Quartz
Variety: Silicate
Hardness: 7 Density: 2.65 Composition: SiO2 The name of this mineral comes from the old German word, querertz (transverse vein). This is the most common mineral in the earth, constituting 12% of the mass of the lithosphere.
Its color varies depending on the presence of impurities, which is why we accept it in varieties such as rose quartz and amethyst for example. References |
