A difficult subject to photo since the dark green Epidote competes with the platy Calcite for the light. It is an interesting specimen in that the Calcite forms thin colorless plates to over 1cm with divergent sprays of dark green Epidote to 8mm. With the Epidote and Calcite are tiny cubes of Pyrite. In the matrix is brownish yellow Prehnite.
