Though not in a definite, isometric-based crystal form, this specimen shows more crystalline form and tendencies than any I have previously seen. It consists of a chunk of blue Sodalite with associated barite and ankerite, and has one cut surface. The surface of the Sodalite is divided up into many smaller, flat surfaces that are too flat and clean to be anything but crystalline. There is even one small surface that shows a definite angle which I belive indicates a twinning plane! It has the classic pale azure-blue coloration of its species, and is dimly translucent around its edges under normal light. Besides the barite and the ankerite, there is no other material present.
