Gem-quality minerals such as emerald, ruby, sapphire, aquamarine, garnet, and amethyst have been found recently in Somaliland. The majority of the gemstones are derived from pegmatitic host rocks related to late granite intrusions within the Mozambique orogenic belt, which extends through the centre of Somaliland in an east-west zone. Where pegmatites cross-cut biotite and amphibole schists, emeralds may occur, whereas aquamarines are more common when pegmatites intersect migmatites and granite gneisses. Not all reported gemstones have been collected from known production sites, and minerals such as rubies, sapphires, opal, and pyrope or almandine garnet likely originate from a variety of rock types. Most gemstones are extracted from solid, unweathered rock using rudimentary recovery methods. The importance of gemstones in the Mozambique orogenic belt has already been recognized in Kenya, Tanzania, Sri Lanka, India, and Madagascar. The identification of this belt’s extension into Somaliland is therefore of considerable significance, suggesting untapped potential for a wide range of gemstone production, which remains to be fully assessed.
