Minerals are the constituent materials of rocks and are most simple described as naturally occuring, inorganic substances.

The BRLSI's mineral collection was mostly gathered during the 19th Century and specimens were gathered from all around the world by a number of individual collectors.

The characteristic colours and crystal forms of each mineral result from their elemental composition and define atomic structure.
