Solid Boulder Opal with Pre-Drilled Hole

This Solid Boulder Opal with Pre-Drilled Hole is a generous 80.45 carat cabochon, shaped into a softly triangular drop that sits with satisfying presence. Across its dark ironstone body, warm chocolate and ochre veins web and curl like a topographic map, with scattered pinpoints and flashes of electric blue and teal surfacing as the stone moves. The high polish draws light cleanly across the dome, revealing layers of earthy patterning and subtle depth beneath the surface. Pre-drilled for easy stringing, it’s a ready centrepiece for a bold pendant or a collector’s display piece that celebrates boulder opal’s natural architecture.
