Firestorm - A boulder opal that looks like swirling fire trapped in a silver heart, its colour flashes twisting like tiny flames in motion.
This charming boulder opal doublet ring features a bright oval opal wrapped in a polished 925 silver heart‑shaped frame.
The 8 × 7 mm stone shows vivid rolling flashes of red, blue and green, shifting beautifully as the ring moves.
With brightness 5, the colour play is exceptional - lively, saturated and full of personality.
The polished silver heart adds a sweet, romantic touch while keeping the design elegant and wearable.
A miner‑direct piece that blends premium opal colour with a meaningful, gift‑ready design.

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.
