About Our Opals
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 a small Australian mining family, from ethical and regulated opal fields.All photos are taken with a macro lens, remember to check the opal dimensions before purchasing.
