Boulder Opal

Boulder opal has a boulder-like appearance and most commonly found in Queensland, Australia. Boulder opal has a dark-body tone similar to black or dark opals with thin veins or spots of colour present on the face of the opal. For this reason, the host ironstone rock becomes part of the boulder opal stone when cut and polished. 

Our Boulder Opal Collection consists of polished Boulder Opal Cut Stones and Rough Boulder Opal Stones.
