Opal is a 'living stone' and thus should be protected
from extreme heat and harsh chemicals. (do not leave it on the

a greater hardness, some care needs to be taken when wiping opal
clean. Rinse first with cold water then wipe with a very soft,
Take care not to knock opal against hard objects
especially if set in a low hanging pendant as they tend to naturally

water for long periods or worn in the bath or shower because the
combination of heat and steam can compromise the integrity of
the glue used in their production. Solid opal has no problems
If you are having your opal set, make sure the person
is familiar with setting opal. Most reputable jewelers are familiar
with the properties of opal and should be able to set your opal
Most importantly of all wear your opal. It's far
too beautiful to be left in a drawer.
