A large cabinet specimen with a fan-shaped spray of calcite sharing a matrix with numerous small iridescent chalcopyrite crystals.  It is better in person, my photography set up is not intended for pieces of this size.  

The calcites contain faint phantoms, and the chalcopyrite is more iridescent in person.

The only damage to the piece is a cleave on one of the terminations making up the spray (left side).  The price more than takes this into account-- it would have easily been a $2,500 piece without that one imperfectoin.
