QUARTZ STONE

The name Quartz is of German origin first used in 1530 by the German Humanist Georgius Agricola. Quartz is a hard, transparent trigonal mineral composed of silicon and oxygen atoms. After Feldspar, it is the most abundant mineral on the surface of the earth. The ideal crystal shape is a six-sided prism terminating with six-sided pyramids at each end. The molecular formula of Quartz is SiO2, and the crystal structure is hexagonal. It indicates that Quartz is made of the elements silicon and oxygen. It exists as a component of metamorphic, igneous, and sedimentary rocks. Quartz develops positive and negative charges when subjected to any tension.

The countries that are the main manufacturers of Quartz in the world are; China, Japan, and Russia.
