This ring carries a semi-dark black opal from Lightning Ridge — the kind of stone where the body is dark enough to give the colour real contrast, but warm enough that it never reads heavy on the hand. The dominant colour is green, vivid and strong, with blue moving through it as the stone shifts in light. The setting is a bezel in 18K yellow gold, finished with white gold detailing and small diamond accents that frame the opal without competing with it — the two-tone metalwork draws the eye toward the stone rather than away from it. Cut to AU size L, ready to wear or resize to suit.

About Black Opal

Black opal is the rarest and most sought-after variety of Australian opal, mined almost exclusively from Lightning Ridge in New South Wales. Its dark body tone — from dark grey to jet black — creates a dramatic backdrop that intensifies the stone's natural play-of-colour, producing vivid flashes that appear to glow from within. Black opal with strong fire is particularly prized by collectors and is considered among the most valuable gemstones in the world.

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

What does semi-dark body tone mean?
Semi-dark means the background of the stone sits between a light-bodied opal and a fully black one — dark enough to give the colour real contrast, light enough that the stone reads warm rather than heavy. In practical terms: the green and blue colour play has a strong, vivid backdrop, and the stone catches the light without looking opaque or flat.
What is the two-tone metal in this ring?
The ring is set in 18K yellow gold with white gold detailing — two alloys of gold used in the same piece. The warm yellow of the band complements the opal's green and blue tones, while the cooler white gold detail and diamond accents add definition to the setting without introducing a different metal into the piece.
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.
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.
