Opal is the birthstone for October and is said to represent purity, loyalty, hope and wisdom.  The rumour that opals are unlucky was started by the diamond-mining industry many years ago, because opal was the only stone beautiful enough to rival the demand for diamonds. In fact throughout history many cultures believe that opals bring luck to the wearer.

Wearing opal jewellery is said to promote imagination, healing and dreams in the wearer. Tourmaline is an alternative birthstone for October.
