A cluster of Cassiterite crystals partly covers the pale brown host rock of this small hand specimen. These crystals are in generally good condition, though several are obviously damaged or broken. They reach dimensions of 0.6 x 0.4 x 0.3" (1.5 x 1.0 x 0.8 cm) and show reasonably good tetragonal form, though individual crystals are nearly impossible to define due to their intense twinning and intergrowth with each other and the quartz crust on which they rest. Each crystal has well-defined edges and clean faces that possess the standard adamantine luster, however. All have a brown color that deepens as the crystal's size increases. Thus, several of the smallest crystals are noticeably transparent, whereas the largest ones are essentially opaque. They rest on a quartz crust out of which extend several hexagonal prismatic crystals, several of which are damaged. This crust in turn coats the host rock, which I cannot identify.
