Pegmatite is a coarse-grained igneous rock known for its large crystals, formed by slow-cooling magma rich in water and dissolved ions. Common minerals in pegmatite include quartz and feldspar, but it's also notable for containing rare minerals and gemstones like tourmaline, beryl, and spodumene. The high concentration of water allows for large crystals to form, creating valuable specimens for collectors and industrial materials such as mica and elements like tantalum, lithium, and niobium.

Key CharacteristicsCoarse-Grained:

Pegmatites are defined by their extremely large crystals, often several centimeters to meters in length, due to their slow cooling process.
