Solid Boulder Opal with Pre-Drilled Hole

A sculptural Solid Boulder Opal with Pre-Drilled Hole, cut as a generous oval cabochon and polished to a sleek, glassy dome. The body tone reads deep chocolate and plum-brown, with natural ironstone contours and soft, inky swirls that give the stone a moody, geological elegance. Across the face, fine seams and pockets of electric blue flare into view, with occasional hints of teal-green along the fracture-like lines—subtle, but vividly alive when the light catches. At 62.55 carats, it has a satisfying presence for a pendant or statement design, ready for stringing or setting straight from the drill hole.
