When it comes to caring for opals, two rules apply:
Natural Australian Solid Opal
Solid, natural Australian opals are of similar hardness and consistency as glass or crystal and can break. Dropping your Opal on concrete or tiles could result in a chip or crack, so care must be taken when handling.
Other than a pinch of mindfulness, natural opals do not require special care and contrary to popular belief, they do not have to be stored in water once cut. Water does not affect your natural solid Australian Opal. We recommend you gently clean your opal with a bit of mild detergent, water, and a soft cloth.
Storing & Maintaining Your Opals
Solid Australian opals are best stored separately in soft materials such as silk or velvet. Other than that, opals do not require any special storage conditions unless they are being exposed to very dry, hot conditions for an extended period of time.
If your stone develops any scratches over time, you might want to consider having it professionally polished by your trusted opal cutter. Professional polishing will bring the colours out and make your stone look breathtaking again.
