Description
Authentic Amethyst from the mines of Brazil is a highly desirable variety of the Quartz family. It is predominantly purple, with layers of creamy whites. Amethyst is a purple variety of quartz (SiO2) and owes its violet color to irradiation, iron impurities (in some cases in conjunction with transition element impurities), and the presence of trace elements, which result in complex crystal lattice substitutions. The hardness of the mineral is the same as quartz, thus it is suitable for use in jewelry. Amethyst is produced in abundance from the state of Minas Gerais in Brazil where it occurs in large geodes within volcanic rocks. Many of the hollow agates of southwestern Brazil and Uruguay contain a crop of amethyst crystals in the interior. Much of this mined by hand with picks & shovels.This bag weighs 8 oz. and will contain an average of 3-8 Gemmy pieces (Depending upon the individual piece size).
