Calcite pseudomorph after Glauberite with sharp, excellent, crystals with some of the best preserved forms I have seen of these specimens. Usually these are broken or scuffed up, but not this specimen. It is nearly perfect with no damage at all. It was purchased by Hampson in 1967.

They called this stuff "pepper" cassiterite for its resemblance of pepper in rock. This particular piece shows plenty of tetragonal octahedrons to 2mm. The White Cap mine is one of the better localities for Cassiterite in the Black Hills.

This was a tough one to photo. It looks so much better in hand. The largest crystal is 4cm and there are two large groups in the center surrounded by smaller crystals. No damaged, very fine specimen on a matrix of Sulphur amd limestone.
