Black Opal Pendant – 18K Gold, 0.86ct, Semi-Dark, Green Flash

This Lightning Ridge black opal sits in a slim bezel of solid 18K yellow gold, with a single diamond accent beside it. At 15×7 mm the stone is notably elongated — longer than many pendants at this carat weight — and that proportion means the green flash of colour travels across its face in a wide, rolling sweep rather than concentrating in a single point. Body tone is semi-dark: dark enough to give the colour drama, light enough that the stone still reads warm rather than heavy against the skin. On the chain — 18K gold-plated at 45 cm — it sits at the collarbone, where movement catches the flash repeatedly throughout the day. Offered as a single one-of-a-kind piece.

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.
