The name hematite comes from the Greek word for blood. The hematite is black, but when powdered or fragmented can take colors ranging from ochre red to jet black. An opaque mineral with a dull lustre, it has been known as "black diamond". Historically it was used in the making and coloration of pottery. It was also made into a paste from which beads were made and hardened, and appears commonly today as black beads in costume jewelry. 磁铁矿的名字来源于希腊语中的‘血’。这种矿物呈黑色，但被粉碎或研磨成粉末时，其颜色可从橙红色到黑色变化。它是一种不透明的矿物，具有暗淡的光泽，曾被称为‘黑钻石’。历史上它曾用于陶器的制作和着色。它还可被制成糊状物，用来制作珠子并使其硬化，如今常见于服装珠宝中的黑色珠子。
The oxide mineral hematite is the major ore of iron. Hematite with this rounded shape is called kidney ore. 氧化矿石赤铁矿是铁的主要矿石。这种呈圆形的赤铁矿称为肾形矿。
