    • About Opal

      Hardness and toughness
      Opal hardness is variable depending on its exact composition and formation conditions, and ranges from 5 to 6.5 on the Mohs scale. Its toughness is very poor to fair, making opal a gem that is suitable for jewelry but requires care when wearing so as to not scratch or break the stone.

      Stability
      Opal is generally stable, but heat from intense light can cause fracture lines called “crazing.” High heat or sudden temperature changes can also cause opal to fracture.  Opal is attacked by hydrofluoric acid and caustic alkaline solutions.

      Cleaning
      The only safe way to clean opal is with warm, soapy water.
