Opal
Opal received its name from the ancient Sanskrit word upala, meaning "precious stone". The Roman scholar Pliny described opal as "having the fire of the carbuncle, the brilliant purple of the amethyst and the sea-green of the emerald all shining together in incredible union". The Romans believed opal was the symbol of hope and purity. They called it "cupid paederos" (child as beautiful as love) and thought the wearer safe from disease. Early Arabs believed opals fell from the heavens in flashes of lightening that gave them their fiery play-of-color. Ancient Greeks also believed the opal had the power of giving foresight and the light of prophecy to their owners. Today, opal alternates with tourmaline as October's birthstone. Opal is also designated for the 13th wedding anniversary.

Special care should be given all opals. Avoid heat, strong cleaning solutions, ultrasonic cleaning and rough treatment.

Opal's primary source is Australia. Other sources include Brazil, Mexico and the U.S.
