A ring alive with colour and movement, this one-of-a-kind creation brings together some of nature’s most remarkable treasures. At its heart lies a 5.85ct Lightning Ridge black opal, glowing with a floral pattern of blue and green fire — a stone that shifts with every glance.

Surrounding the opal, dark blue sapphires, sparkling white diamonds, and touches of warm orange-yellow and light pink add contrast and brilliance. The sculptural band in 18ct yellow gold is carved with flowing motifs, lending the piece both artistry and presence.

Handcrafted using the traditional carved wax cast technique, this ring is designed as a bold statement of individuality — an heirloom to be worn and remembered.

*For our Australian clients, pieces valued above €10,000 are available by private arrangement only. Please contact us to organise VIP delivery or studio collection.

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.
