About Our Opals
We only work with Australian opals, direct from #MinerToMaker.
Every stone is natural, untreated, and individually cut.
No two opals are ever the same - each piece is one‑of‑a‑kind.
We source directly from small Australian miners and cutters.
Every opal comes from Queensland’s ethical, regulated opal fields.
All photos are taken with a macro lens, remember to check the opal dimensions before purchasing.
