Although this thumbnail specimen is incomplete, it is still a very nice octahedral crystal of betafite. The form is slightly modified in that several of the faces are stepped, either due to the way the crystal grew, or possibly because this is several intergrown crystals that are nearly aligned. Betafite is a black mineral, as is this, although it has a yellow earthy coating that is commonly found on weathered betafite crystals. Careful examination reveals several areas where the black betafite shows through the coating.
