Tephroite, Caryopilite - Sold

Tephroite is a manganese silicate member of the olivine group. The mineral name come from From the Greek for ash-colored (Breithaupt, 1832). Tephroite here forms sparse sharp crystals to 3-4 mm scattered over boxwork caryopilite. Caryopilite is a hydrated manganese silicate named after the Greek words for walnut and felt (Hamberg, 1889), which aptly describes its color and texture in this specimen.
