Inesite is a hydrous calcium manganese silicate mineral.

Inesite is an inosilicate with a triclinic crystal system.

It has a Mohs hardness of 5.5 to 6, and a specific gravity of 3.0.

Its name originates from the Greek Ίνες (ines), "fibers" in allusion to its color and habit.

[3] Inesite occurs in hydrothermal replacement deposits of manganese-rich metamorphic rocks and serpentines.
