Epidote is fairly dense, fragile with distinct cleavage and is rarely cut as a gemstone. Epidote crystals are yellow, green, or dark brown columnar prisms, with faces finely striated parallel to the crystal's length. Pleochroism is strong, showing either yellow, green, or brown. Rock composed mainly of epidote may be polished or tumbled and sold as unakite.
Dark green crystals occur in the Austrian and French Alps. Epidote is also found in the former USSR, Italy, the island of Elba (Italy), Mozambique and Mexico.
