A mirror bright, lustrous, brassy yellow cube of pyrite, to 4.0 cm across acts as a host for a smaller crystal of the same species which is obliquely, and aesthetically, perched on the larger crystal. Common material, but still and all one of the most amazing minerals in the world for its ability to impress layment with the stark symmetry (that so few outsiders believe us about, when we say it is natural!). A common mineral and locality, but a very nice example, here.
