Formula: SiO2; Colour: Violet - Purple; Amethyst is the purple variety of quartz and is a popular gemstone. The name "amethyst" comes from the Greek and means "not drunken." This was maybe due to a belief that Amethyst would ward off the effects of alcohol, but most likely the Greeks were referring to the almost wine-like color of some stones that they may have encountered. Its color is unparalleled, and even other, more expensive purple gemstones are often compared to its color and beauty. Amethyst is most prevalent as small stubby pyramidal crystals. Amethyst also forms the internal lining of geodes, some of which can be over 10 feet tall and weighing several tons. (The above information is provided solely for informational purpose.
