A jewel born of fire and passion, this statement ring unites the rare brilliance of Lightning Ridge black opal with the timeless allure of diamond and ruby.

The opal, alive with flashes of red, orange, green, and blue, tells the story of Australia’s most storied gemfields. Set in 18ct yellow gold, its undulating form is offset by a cabochon ruby in deep red and a constellation of brilliant-cut diamonds. Together they create a symphony of light and colour — dramatic, romantic, and wholly one-of-a-kind.

Handcrafted with the traditional carved wax cast technique, this design carries with it the essence of slow-made luxury: considered, enduring, and rich with provenance.

Take Care

Everyday care (all jewellery)

  • Remove prior to sport, manual tasks, showing/swimming, and sleep.
  • Avoid Impacts and sudden temperature changes.
  • Store pieces separately in soft pouches/compartments.
  • Clean most jewellery with warn water & mild detergent-free soap & a soft brush, then rinse and pat dry with a lint-free cloth.

Metal care — Solid gold (9K/14K/18K)

  • Wipe with a soft cloth after wear; avoid harsh chemicals and abrasives.
  • For mixed stone settings, default to the gentlest method suitable for the most delicate stone present.

Professional checkups

  • Have prongs/claws and settings inspected every 6–12 months, or sooner if you notice movement/snags or after a hard knock.

Resizing

  • We do not recommend resizing rings from our Lightning Ridge Opal Collection. Opals are highly sensitive to heat, pressure and vibration; resizing can crack or craze the stone or compromise adhesives in layered constructions.

Opal (cleaning)

  • Hand clean only: no ultrasonic or steam. Use a slightly damp soft cloth or a quick lukewarm, mildly soapy rinse; do not soak for long.

Delicate stones (handle with extra care)

  • Opal, peridot (and some garnets): avoid ultrasonic/steam and hard knocks; stick to gentle hand cleaning.
