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.

Size & Fit

All ring sizes on our website are listed in US/Canadian sizes. Please refer to our size chart to find your recommended fit. For the most accurate result, we suggest visiting a local jeweller who can measure your finger professionally with calibrated tools.
