The form of the two Brazilianite crystals in this specimen is quite unusual. They constitute the entire specimen- one measures about 1"(2.5 cm) in length, and the other about 3/4"(1.9 cm). They have a pale yellow color with a hint of green and are transparent but heavily internally-fractured. They have a pearly to vitreous luster and occur in pseudotetragonal prismatic crystals with steep angled terminations. However, the two temination faces on each crystal have bizarre "hopper"-like formations that resemble "skeletal crystals". I don't know if this is a common occurrence for this mineral. Also, the smaller of the two crystals is double-terminated, although the second termination is missing its tip. The specimen is glued into a plastic specimen box. It is a piece that I want to spend "too much time" studying.
