Polished meteorite: Cutting and polishing an iron meteorite usually reveals a fantastic pattern of metal crystals inside. Known as a “Widmanstatten pattern,” these crystal shapes are natural art that many people appreciate. Cut and polished meteorites are used to make cabochons, pendants, beads, watch faces, rings, and many other items. The piece in the photo above is a guitar pick. Imagine making music with a piece of the core of an extraterrestrial body!
