10 Amethyst mineral specimens perfect for your rock tumbler Amethyst is a variant of quartz that owes its purple hue to irradiation, impurities of iron and in some cases other transition metals, which result in complex crystal lattice substitutions. The Greek word “amethystos” may be translated as “not drunken”. Amethyst was considered to be a strong antidote against drunkenness, which is why wine goblets were often carved from it. This may help some of you on a Saturday night but we recommend just drinking responsibly. Aside from giving you super human drinking powers that would put a frat boy to shame, Amethyst is a natural tranquilizer. It relieves stress and strain, soothes irritability, balances mood swings, dispels anger, rage, fear and anxiety. All of which could be rearing their heads right now. Once tumbled, they gleam with a brilliant shade of purple that’s easy to get lost in.
