This lovely specimen is consists of a cluster of sharp, triangular Colemanite blades. These bladed crystals are in generally good condition, though several are damaged, and a few severely so. They have maximum dimensions of 1.4 x 1.1 x 0.3" (3.6 x 2.8 x 0.8 cm) and show excellent monoclinic form, with sharp edges and smooth faces that have a bright, pearly-to-vitreous luster. Individual blades are colorless and transparent, though their clarity is often spoiled by their intergrowth. There is no host rock present, and the intergrown bases of the crystals hold them together.
