A few broken Carletonite crystals make up most of the mass of this small thumbnail piece. These crystals are only in fair condition and measure less than 0.5" (1.3 cm) along their longest edges. All have good but incomplete tetragonal form and have a color that ranges from colorless to a moderately pale blue. Their luster is pearly and they are transparent but only dimly clear due to internal fracturing. A cluster of tiny aegirine crystals accompanies them, and the piece is attached inside a plastic specimen box with an easily removable putty.
