Sections of at least 10 different Kyanite crystals are held together by the white quartz host rock of this specimen. The largest of these crystals has dimensions of 4.0 x 0.6 x 0.1" (10.2 x 1.5 x 0.3 cm) and shows what I believe are natural, flat basal terminations. All of these crystals have the moderate, royal- to sky-blue color that one expects of this mineral and are translucent, showing small areas of dim transparence. Their pearly, micaceous luster is also a standard for Kyanite, and is quite evident. The quartz host shows no detectable crystal form, which is also expected of specimens from its Brazilian locality.
