This outstanding Dark Base Coober Pedy opal weighs 10.65 carats and measures 17.8mm wide × 20.4mm long × 4.3mm thick. Cut into a beautiful Cabochon shape, this stone showcases a flawless surface and is polished to the highest standards.

The body tone is a rare dark base, originating from Coober Pedy — offering a black opal-like appearance, but with its own unique South Australian character. Dark base Coober Pedy opals are highly sought-after and not commonly found.

It displays a vivid Pinfire colour pattern, with small, intense flashes of red, green, blue, and violet throughout. The opal lights up brilliantly under both natural daylight and indoor lighting conditions.

This stone is flawless, with no inclusions, cracks, or faults. A perfect investment piece or a spectacular centrepiece for a high-end custom jewellery design.
