This Kyanite specimen is an example of a relatively new find in Brazil, that of black Kyanite. It occurs as a spray of long, thin crystals that branch out along one plane. Some of these crystals reach up to 3" (7.5 cm) in length, and none exceed 0.2" (5 mm) in width or depth. They have a black color and a dull pearly to waxy luster. There is noticeable damage in the form of broken crystals, but most of them have indistinct terminations, anyway, so their form is moderately good. There is no host rock of any sort associated with the specimen, and it should be handled with care due to the exposure and delicacy of the crystals.
