Amethyst is a purple variety of quartz and owes its violet color to irradiation, impurities of iron and in some cases other transition metals, and the presence of other trace elements, which result in complex crystal lattice substitutions. The meaning of amethyst varies from time to time and culture, which is why amethyst has different meanings in Feng Shui and focuses on increasing wealth. In ancient China, it was also used as a powerful tool to remove negative energies and drive away the hazards of daily life. Tibetans consider amethyst sacred to the Buddha and make prayer beads from it.
