Located in the Aracuai pegmatite district of Minas Gerais, Brazil, Coronel Murta is a world-renowned pegmatite locality famous for its rich lithium and boron-bearing granitic pegmatites emplaced within Precambrian metamorphic rocks during regional tectonic events. These complex zoned pegmatites formed through deep-seated magmatic crystallization and hydrothermal fluid activity that concentrated rare elements in open cavities. The area has a long history of artisanal and commercial pegmatite mining targeting high-grade gemstone and mineral specimens. It is especially celebrated by collectors and museums worldwide for producing exceptional crystals of elbaite, a complex cyclosilicate mineral of the tourmaline group, frequently displaying striking multicolored zoning, such as vibrant green and pink crystals, alongside other accessory pegmatite minerals.
