Dozens of Kyanite blades pervade the massive quartz host rock of this hand specimen. Most of these appear to be damaged or broken, but a few are in excellent condition, showing no damage. The longest of these crystals are concentrated in a radiating spray and reach lengths of up to 4.1" (10.4 cm). Though not parallel, all are aligned with each other so that they share a common base and extend outwards, their terminations buried in the base rock. Their form is very good, with well-defined edges and relatively clean faces that possess a pearly luster. All have the uneven, pale to moderate royal-blue coloration that is standard for this mineral, and most of the smaller crystals are either translucent or transparent, though the spray of larger crystals is essentially opaque. The massive quartz base is amorphous, translucent, and has a generally milky-white coloration due to intense internal fracturing. Small areas are colorless and transparent, however.
