Though I classified this particular specimen under "Kulanite", it was not an easy decision. There are dozens of the black, bladed crystals, including one extremely large(0.4 x 0.3" or 1.0 x 0.8 cm) "crystal" made up of intergrown blades. All are opaque and have a bright, vitreous luster that makes them sparkle. They are surrounded by a large number of siderite crystals that have extraordinary size and form. These crystals range from less than 1 x 1 mm to 10 x 6 mm in respective length and diameter, and occur in a trigonal prismatic form akin to the scalenohedral "dogtooth", but have flat, triangular basal terminations. The smaller ones are a pale brown in color that deepens as the crystals' size increases, and are transparent to translucent, which is also respective to size. There is no host rock to speak of, and the specimen is hot-glued to an acrylic base for display.
