This specimen displays several intergrown cubic crystals of cobaltite in a matrix that appears to be a plagioclase feldspar. The largest of the cobaltite crystals is retangular rather than a cube, and is missing one corner but it appears to be a growth pattern showing striations, and not damage. The other crystals are progressively smaller cubes. All have a bright silvery metallic appearance, somewhat reminiscent of galena. There is a network of fine cracks in the largest crystal, which is missing a tiny bit of one corner (damage). The next smaller crystal is missing quite a bit of one corner, exposing the uneven fracture of cobaltite.
