Almost Perfect Cubes Formed in Nature

These amazing pyrite crystal specimens are found in Navajún, La Rioja, Spain. Believe it or not, these cubes have not been cut or polished to shape. They are found just like this within the marl matrix.

Speaking of fools, I was about nine and we had gone to Georgia for vacation. We stopped at this mineral deposit with a water sluice for screening the dirt for gems. I found a chunk of pyrite, went to bite it like they do in movies and cracked a tooth. r/kidsarefuckingstupid

I did this to a gold locket I was given as a kid. First thing I did was bite it! Still have it and it still has a big dent in it!
