Our next step will be learning a bit about the individual minerals that make up the various rocks. The following question gives us a good start.
Hello. On a recent visit to a museum I came across a crystal called pyrite. I was, and still am astonished by the perfect cubes formed by the pyrite and I'm curious to know how it is possible for a crystal to form a shape as perfectly symmetrical and precise as a cube? I've been doing some searches on Google but I am unable to find any solid answers.
