    Mohs Hardness - 5.5-6.5 Found in - Mexico, Australia, Brazil, Denmark, Ethiopia & Guatemala History - Opal is a semi-transparent solidified mineral composed of silicon and water. Fire Opal refers to the bright yellow to red color of the stone, with the most popular shade being a bright orange. The color is due to iron oxide and it usually occurs in volcanic areas, it also tends to be lighter in weight than other types of opal and contains somewhat more water. This stone can be cut as a cabochon, but is usually faceted if there is no play of color showing. The name is derived from the Latin opalus and Sanskrit upala meaning "precious stone". The Greek term opallios translates "to see a change in color". The oldest known opal mine is in Czechoslovakia and dates to 14th century. Popularity of opal suffered in 19th century partially due to Sir Walter Scott's novel of a cursed stone and was thought to be bad luck. Queen Victoria promoted the stone in 1800s by giving opal jewelry to her children. In the middle ages, the stone was thought to make the wearer invisible, and was highly recommended to thieves. It is a rather soft stone and needs care with handling. Do not immerse in hot water or use in a sonic cleaner.

In Mondern times it is said to stimulate sexuality, and stabilize the blood, it also increases the wearer's energy and enthusiasm.
