An Australian Black Opal is a stone of water and light. Because of its unique composition, it requires a different level of care than diamonds or hard sapphires. To ensure your Aura Opal retains its brilliance for generations, follow these simple guidelines.
1. Avoid Thermal Shock
Opals contain a small percentage of water (usually between 3% and 10%). Rapid changes in temperature—such as moving from a freezing winter day into a hot shower—can cause the stone to crack, a process known as "crazing." Always allow your jewelry to adjust to ambient temperatures naturally.
2. Cleaning with Precision
Never use ultrasonic cleaners or harsh chemicals on your opals. The best way to clean your stone is with a soft, damp cloth and mild, pH-neutral soap. Simply wipe the surface and dry it immediately. If your opal is set in a ring, a soft toothbrush can be used to gently remove debris from around the setting.
3. Smart Storage
Store your opal jewelry in a separate, soft-lined compartment. Because opals are relatively soft (5.5 to 6.5 on the Mohs scale), they can be scratched by harder stones like diamonds or even dust. If you live in an extremely dry environment, placing a small container of water in your jewelry safe can help maintain the humidity level.
