Opal : October Birthstone
Gemstone with multiple Elements; With its fascinating opulence of colors, resembling those of a magnificent rainbow following a summer rain, opal is the modern birthstone for October along with the alternate birthstone tourmaline, and the traditional birthstone for the Zodiac sign of Libra. The October birthstone derives its name from the Latin word "opalus," meaning' 'stone from several elements’. This means that the gemstone's striking play of light and its unique ability to refract and reflect wavelengths of light were known to ancient Romans in the days of Roman antiquity.
Opal in History and Legend; For centuries, writers compared opals to volcanoes, galaxies and fireworks, and gave extraordinary opals poetic names such as 'Pandora' and 'Light of the World'. The Roman Scholar Pliny the Elder (first century A.D) observed: "Some opals carry such a palette of colors within them that they equal the deepest and richest colors of painters. The this Kaleidoscopic gem encompassed "the red of ruby, the green of emerald, the yellow of topaz, the blue of sapphire and the purple of amethyst all glittering together". Ancient monarchs treasured Opals, both for their beauty and for their presumed protective powers. They were set into crowns and worn in necklaces to ward off evil and to protect the eyesight.
