Its name derives from the Greek "amethystos" which means not drunk, hence the curious myths related to this gem.
Amethyst is the purple variety of the mineral species of quartz, its purple color can be cold and bluish or a reddish purple sometimes referred to as "raspberry". The amethyst crystals are found essentially inside geodes (internal cavity of an igneous rock , basically spherical in shape, covered with crystals).
This gem was as expensive as ruby and emerald until the 19th century, when the great deposits of Brazil were discovered.
Worldwide, the main deposits of this mineral are found in Brazil , Uruguay , Bolivia , India , Russia , Mexico , USA and Madagascar . In Bolivia, amethyst and citrine are found in the same crystal. The unique gems, called ametrines, are half purple and half yellow.
Its color ranges from pastel pink to dark purple and is produced from iron elements. Widely used in jewelry, it is more widely used in oval or octagonal cuts.
A mythological legend explains that Amethyst was a nymph of the woods of which Bacchus, the god of wine, had fallen in love; but the girl, to escape the unwelcome courtship, turned to Diana, goddess of the hunt, who transformed her into a limpid crystal. Angered, Bacchus overturned his cup full of wine on it, thus giving it its violet color, together with the power to protect the wearer from the intoxicating effects of the drink dear to him.
Amethyst is the birthstone for February and the gemstone for the 6th and 17th wedding anniversary.
