Minerals are made of elements (these are the tiny building blocks of non-living things) arranged in a specific way. The specific way that elements are arranged in minerals makes regular shapes, a bit like scaffolding around a building. These regular shapes are called crystals.
Minerals are naturally occurring (not made by humans), inorganic (not alive) and solid (not liquid, like water or gas, like air). To learn more about minerals, and how they are like cakes (!) visit our learning zone.
A mineral is different from a rock; a rock is made of more than one mineral.
How does diamond look?
The crystals in minerals make different shapes, depending on which elements are making up that mineral. For example, diamond is a mineral, made of the element carbon. The carbons all connect to four other carbons, making a regular shape, as seen in the picture.
