The Cratergold Vein - A freeform boulder opal marked with golden‑looking seams along one side, its soft green pinfire glowing gently like light pooling inside a tiny crater viewed from above.

This polished boulder opal shows soft green pinfire across its freeform surface, with tiny natural seams that add texture and authenticity.

The warm ironstone matrix gives it depth and contrast, while the double‑sided polish makes it visually interesting from every angle.

With brightness 2, the colour play is gentle and understated - perfect for earthy, organic jewellery designs or as a tactile collector’s stone.

Its smooth finish and natural miner‑cut character make it a charming, one‑of‑a‑kind piece.
