Pyrite beads are a feature of the latest jewelry trends. However, as with any type of jewelry, it is important for buyers to know what they are looking for before they make a purchase. Pyrite is also known as "rock pyrite" or "marcasite". In addition, it may also be called chalcopyrite, pyrrhotite, or sphalerite. It contains copper and iron in different amounts that give you different colors of pyrite beads.
