Increases physical strength. Soothes and calms emotional stress. Opens the 3rd eye to the divine. Very visual and creative.

Amethyst is an extremely popular gem because of its attractive purple color. Like the word turquoise, the word amethyst is now the name of a color as well as the name of a gem material. While the word amethyst makes most people think of a dark purple gem, amethyst actually occurs in many purple colors.
