Amethyst, a semi-precious variety of quartz, has had a long and interesting history over the course of civilization. The ancient Romans valued it as a stone which protected one against drunkenness. The name comes from the Greek word “amethystos”, which means “remedy against drunkenness.” At one time it was rare and worth more than gold. Amethyst has a spiritually uplifting effect, it is good for meditation, creativity, and for calming the nerves. It also helps ease addictions, and a piece of amethyst under a pillow can help promote a restful sleep.
