Hibonite chrysoberyl The crystal was apparently attachedWe were able to acquire a large lot of excellent crystals of this rare mineral. The partially hexagonal crystals are mostly completely black and exhibit an attractive star shaped luster reflection on the crystal faces, reminiscent of trapiche crystals. A fascinating specimen, with clearly visible edges, layering, and a hexagonal habit. Also, a very beautiful star reflection.
