A solid 4.02ct black opal from Lightning Ridge, set simply in sterling silver so nothing competes with the stone itself. Green flashes move across the dark body as the piece catches the light, giving it a lively, springy character rather than a heavy one. It's a substantial size for a pendant, with a straightforward silver setting that keeps it wearable day to day rather than reserved for special occasions. A genuine one-of-a-kind Australian opal, ready to wear as found.

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

Is this a natural Australian opal?
Yes — a solid, untreated Black Opal from Lightning Ridge, New South Wales. Not a doublet, not a triplet, not synthetic. One stone, natural colour.
What causes the green flash in this opal?
The flash comes from tiny silica spheres inside the stone that bend light and split it into colour — the same principle as a prism. On this stone that effect reads mostly green, appearing and shifting as the angle of light changes.
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.
