An fine cluster of inter grown sphenoidal Chalcopyrite crystals measuring to 1.4cm, with a metallic brassy yellow colour, and striated crystal faces. A near central terminated Quartz crystal measuring to 7.2cm tall forms a dramatic feature to the specimen. The Quartz crystal is mostly gemmy clear with some milky areas, and with localised Chlorite inclusions. To one side of the specimen can be seen crystals of prismatic Quartz over grown by deep green Chlorite. A fine specimen from the St. Agnes mining area.
