The Emberflare Sprite - A small round boulder opal bursting with fiery flashes of red, green, blue and gold, glowing like a spark lifted from living flame and caught inside polished stone.
This dainty boulder opal doublet pendant packs a colourful punch, with bright flashes of blue, red, green, yellow and orange across its polished 5 × 5 mm round stone.
The broad flash pattern gives it lively movement and a rainbow‑like shimmer despite its petite size.
Set in 925 silver with an 18k gold‑plated finish, it has a warm, elegant look that’s perfect for everyday wear or gifting.
With brightness 4, the colour play is vivid and eye‑catching - a premium miner‑direct piece in a delicate, easy‑to‑style design.

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.
