensland, Australia, giving each stone a uniquely dramatic contrast between the vivid spectral colours and the dark natural matrix. At 7.48 carats, this is a significant and wearable gemstone — a genuine collector's piece and a breathtaking centrepiece for a bespoke ring, pendant, or statement brooch.
Entirely natural with no treatment of any kind — what you see is pure nature.
