The Cloudflare - A crystal opal that looks like a soft orange cloud glowing from within, its green flash drifting through the colour like light moving across a warm sky.
This solid crystal opal ring features a vibrant round stone that glows with green and orange broad flash, shifting beautifully as it catches the light.
The polished crystal opal has a soft clarity that lets the colours breathe, giving the piece a luminous, almost ethereal feel.
Brightness 3 brings a lively play of colour without overpowering the delicate size, making it perfect for everyday wear or stacking.
The rope‑style stamped 925 silver setting adds a touch of texture and elegance, while the adjustable band ensures a comfortable fit for a range of sizes.
A unique miner‑direct piece with a charming wing‑like silhouette, full of natural Australian opal character.

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.
