Black Opal Pendant – 18K Gold, 2.96ct, Semi-Dark, Green Mixed Flash

A 2.96ct solid Australian black opal with a semi-dark body tone and a mixed flash pattern — dominant green shifting through the stone as the light moves across it. Joseph set this one in a close-fitting bezel of 18K yellow gold that cups the stone cleanly and lets the colour do the talking. The polished surface is smooth and catches light readily, so the flash reads well in everything from indoor lamplight to daylight. On a 45cm gold-plated chain, it sits at collarbone height — noticeable without being heavy.

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.
