A 1.28ct boulder opal from Queensland sits at the centre of this 18K yellow gold ring, bezel-set and finished with a small bezel-set diamond alongside the stone. The opal carries a dark body tone that gives the colour real depth — bright green sweeps across the face first, blue trailing behind it, the two shifting as the ring catches the light. The setting is clean and close, so the stone reads front and centre on the finger. One piece.

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

Common Questions

Can the ring be resized?
Yes — this ring can be resized. Joseph or his jeweller can take the band up or down by a size or two; larger adjustments may be possible depending on the band's design. Resizing is best done before delivery so the ring arrives ready to wear. Get in touch with your size and we'll quote.
What does "dark body tone" mean for a boulder opal?
Body tone refers to the background colour of the stone — the backdrop behind the play-of-colour. Dark means the background sits in the deep grey-to-near-black range. In a boulder opal this dark effect comes partly from the ironstone host the opal is cut from, and it works the same way a dark sky intensifies fireworks: the green and blue colour play reads more vivid, more saturated, against that backdrop than it would on a lighter stone.
Is this a natural Australian opal?
Yes — a solid, untreated boulder opal from Queensland. Not a doublet, not a triplet, not synthetic. One stone, natural 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.

Each piece is one-of-a-kind. Once this stone sells, there is no other like it.
