Double Pyrite Cube

 At first glance some people think that these pyrite cubes are man-made, but the amazing thing is that they are completely natural! Pyrite from the "Ampliación a Victoria" mine near Navajún, Spain is famous for its beautiful shine, near-perfect cubic formation, and sculptural appearance. A must have for any mineral collector!
