Four Kyanite crystals intersect to form this large cabinet piece. The largest of these crystals is by far the most complete, measuring 6.9 x 0.9 x 0.8" (17.5 x 2.3 x 2.0 cm); the others are half that length or smaller, and are all incomplete. All have reasonably good triclinic form, however, and the largest crystal is essentially complete and reasonably well-formed. All have the standard blue color and pearly luster and are opaque, though one area does show some dim translucence. There is no host rock present.
