The dark brownish-green color or pistachio-green color of epidote is characteristic of the mineral and gives the mineral its’ alternative name – pistacite. Closely related to zoisite which is orthorhombic, epidote is a calcium aluminum silicate with some iron, Ca2(Fe,Al) 3(SiO4)3(OH). The mineral crystallizes in the monoclinic system with vertically striated crystals that seldom display distinct terminations. Epidote is strongly pleochroic the colors being green, brown, and yellow. Epidote is a fairly common mineral and is found at many places in the alps.
