Hematite

Hematite is an interesting form of mineral primarily composed of iron oxide, which gives it its typical gray to black color and metallic luster. It is distinguished by its rounded and knobby formations, which develop through a crystallization process under specific conditions. Commonly found in sedimentary layers and hydrothermal veins, hematite is widely distributed throughout the world but particularly abundant in Europe and Asia.
