Pegmatite's crystallization process often causes the concentration and enrichment of rare ore minerals, including lithium, beryllium, tantalum, and many others. These minerals are of great economic interest and have a wide range of industrial, technological, and scientific applications. Pegmatite is also a major source of gemstones, such as beryl and tourmaline, which are highly prized for their beauty and rarity.
