This specimen consists of a shapeless chunk of crystalline Eudialyte that is attached to a piece of compact, fibrous agrellite. The Eudialyte is heavily broken- no evidence of crystal form is present- and all edges and surfaces are rough and uneven. The material has the classic deep red-violet color of its species and a bright pearly-to-vitreous luster. The agrellite, a sodium calcium silicate fluoride, has a pale, gray-white color and a rather silky luster due to its fibrous habit.
