This piece consists primarily of a single, round cluster of radiating Stellerite crystals that rests on a thin white crust. The cluster essentially makes up the entire piece, and the crystals that it contains do not exceed 0.4" (1.0 cm) in length. All are in excellent condition but are so intergrown that they are impossible to study as individuals. Several tiny Stellerite crystals are gathered at the base of the cluster- these show excellent orthorhombic prismatic form, with well-defined edges and striated but clean faces that possess a bright pearly-to-vitreous luster. The cluster has the deep orange coloration that is common for this mineral, and the small, individual crystals have a paler orange coloration. All are translucent to dimly transparent, though again, the smaller crystals are essentially clearer than the cluster. The Stellerite appears to be accompanied by many chabazite crystals, most of which are broken or incomplete, and the thin white crust on which they rest appears to be made of calcite.
