This specimen consists of two partly intersecting sprays of Kyanite needles. The larger spray makes up most of the mass of the piece and contains crystals that attain lengths of up to 3.6" (9.1 cm). The smaller spray has general dimesions of 2.2 x 0.5 x 0.4" (5.6 x 1.3 x 1.0 cm). Both show heavy surface damage- most of the crystals on the outside of the sprays are broken or badly damaged. Those that are away from the surface, however, are in very good condition and usually possess intact terminations. Their triclinic form, where intact, is very good- edges are well-defined and faces are clean, possessing the standard pearly luster. These crystals have a black coloration, which has only recently been found in Brazil. They are, needless to say, opaque. There is no host rock present on the piece.
