The Cerebralstone Drift - A large boulder opal with soft blue‑green pinfire resting over an intricate, brain‑like matrix pattern, its gentle lines and contours giving it a calm, thoughtful, almost cerebral presence.

This large drilled boulder opal necklace has a soft blue‑green pinfire shimmer across its polished freeform surface, giving it a calm, earthy glow.

The stone retains natural miner‑cut character, with gentle imperfections on the back that speak to its authenticity and origin.

With brightness 1, the colour play is subtle and understated - perfect for those who love opal’s organic beauty without bold flash.

Its generous size and smooth, tactile finish make it a grounding, everyday statement piece.

Finished on an adjustable leather cord, it’s ready to wear straight away.
