Amethyst Gemstones

Beautiful and sober purple variant quartz. Amethyst gems are present in myths and symbols.

From the Greek word AMETHYSTOS (not intoxicated), it evokes the color of the wine to which water has been added to limit their negative effects.  Violet amethyst is the "sister gemstone" of yellow citrine. Ametrine is the combination of amethyst and citrine, with its typical color-zone.

Amethyst gemstones are the gems most commonly associated with the color purple. The purple color can be bluish or reddish with grade of saturation from grayish / brownish to vivid.
