A partly intergrown "stack" of Kyanite blades makes up this hand specimen. These blades range in length from 3.8 - 6.1" (9.7 - 15.5 cm) and are all generally 1" (2.5 cm) wide. Damage is limited to the base of the crystals, where they were separated from their place of formation, and the tip of the termination of the longest crystal- otherwise, all of the blades are in excellent condition. Their triclinic form is surprisingly good, as all of the blades appear to have intact, natural terminations (except for the longest blade, of course). They have the standard uneven royal blue coloration and pearly luster of this mineral, and show translucence or transparence only where portions of individual crystals are exposed- otherwise, they are opaque. The only evidence of a host rock that is present are a few bits of colorless massive quartz that are wedged between the Kyanite terminations and a small bit of crust that coats part of one side of the specimen.
