Several incomplete, heavily intergrown Carletonites make up this small thumbnail piece. These crystals are in moderately good condition, being rather broken, and reach nearly 0.6" (1.5 cm) in maximum length. Most show very good tetragonal form, though no terminations are present, and are colorless or pale blue and have pearly to vitreous luster. They are also translucent to transparent, primarily due to concentrated internal cleavage flaws. The piece is easily removed from its specimen box for study.
