Hematite crystals typically form in the trigonal system and can exhibit a variety of habits, including tabular, elongated prismatic, and subparallel aggregates. The crystals are usually opaque and have a metallic luster, appearing in shades of metallic gray, black, or silver. Hematite crystals can also display striations on their surfaces and often have a distinctive reddish-brown streak when scratched on a rough surface. Due to its strong iron content, hematite is attracted to magnets, exhibiting weak ferromagnetic properties. These crystals are commonly found in sedimentary, metamorphic, and hydrothermal settings around the world.
