This collection brings together 578 minerals from across the natural world. The selection includes well-known examples alongside rarer specimens that many people never encounter.

Minerals are naturally occurring solid substances with a defined chemical composition and an ordered internal structure. They form through geological processes such as cooling magma, evaporating water, or pressure deep within the Earth. The variety is remarkable, ranging from common rock-forming types like quartz and feldspar to rare gemstones and metallic ores. Minerals matter in everyday life because they supply raw materials for construction, electronics, jewelry, and countless industrial products.
