Almandine, with the CAS number 1302-62-1, is a member of the garnet group of silicate minerals, primarily composed of iron aluminum silicate. Its chemical formula is typically represented as Fe₃Al₂(SiO₄)₃, indicating that it contains iron (Fe), aluminum (Al), silicon (Si), and oxygen (O). Almandine is characterized by its deep red to reddish-brown color, which is attributed to the presence of iron ions. It has a vitreous luster and a hardness of about 7.5 on the Mohs scale, making it relatively durable. Almandine crystallizes in the cubic system, often forming dodecahedral crystals. It is commonly found in metamorphic rocks, particularly in schists and gneisses, and is often associated with other garnet varieties. Almandine is also used as a gemstone and in abrasives due to its hardness. Additionally, it has applications in geology and mineralogy for understanding metamorphic processes and conditions.
