This small thumbnail specimen consists of at least 3 Spinel octahedrons that are partly embedded in a white pegmatite base. Two of these octahedrons are partly intergrown, whereas the third (and largest) is isolated. The smaller crystals do not exceed 0.1" (3 mm) in diameter, but the larger one measures 0.3 - 0.4" (8 - 10 mm) in diameter. However, this large crystal is only about 60 - 70% complete and shows slight but visible damage, whereas the smaller crystals, apart from their intergrowth, are essentially complete and undamaged. Their octahedral form is generally very good, with well-defined edges and clean faces that possess a pearly luster. All have a dull, deep violet coloration. The larger crystal is generally dimly translucent, showing small areas of transparence, whereas the smaller crystals are dimly transparent under bright light. They are accompanied by a few broken, pseudohexagonal muscovite books. The piece is attached to a small acrylic base with a removable putty.
