yes

Don't forget to try pyrite (also known as "fool’s gold", made of iron and sulfur), cobaltite, zincite, arsenopyrite, skutterudites, obsidian (also known as Apache Tears) and others.

Thirdly, pyrrhotite is magnetic or at least weakly so. It is the next most common magnetic mineral to magnetite. Although not all specimens will show great evidence of magnetism if any, some will attract a paperclip or needle suspended from a string or move the needle of a compass. Massive pyrrhotite is common and magnetism is sometimes the only way to distinguish it from other brassy colored sulfides such as chalcopyrite, pyrite, pentlandite or marcasite Good crystals are rare and should rightly be treasured as comming from a very unusual mineral.

Other Characteristics: weakly magnetic, prism faces striated parallel to pinacoid faces and color will darken with exposure to light.
