A matched pair of Lightning Ridge black opals, each 13×9mm and together weighing 3.20 carats, set in 18K yellow gold with bezel settings. The stones carry a dark body tone that gives the colour real depth — and from that dark ground, a green flash of colour catches the light as you move. A row of small diamond accents frames each setting, adding brightness at the edge without competing with the opal itself. The closures are French wires fitted with safety hooks, so they sit securely through the day. Two stones, one matched pair — the kind of piece you notice from across a room.

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

How are these worn?
These earrings have French wires with safety hooks — they pass through pierced ears and the safety catch holds them in place from behind, so there's no risk of losing one through the day.
What does a dark body tone mean for an opal?
Dark body tone means the background of the stone is deep — close to black but not all the way there. It's one of the features that makes Lightning Ridge opal so valued: the dark ground acts like a stage that makes the colour play pop rather than wash out. The green flash on these stones reads vivid because the backdrop behind it is so deep.
What is a flash of colour pattern?
A flash pattern means the colour doesn't sit evenly across the surface — it appears as distinct, concentrated bursts of fire that move as the stone catches the light. Turn the earring slightly and the green can seem to switch on and off. It's one of the more dramatic ways a black opal can present.
