Dozens of triangular Colemanite blades are intergrown to make up this hand-sized specimen. According to the included documentation, they are of a form known as shark's teeth, due to their flat, triangular form. The specimen is generally in good condition, though there are several crystals that are obviously damaged and broken. Their form is quite good, with sharp edges and clean faces that possess a dull pearly-to-waxy luster. All are colorless as individuals, but have a generally milky white coloration in their cluster. Each crystal is transparent and dimly to moderately clear, though all contain some cloudy inclusions and are considerably internally fractured; these internal fractures reflect light with an unusually bright luster that makes me think of those found in apophyllite crystals. There is no host rock present- the entire specimen is made up of either crystalline or massive Colemanite.
