Sea‑isle - A boulder opal that looks like a tiny island surrounded by a wild, churning sea, its green‑orange pinfire flickering like sunlight hitting rough waves while the warm ironstone beneath forms the “shoreline.” The rounded triangular shape adds to that map‑like feel - a little landform caught in swirling colour and motion.

This polished triangular boulder opal cabochon shows a lively green‑orange pinfire pattern across its surface, with natural ironstone matrix and a bonus round pattern on the reverse.

A lightweight, double‑sided stone ideal for a pendant, ring, or wire‑wrapped design.

    All photos are taken with a macro lens, remember to check the opal dimensions before purchasing.
