So, by popular demand I am posting up one of the brand new awesome minerals! For starters, yes this is really how it looks. It's known as a pyrite cube and Spain is famous for having these great crystal structures where the pyrite mineral forms large cubes like this one. Pyrite is more commonly called Fool's Gold due to it's gold coloring. While they usually don't come in these pristine cube shapes, most pyrite specimens have a distinct cubic pattern if you look really closely. Sometimes you will find very cool Pyrite disks which look like gold sand-dollars, unfortunately the Sholesonian does not have one in the collection, yet.
