Mogok Township, Pyin-Oo-Lwin District, Mandalay Region, Myanmar. A small but gem quality andalusite crystal (EDS verified) from Mogok district. It shows a rather well formed complex termination for the mineral, with matted surfaces dotted by etch pits.

Andalusite is formed in low pressure/high temperature environments, and the typical environment will be in argillaceous sediments (i.e., formed by clays or other fine grained sediments) in a contact aureole around an intrusion, but it is also commonly formed as a result of regional metamorphosis.

Andalusite is an aluminium nesosilicate mineral with the chemical formula Al 2 SiO 5. This mineral was called andalousite by Delamétherie, [3] who thought it came from Andalusia, Spain.

Andalusite is a polymorph of kyanite and sillimanite. These three minerals share the same formula, but are stable at different P/T conditions.
