Order in the Triclinic System: In designating forms in the Triclinic System, most crystallographers use 1st through 4th order labels. 1st, 2nd, and 3rd order labels are applied to pinacoids that intercept two of the axes and are parallel to the third axis. 1st order denotes forms parallel to the a-axis. 2nd order is parallel to the b-axis. 3rd order is parallel to the c-axis.

Kyanite has a hardness from 4 ½ - 7 on the Mohs scale and has perfect cleavage. For the lapidary (stone cutter), this poses a real challenge.
