Boulder Opal 39x22mm Free Form

This freeform boulder opal cabochon measures 39 x 22mm. It features the characteristic ironstone host with natural, earthy patterning in brown and dark tones, finished with a smooth polish. A versatile size for a custom pendant or a bold ring, with an organic outline that lends itself to creative bezel settings. Boulder opal is opal supported by its ironstone matrix, with the host rock forming part of the face. This piece offers the distinctive look collectors and makers appreciate in matrix-backed opal.
Please note: Natural gemstones may vary slightly in colour, clarity and inclusions. Product images are representative, and individual stones may differ.
