20142 - Beautiful Purple Natural Amethyst Crystals Cluster Minas Gerais District - Brazil Pterosaur claws This is a piece worthAmethyst is a purple variety of quartz (SiO2) 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 hardness of the mineral is the same as quartz, thus making it suitable for use in jewelry.
