Learn about... Minerals

A mineral is defined as any naturally occurring, inorganic solid substance with a more-or-less definite chemical composition and physical properties. Rocks are made up of different minerals, and each mineral contains one or more chemical element, such as sodium, calcium or iron.

Minerals are usually found in crystalline form, which reflects the way the atoms are arranged. If allowed to grow freely, these crystals form geometrically perfect, regular shapes.
