Amethyst is February's birthstone
Amethysts are found in geodes, which look like ordinary rocks on the outside. Cracked open, a geode reveals sparkling raw amethyst crystals that range in color from light mauve to deep purple.
Amethysts supposedly had good powers. It was believed that they helped people stay awake and think clearly and protected against evil spells. At one time, you could only wear amethyst jewelry if you were royalty.
