A superb, unusually euhedral single crystal of catapleite, measuring 2.2 cm across, nestled in matrix of other MSH minerals including aegirine and pectolite, and perhaps kupletskite (on the back). Isolated single crystals of catapleite, of this size, are fairly rare compared to the more common muscovite-looking style we often see. 4 x 3 x 2.75 cm
