The Greensmoke Heart - A sweet heart‑shaped pendant with a centre opal that shimmers in blue and green, its soft broad‑flash movement curling through the stone like gentle green smoke drifting across a blue sky.
This charming heart‑shaped pendant features a polished blue base with a vibrant Yowah boulder opal doublet set at the centre. The opal flashes with green and blue broad‑flash colour, shifting beautifully as it catches the light.
With brightness 4, the stone has lively, eye‑catching fire that stands out against the soft blue heart.
Set in stamped 925 silver, it’s a sweet, meaningful piece - perfect for gifting or adding a touch of colour to everyday wear.

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.
