Amethyst is a violet variety of quartz. The name comes from the Greek amethystos and methysko "intoxicate", a reference to the belief that the stone protected its owner from drunkenness. Ancient Greeks wore amethyst and carved drinking vessels from it in the belief that it would prevent intoxication.Amethyst occurs in primary hues from a light lavender or pale violet to a deep purple. High-quality amethyst can be found in Siberia, Sri Lanka, Brazil, Uruguay, and the Far East. "Rose de France" is defined by its markedly light shade of the purple, reminiscent of a lavender / lilac shade. These pale colors have recently become more popular.Geodes can form in any cavity, but the term is usually reserved for more or less rounded formations in igneous and sedimentary rocks. They can form in gas bubbles in igneous rocks, such as vesicles in basaltic lava or in rounded cavities in sedimentary formations. After the rock around the cavity hardens, dissolved silicates and/or carbonates are deposited on the inside surface. Over time, this slow feed of mineral constituents from groundwater or hydrothermal solutions allows crystals to form inside the hollow chamber.
When cut in half, visible bands corresponding to varied stages of precipitation may at times show patterns that reveal points of fluid entry into the cavity and/or varied colors corresponding to changes in chemistry.Geodes are found where the geology is suitable with many of the commercially available ones coming from Brazil, Uruguay, Namibia, and Mexico. Large, amethyst-lined geodes are a feature of the basalts of the Paraná and Etendeka traps found in Brazil, Uruguay and Namibia.
