This boulder opal is cut as a cushion-shaped cabochon and bezel-set in a sterling silver band. The stone shows blue colour play with green undertones, shifting brightness as it catches the light from different angles — a natural effect of the opal's silica structure rather than anything applied to the surface. The silver band is plain and polished, keeping the focus on the stone.

About Boulder Opal

Boulder opal forms as veins of precious opal within ironstone matrix in the opal fields of Queensland — primarily Quilpie, Yowah and Winton. Unlike black opal from Lightning Ridge, the opal cannot be separated from its host rock; it's cut as a single solid piece, with the natural brown ironstone remaining as the stone's backing. This gives boulder opal its distinctive look — vivid colour against rich earth tones — and also makes it physically more durable than other opals, since the ironstone host is harder than the opal layer it carries.

Caring for Your Opal

Opal is softer than diamond or sapphire, so a little care goes a long way. See Opal Care for storage, cleaning, and what to avoid.

Common Questions

Is this a natural Australian boulder opal?
Yes — a solid, untreated boulder opal from Queensland. Not a doublet, not a triplet, not synthetic. One stone, natural colour.
Why does the colour look different in each photo?
Opal's colour play changes with the angle of light hitting the stone, so the same ring can look brighter and more electric in one shot and softer and more teal in another. That shift is part of what makes opal distinctive — it isn't a flat, printed colour.
Certification, shipping, returns?
Every piece is backed by Joseph's personal guarantee, ships fully insured within Australia, and can be returned within 14 days. See Buying an Opal for the full breakdown.
