Carved Boulder Opal

- natural, flatback cabochons 

These Carved Boulder Opal Cabochons are true gemstone sculptures — hand-carved from natural Australian boulder opal to follow each stone’s original opal veins and ironstone matrix. Unlike standard cabochons, these sculptural forms preserve fossil-like textures, earthy patterning, and flashes of color shaped entirely by the stone itself. Polished to a high gloss and finished as jewelry-ready art stones, no two are even remotely alike. Boulder opal is rarely carved in this style, making each piece an exceptionally unique, highly collectible focal stone for statement jewelry or refined gemstone collections.
