Hematite is a dark gray to black mineral known to various cultures throughout history. Babylonians, Egyptians, Greeks, and Romans were a few of the civilizations that made use of this mineral. Hematite derives its name from a Greek word for blood, an allusion to the reddish powder produced during the fashioning process due to the presence of iron.
