Andalusite
Andalusite is a silicate mineral with the chemical formula aluminum silicate, Al2SiO5. It crystallizes in the orthorhombic crystal system and is characterized by a Mohs hardness of 7.5, a density of 3.15 g/cm³, and a white streak. It exhibits a vitreous luster and typically occurs in a range of colors including yellow, green, brown, and red. Andalusite is classified as a nesosilicate and is known for its prismatic crystal habit. It is commonly found in metamorphic rocks and is valued for its diagnostic properties in mineral identification.

Etymology
The mineral is named after the region of Andalusia in Spain, where it was first discovered.
Geological genesis
Andalusite is a nesosilicate mineral that typically forms in metamorphic environments, particularly in low-pressure, high-temperature conditions. It is commonly associated with the transformation of aluminous sediments during regional metamorphism.
