Epidote Specimens
Epidote is a calcium aluminium iron sorosilicate mineral which crystallizes in a monoclinic system.
Well-developed crystals are of frequent occurrence: they are commonly prismatic in habit, the direction of elongation being
perpendicular to the single plane of symmetry. The faces are often deeply striated and crystals are often twinned. Many of
the characters of the mineral vary with the amount of iron present for instance, the color, the optical constants, and the
specific gravity. The color is green, grey, brown or nearly black, but usually a characteristic shade of yellowish-green or
pistachio-green. The name is derived from the Greek word "epidosis" (επίδοσις)
which means "addition."
