Boulder Opal

Boulder opal keeps its ironstone. The colour forms in seams and pockets through the host rock, and the cutter leaves the two together — so the piece carries the country it came from as well as the fire.

Queensland boulder opal is found nowhere else on earth. Each stone is freeform, shaped by the seam rather than by a template, which is why no two of these pieces share an outline.

Read what boulder opal is, and why the ironstone stays on — including how to tell a solid boulder opal from a doublet.
