Mohs Hardness: 5.5-6.5 Found in Australia, Austria, Honduras, Brazil, Mexico, Zimbabwe, Ethiopia and the USA. History: Opal is a semi-transparent solidified mineral composed of silicon and water. White Opal refers to the light background color of the stone behind the play of color (Rainbow color). 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". Opal is the primary birthstone for October and the accepted gem for the 13th wedding anniversary. 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. The Romans believed opal to be the symbol of hope and called it cupid paederos or the child as beautiful as love, they also considered the wearer to be safe from disease. The Arabs thought the opal fell from the sky with flashed of lightning and the Greeks thought it gave the gift of foresight and prophesy to the owner. Today, Australia is major source for opal and supplies abt 85% of the world’s opal. It is a rather soft stone and needs care with handling. Do not immerse in hot water or a sonic cleaner. Opal is graded by size/cut/rarity/base color/fire color/fire intensity/fire pattern and fire consistency. Metaphysical: said to assist in recalling past incarnations, to develop psychic powers, bring out inner beauty, and draw money and luck.
