One predominant, razor-sharp, highly lustrous, fine bluish purple octahedron of Spinel, along with some secondary less pronounced crystals sit atop a white marble matrix with some minor associated rich orange color Chondrodite on the reverse side of the specimen. The main crystal, which measures 8 mm across, is about as sharp and lustrous that I have seen from Afghanistan. Despite a few small tool marks to the matrix, this is a nice reference specimen.
