Polished Specimen - Blue Opal

These blue opal specimens are highly polished.

Opal is silica which contains water. Because of its lack of clearly defined form, it is classified as a mineraloid. It forms under relatively low temperatures, usually in fissures of almost any type of rock. Precious opals display play-of-colour while common opal does not. Opals come in nearly any colour of the visual spectrum. As a healing stone, opals are used to clear emotions and help balance chakras. They are also said to reflect mood and intensify emotions. This stone of hope is also said to bring good luck.
