A sizable hand specimen, this piece consists of at least 16 Kyanite blades that are partially embedded in a massive quartz matrix. Their dimensions vary considerably, but the longest of them measures 4.4" (11.2 cm). Many of them show fresh damage, but some are either intact, with terminations that look somewhat weathered, or were damaged well before the specimen was mined, and then slightly worn or healed over. Their triclinic bladed form is reasonably good, and all of the crystals have the pale-to-moderate blue color and pearly, micaceous luster that are standard for this mineral. All are translucent and heavily internally-fractured, though some of the crystals show some patches of shallow transparence. The quartz base in which they are embedded is milky-white due to intense internal fracturing and shows no crystal form.
