Quartz compound consists of one part silicon and two parts oxygen i.e. Silicon dioxide (SiO2). The atoms are linked in a continuous SiO4 Silicon. Oxygen Tetrahedral framework. Quartz exists in two forms, the normal + -quartz, and the high-temperature quartz, both of which are chiral. Pure quartz, traditionally called rock crystal or clear quartz, is colorless and transparent or translucent and has often been used for hardstone carvings. Common colored varieties include Citrine, Rose Quartz, Amethyst, Smoky Quartz, Milky Quartz, and others. These color differentiation arise from chromophores which have been incorporated into the crystal structure of the mineral. The above prices are for FOR.
