Globeflare - A pair of opals that glow like tiny worlds in motion, their bright colour flashes swirling across the surface like shifting colours on a luminous planet.
These round boulder opal doublet dangle earrings glow with vivid broad flashes of red, blue, green and purple across their polished 5 × 5 mm stones.
With brightness 5, the colour play is exceptional - fiery reds swirling through cooler blues and greens, giving each earring the look of a tiny globe with desert‑red accents.
The two opals are set in 925 silver with an 18k gold‑plated finish, adding warmth and luxury to the design.
Lightweight, eye‑catching and full of movement, this miner‑direct pair is perfect for statement wear or premium gifting.

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.
