Boulder Opals for Sale

Boulder opal forms in seams through Queensland ironstone, and is cut with its host rock as a naturally dark backing — so its colour can rival black opal while every stone keeps a free, organic shape that no two pieces share.

We source boulder opal first-hand through the trade networks our family has built since 1958, and grade it with the same body-tone and brightness system as our Lightning Ridge stones. See the opal types guide for how boulder compares.
