The Cocoonflare - A Yowah boulder opal with a shape like a tiny egg or cocoon, its warm orange outer ring encircling soft white opal forms that glow inside like a luminous life‑core wrapped in natural stone.
This teardrop Yowah boulder opal pendant shows a beautiful mix of white, green, and purple broad flash across its polished surface, shifting vividly as the stone moves.
With brightness 4, the colour play is lively and eye‑catching, standing out against the warm ironstone base.
The freeform teardrop shape gives it a natural, organic elegance, while the drilled finish makes it easy to wear on your own cord or chain.
A miner‑direct piece full of character, perfect for everyday wear or as a unique artisan gift.

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.
