This is the story of how Amethyst got its purple color.
Dionysus is the Greek god of wine. The legend goes that one day he became so angry at a mortal who had insulted him that he swore revenge, vowing to kill the next mortal who would come across his path.
Dionysus set a type of trap using tigers to do his dirty work. A beautiful young woman walked by the trap on her way to pay tribute to the goddess Artemis.
Artemis seeing the woman was in danger, quickly turned her into a statue of pure crystalline quartz. This protected her from the tigers, but unfortunately she was now a quartz statue!
When Dionysus saw what he had done to this beautiful woman, he was overcome with tears. He wept tears of wine. He wept and wept. His tears streamed all over the quartz statue. The quartz statue was now purple.
And that is the story of how Amethyst got its color (and name)!
