The Galaxflare Drops - Teardrop boulder opal doublets that look like tiny galaxies, their broad flashes swirling across each polished surface like cosmic clouds drifting through deep space.
These teardrop boulder opal doublet stud earrings shimmer with a vivid mix of red, blue, green, and purple broad flash - a rare and eye‑catching combination that dances beautifully in the light.
The polished teardrop shape gives them an elegant, elongated look, while the red and purple tones add a premium touch collectors adore.
With brightness 4, the colour play is bold and lively, making these earrings a standout choice for anyone who loves opal’s natural fire.
Each stone is set in stamped 925 silver for a refined finish, and as miner‑direct pieces, no two pairs are ever the same. Lightweight, vibrant, and full of 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.
