Tradition, History and Lore 

The word Opal is adapted from the Latin term Opalus which came from the Sanskrit word Upala – which means ‘precious stone’

Writing before his death in 79 A.D., the Roman Pliny wrote of the opal as “Having a refulgent fire of the carbuncle (ruby or garnet), the glorious purple of amethyst, the sea green of emerald, and all those colours glittering together mixed in an incredible way.”

Roman - Ops, the Goddess of Fertility,  wife of Saturn 

Greeks – opallios – to see a change in color

Opals were valued above all gems around 250 BC 

During the middle ages Opals were considered good luck stones because the colors in the stone represented all the virtues of other stones. 

Blonde women wore the stone believing the stone would protect their hair from losing its color

Wrapping it in a bay leaf gave the holder the gift of invisibility. 

Napoleon presented his Empress Josephine with a magnificent red opal containing brilliant red flashes called the Burning of Troy. 


Sir Walter Scott’s Anne of Geierstein (Fiction) published in 1829 gave Opals a bad reputation. In the novel there is an Opal with supernatural powers and when bathed in holy water it turned gray and the owner died. The book was popular, during this year the sale of Opal went down by half and so started the rumor that opals were bad luck. 

Opal has been used by Native American Indian and the Australian aboriginal shaman to invoke visions.  Native American Indians also used the stone for their vision quests. Australian aboriginals used the stone for ceremonial dreamtime.
