Amethyst is one of relatively few gemstones with the specific purpose of improving intellectual and cerebral thought. It has legendary powers to stimulate and soothe the mind and emotions. It carries the energy of fire and passion, creativity and spirituality, yet bears the logic of temperance and sobriety.
Amethyst has long been said to promote sobriety – both in the literal sense of preventing drunkenness, and in the metaphorical sense of developing an ability to think more clearly and not be clouded with emotion of any specific sort. That emotion might be blind optimism or blind pessimism but either way, it is blind – and amethyst can help you open your eyes.
