Black Opal Ring – 18K Gold, 7ct, Blue & Green, Diamond Accent

A substantial 7-carat black opal takes centre stage here, its blue and green colour shimmering and shifting with every turn of the hand. The stone sits in 18 karat yellow gold, framed by delicate white gold detailing set with diamonds — a combination that lets the opal's fire read as the obvious focal point while the diamonds add quiet sparkle around it. It's a ring built to be noticed: substantial enough to anchor the hand, considered enough in its setting to read as fine jewellery rather than costume. As with every stone in this collection, it's one-of-a-kind — once this piece sells, the exact stone and setting combination cannot be replicated.

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.
