Amethyst: The colour purple

Amethyst is the birthstone for February and the gem for the 6th and 17th wedding anniversaries. Amethyst was as expensive as ruby and emerald until the 19th Century, when Brazil’s large deposits were discovered. It was believed to prevent intoxication—amethystos means “not drunk” in ancient Greek.

Saint Valentine – The patron of romantic love wore an amethyst ring carved with the image of Cupid.

Leonardo Da Vinci – The artist wrote that amethyst quickens intelligence and gets rid of evil thoughts.
