About Manganaxinite (Axinite-(Mn))

Manganaxinite is the manganese-dominant member of the axinite mineral group, a borosilicate mineral typically forming honey-brown to violet or yellow blade-like triclinic crystals with a vitreous luster. It occurs in contact metamorphic skarns, granites, and hydrothermal veins, with notable localities in France, Mexico, and Japan. The wedge-shaped crystal morphology characteristic of all axinites, combined with attractive transparent yellow or violet color in manganaxinite, makes it a collectible borosilicate gem.
