Quartz is an abundant mineral in the Earth's continental crust. The Quartz Granules, which we offer, is made up of a continuous framework of SiO4 silicon oxygen tetrahedra, with oxygen being shared between two tetrahedra, giving an overall formula SiO2. There are different varieties of quartz, several of which are semi-precious gemstones. Throughout the world, varieties of quartz have been, since antiquity, the most commonly used minerals in the making of jewelry and hard stone carvings. We are reliable Quartz Granules Manufacturers, Suppliers and Exporters from Alwar (Rajasthan). Our Quartz Granules are procured from the finest mines in Rajasthan.
