| Topaze |
Chemical composition: Topaz has the chemical formula Al₂SiO₄(F,OH)₂, and is composed mainly of aluminium, silicon, oxygen and fluorine (or sometimes hydroxide instead of fluorine). Impurities and treatments can influence its colour. Hardness: Topaz has a hardness of 8 on the Mohs scale, making it a very scratch-resistant mineral, but it remains fragile to impact. Density: The density of topaz varies between 3.4 and 3.6 g/cm³. |
