Abundant tourmaline crystals - mostly
black and many incomplete - cover all faces of a matrix
composed of tiny microcline crystals. These tourmalines
reach about 1.3 in length. A single 1.4 cm quartz crystal
is also seen. The matrix is curved, and its overall shape
hints that it may be a pseudomorph after spodumene.
