Pyrite natural form 

Pyrite’s name comes from the Greek, pyrites lithos, “the stone which strikes fire.” The crystals form in the Isometric System; cubes, octahedrons, pyritohedrons and combinations of these and other forms. It also may be found in radiating disks, hair-like crystals, concretions and massive lumps in sulphide ore deposits.

The Cinmar biface, found on the continental shelf near the Chesapeake Bay, suggests that the First Americans came from western Europe by boat some 16,000 years ago.
