A one-of-a-kind 3.58 carat Australian Black Opal pendant, hand-set in 18K yellow gold with three bezel-set diamond accents. The opal carries a dominant vivid green broadflash with blue undertones that shift and move as the stone catches light — the hallmark of top-grade Lightning Ridge black opal.
The setting flows in an asymmetric gold curve that wraps the free-form stone, giving the piece a contemporary feel with the weight and presence of a proper heirloom. Suspended from a fine 18K gold-plated chain, it sits beautifully at the collarbone — bold enough to make a statement, refined enough for everyday wear.
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 green fire is particularly prized by collectors and is considered among the most valuable gemstones in the world.

Caring for Your 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.
Is the chain solid 18K gold or plated?
