Rock crystal is the colorless and most common variant of the mineral quartz (silicon dioxide, SiO2). The name 'rock crystal' is derived from the Greek word "Krustallos" which means ice. It was believed that rock crystal was ice shaped by the gods. The rock crystal was already known at the time of the Mesolithic. During the Roman period it was marketed from the Alps under the name "petrified ice". Theofratus called it "crystallos". Pliny the Elder also mentions it. The name "quartz" was introduced in 1529 by Georgius Agricola. The peoples of the East regarded rock crystal as a stone of patience and perfection. Tibetans use rock crystal to treat wounds. The choice of rock crystal as a drinking glass or as part of medieval jewelry can are attributed to the belief that these crystals would break or discolor when exposed to poison, thus making the chain an amulet that protected the king. Compare the Rudolphian Imperial Crown and the Chain of the Order of Jehovah. Origin: Megnatites, Pegmatites, Hydrothermal and alpine stone veins, alluvial deposits. Occurrence: Rock crystal is widely distributed in nature, but not always in gem quality. Historically known sites are India and Sri Lanka (Tatnaputi area). Iridescent quartz from the area of the Poona in India and from Myanmar is a rarity, beautiful crystals come from Kenya and Madagascar, also from Brazil (Minas Gerais), Goisas, Bahia and French Guiana. In the US rock crystal occurs in pegmatites, including in Maine (near Ausburn, New York, North Carolina, Arkansas (Crystal Peak) and California. Occurrences in the Alps are of particular significance. Rock crystals are found in Switzerland (for example near Urim where a crystal weighing 135 kg has been found in the area of Saint Gotthard and Grimsel), in Austria (a crystal weighing almost 1000 kg was found in a cavity near the Großglockner in 1965). Rock crystals also occur in Germany, the Czech Republic , Poland and France. There are unique cut rock crystals in the collections of various museums. The Smithsonian Institution Washington owns a 7000 carat cut stone and a spherical rock crystal with a diameter of 33 cm and a weight of 48.5 kg, which comes from Burma and has been sharpened in China.
