The Rainpool Pinfire - A small boulder opal with tiny rainbow‑like streaks and soft pools of colour shimmering across its purple pinfire, giving the cabochon a gentle, dreamy glow on both sides.

This small polished boulder opal cabochon glows with gentle purple pinfire across its low‑dome surface, catching the light with subtle flashes that shift as the stone moves.

The natural ironstone matrix adds warmth and grounding, giving the piece that classic boulder opal character.

Double‑sided and freeform in shape, it’s ideal for jewellery makers who love working with smaller stones - perfect for a delicate pendant, charm, or artisan ring.

With brightness 2, the colour play is soft and understated, making it a lovely accent piece for minimalist designs.

Sourced directly from miners, this cabochon is a one‑of‑a‑kind Australian opal full of quiet beauty.
