Viridine is a green, manganese-bearing variety of andalusite.
Andalusite is a common metamorphic aluminum mesosilicate mineral, used along with its polymorphs kyanite and sillimanite (fibrolite) to determine temperature-pressure paths in metamorphic host rocks. The first specimens of andalusite were named in 1798 by Jean-Claude Delamétherie, and believed to be from the southernmost state of Andalusia. However, the specimens were actually from the town of El Cardoso, in the Guadalajara region in central Spain: Delamétherie supposedly thought the town was in Andalusia.
Gem-quality specimens of andalusite can display pleochroism, a phenomenon where minerals show different colors from different viewing angles, especially with polarized light.
