This specimen displays very well from the side in a couple of different angles. It has a deep cavity in the front of it that has many of sharp, ruby red proustite crystals in it. Also in the main cavity and many other openings in the specimen are xanthoconite crystals and arsenopyrite crystals. The xanthoconite crystals are fantastically, well shaped, orange-yellow, terminated, tabular crystals which are smaller than the biggest, prismatic proustites. Excellent!
