The name Opal was derived from the Greek word ‘Opallios’ meaning ‘to see a change of colour’. The ancient Greeks believed that opals were formed from the tears of joy wept by Zeus when he defeated the titans, and that the opal bestowed prophetic powers. The ancient Romans considered it to be a symbol of hope and good fortune. Many cultures to this day consider opal to be a lucky gemstone. Australian native Aborigines tell us that opal is our creator’s footprint, that touched the Earth at the base of a rainbow to bring harmony. Opal is one of the few gemstones that has been found outside our solar system on mars.
