Blueoasis - A boulder opal that looks like a tiny blue oasis set in warm desert stone, its green‑purple pinfire sparkling like life gathering around a hidden pool.

This polished boulder opal cabochon features a striking blue centre that draws the eye immediately, surrounded by soft green and purple pinfire that sparkles across the surface.

The natural ironstone matrix frames the colour beautifully, giving the stone an earthy depth and grounding that’s characteristic of true Australian boulder opal.

With brightness 3, the colours lift gently in the light without overpowering the stone’s organic charm.

Its teardrop shape and double‑sided finish make it a versatile choice for jewellery makers - perfect for a pendant, wire‑wrapped design, or a collector’s display piece.

Sourced directly from the miners, this cabochon carries the authentic character of Queensland opal fields.
