This small Spinel specimen confuses me a bit. It consists of at least 2 Spinel crystals that are rather heavily intergrown. The larger crystal appears to be slightly damaged and not quite complete, though the smaller one does not show any visible damage. The larger crystal has visible dimensions of 0.3 x 0.3 x 0.2" (8 x 8 x 5 mm), whereas the smaller crystal does not exceed 0.1" (3 mm) in any dimension. Their form is quite odd- it certainly is not octahedral, and does not even appear to be cubic- I cannot define it properly! However, they still have well-defined edges and striated but clean faces that possess a bright pearly luster. Both crystals are colored black and are essentially opaque. The Spinels are accompanied by many rounded muscovite "books" that have a golden-brown coloration and a bright pearly luster. All are embedded in a white, crystalline pegmatite host rock.
