Caring for your Opals

Solid Opal is a soft stone so please treat gently to avoid damaging it

Most precious opals contain about 5-6% water, therefore, an opal may crack if subjected to very dry conditions or rapid changes in temperature. Try to avoid very high temperatures or low humidity extremes, such as boiling water or storing your gems in bank vaults or safes with very low humidity.

Cleaning your Opals

Solid opal can be cleaned gently with a mild detergent in lukewarm water and a soft cloth. Do not use strong chemicals and cleaners.

Never place your opals in an ultrasonic cleaner, as the intense vibrations may cause cracking in a solid opal, and water penetration in a doublet or triplet.

Small scratches and scuff marks can cause an opal to lose its shiny polish and become dull looking. If this is the case with your stones a professional polisher should be contacted to bring it back to life.

Storing your Opals

To store, simply place your opal in a soft cloth bag for protection and place it in a safe place where it won’t be knocked. If you need to store your stones in a very low humidity safe or vault, first wrap your opal in cotton wool with a few drops of water, then into a sealed plastic bag just to be safe. As the opal is impervious, the water will not soak into the but it will prevent water coming out of the stone.

Exceptions to the above

If your opal isn’t a Solid but is a Doublet or Triplet style the care is a little different.
