A solid Australian black opal with a dominant green play-of-colour, set by Joseph in a close bezel of 18K yellow gold. The polished surface sits flush in the mount, protected on all sides by the gold rim — a practical choice for a stone you'll wear rather than store. Green is one of the most sought-after colours in Australian opal, and this stone delivers it cleanly. On a 45cm gold-plated chain, it wears as an everyday piece with genuine gemological credentials behind it.

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

Opals are softer than diamonds or sapphires, so a little care keeps yours brilliant for generations.

  • Avoid knocks and hard impacts — store separately, ideally in a soft pouch or lined box
  • Keep away from extreme heat or sudden temperature changes
  • Never use ultrasonic cleaners, steam cleaners, or harsh chemical cleaners
  • Clean gently with a soft, slightly damp cloth — no detergents, no alcohol
  • Remove before swimming, gardening, or anything rough

Treated well, your opal will outlive you.

Provenance

Every opal at Rocks On The Rocks is personally hand-selected by Joseph Bernecki — Polish-born, Australian-raised, and a 30+ year veteran of the Australian opal trade. Joseph sources direct from the fields at Lightning Ridge, Quilpie, Winton and Coober Pedy, and hand-picks each stone for its individual character before it's set in his Sydney workshop. You can meet him in person any weekend at The Rocks Market, stall under the bridge, Sydney.
