Bergkristal Dubbeleinder hanger van 3,2 cm/h2>Rock crystal
Rock crystal is the colourless, transparent variety of quartz and consists of pure silica. It crystallises in the trigonal crystal system and often forms well-developed six-sided prisms with a pointed tip. Due to its clarity and glassy luster, rock crystal is one of the best-known and most widely used quartz varieties.
The mineral occurs worldwide, with important deposits in Brazil, Madagascar, Switzerland and the United States, among others. Rock crystal occurs in hydrothermal veins, pegmatites and metamorphic rocks. Its chemical formula is SiOâ‚‚ and its hardness is 7 on the Mohs scale. Well-known varieties of quartz such as rose quartz, amethyst and smoky quartz differ from rock crystal by their colour-causing inclusions or radiative influences.
