Pumpellyite is a group of closely related sorosilicate minerals: pumpellyite-(Mg): pumpellyite-(Fe2+): pumpellyite-(Fe3+): pumpellyite-(Mn2+): pumpellyite-(Al):

Pumpellyite crystallizes in the monoclinic-prismatic crystal system. It typically occurs as blue-green to olive green fibrous to lamellar masses. It is translucent and glassy with a Mohs hardness of 5.5 and a specific gravity of 3.2. It has refractive indices of nα=1.674–1.748, nβ=1.675–1.754 and nγ=1.688–1.764.
