Amethyst is a crystal that promotes inner calm, mental clarity and intuition. Purple amethyst, precisely on a chromatic level, is connected to the sixth chakra. It therefore works on the entire sphere of the nervous system, not only on a psychological level, but also with regards to pathologies such as fatigue headaches and migraines.
