Kyanite is an aluminum silicate mineral that's notoriously difficult to facet because of its perfect cleavage and variable hardness, even within the same crystal. When cut parallel to its (long) c-axis, it has a hardness of 4 to 4.5. When cut perpendicular to its c-axis, it has a hardness of 6 to 7.5.
