Hematite, the common iron ore, invariably has a red-brown streak. Some minerals are very soft; others very hard. The degree of hardness is an aid in identifying the minerals. Diamonds are harder than quartz and will therefore scratch quartz, quartz will scratch calcite, calcite will scratch gypsum, and so on.
