There are two sharp pseudomorphs of ankerite after sodalite on this specimen. The one on the top of the specimen is a complete, well formed dodecahedron. The one on the right that is a more complex isometric form combination is only partially visible. The rest of the piece is composed of rounded aggregates of ankerite or siderite crystals. Interestingly, on the back of the piece, you can look into the bigger pseudomorph. It is hollow! Displays well.
