The largest crystal is 9x6mm, most of the other crystals are between 1 to 3mm. All of the Chalcocite crystals are well-defined but a bit unusual as they are not your classic shape for Chalcocite. Chris van Laer was a little hesitant to call these Chalcocite. The matrix is composed of micro Pyrite with some dull black blebs of Tennantite(?).
