Earthswirl Rivers - A boulder opal that looks like gentle green streaks swirling through earthy layers, with soft orange‑blue pinfire flickering like tiny sparks inside stone.

This polished, low‑dome boulder opal cabochon shows delicate streaks of green across the surface, complemented by subtle pinfire flashes of orange and blue that appear as the stone moves in the light.

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

With its double‑sided finish and freeform shape, it’s a versatile stone for jewellery makers - ideal for a pendant, wire‑wrapped design, or a collector’s display piece.

Brightness 2 keeps the colours soft and understated, making this cabochon perfect for designs that lean into earthy, organic beauty.

Sourced directly from the miners, it’s a one‑of‑a‑kind Australian opal with natural charm.
