Amethyst

The most valued amethyst crystals are a milky, wine-dark purple. Some say the original Amethyst was a young priestess favored by both Sune and Selune. The two goddesses fought over the girl and, in their folly, destroyed her. A single glance from Selune turned the girl into moonlight, all silver and transparent. As the struggle continued, a goblet of wine fell from Selune's feasting table, splashing onto Amethyst and thus creating the gemstone's characteristic purple hue.
