Amethyst is a variety of quartz and owes its purple colouration to irradiation, the impurities of iron and transition metals and the presence of other trace elements, that result in complex lattice substitutions. It is the hardness of this mineral that makes it popular in jewellery making. This specimen was sourced from Brazil.
