The Kyanite crystals on this specimen are so tightly clustered that I cannot effectively count them. They reach a maximum length of about 2.0" (5 cm) and are generally in good condition, though many of them are damaged and incomplete. Those that are intact, though, tend to have excellent triclinic bladed form- many show intact and complete natural terminations (see the close-up image). All have a color that ranges from a pale to moderately deep blue and a bright pearly luster. Most show some reasonable transparence and clarity, though often the thicker blades are essentially translucent due to internal fractures and inclusions. The white quartz matrix rock in which they rest is somewhat crystalline in nature but has no form.
