Solid Boulder Opal

This Solid Boulder Opal from Boulder is a substantial 121.0 carat cabochon with a bold, painterly landscape of ironstone and opal seam. Across the surface, electric pinflashes of teal, green and cobalt lift from the darker matrix, with occasional warm sparks that read as gold to orange at the edges of the colour bars. The pattern is richly detailed—webbed and banded in places, then opening into broader chocolate-brown fields that emphasise the opal’s brightness when it catches the light. High-domed and well polished, it offers a tactile, sculptural presence suited to a statement pendant or collector’s display.
