At least 10 small Kyanite blades permeate the quartz host rock of this large thumbnail specimen. These blades do not exceed lengths of 2.3" (5.8 cm), but are generally in pristine condition, showing amazingly little damage for their exposure; most of them have natural, undamaged terminations! The triclinic blades have well-defined edges and clean faces that possess a pearly luster, and their color is a moderately pale royal blue. All are at least translucent, and many are dimly to moderately transparent. The quartz that acts as their matrix is formless, colorless, and transparent amidst its intense internal fracturing.
