Amethyst was used as far back as the Egyptians in prayers for protection. It has been carved into the scarab worn around the neck. However it's true namesake "Not Drunk" comes from Greek mythology. The tale of the Roman God of wine, "Bacchus" is below:
The Tale of Bacchus
Long ago, a beautiful maiden was on her way to worship at the Temple of Diana. However, she had the misfortune of crossing paths with the god of wine, Bacchus. Angered since he’d just suffered some slight, he’d vowed to take revenge on the next person he met. He spied the maid and unleashed his two guardian tigers upon her. As the great beasts bounded towards the hapless lass, the goddess Diana intervened. To spare her such a terrible fate, she turned her into a pure, clear stone.
Immediately, remorse seized Bacchus. To atone for his actions, he poured his wine over the stone, staining the crystal a deep, violet hue. And so, the maiden Amethyst lent her name to the crystal.
