Signs: Aquarius, Pisces, Scorpio, Sagitarius. Chakra: Crown chakra. Care: Once a month, the stone should be discharged under a flow of streaming water. Then mix with tumbled Hematite stones to recharge. This stone is not to be exposed to sunlight, because its colour will fade. Use: a tumbled stone, as a geode in the room, as a decoration or for jewelery. Its name Amethyst comes from the Greek, meaning "not under the influence". This is exactly what it does: clarity of mind. This effect was already known in ancient times, and in those times the stone was very valuable. Amethyst is an outstanding meditation stone.
