A member of the Tourmaline Group, Elbaite is named for the type locality at Fonte del Prete on Elba Island in Tuscany, Italy. Relatively common, Elbaite can be found of exceptional quality at its type locality, and in localities in Russia, Afghanistan, Pakistan, Madagascar, Mozambique, Namibia, the United States, and Brazil, among many other localities. It occurs in granite, granite pegmatite, metamorphic rocks, high-temperature hydrothermal veins, and as a detrital mineral in sediments. Elbaite is pyroelectric, generates a charge in response to heat, and piezoelectric, generates a charge in response to pressure.

Named for the type locality in St. Peters Dome in the Cheyenne district of El Paso (Elpaso) County in Colorado, USA. Elpasolite is a rare mineral that can be found in additional USA localities as well as in Italy, Greenland, Ukraine, Russia, and the Democratic Republic of the Congo. Elpasoite occurs as a replacement for fluorine minerals in quartz-microcline pegmatites and in quartz veins associated with hydrothermal antimony deposits in silicon rich limestone.

Named for John Ely, a promoter of an early mining company from Nevada, USA and frontiersman. Elyite is an uncommon mineral that forms in oxidized portions of base metal sulfides as well as in dumps and slags. It can be found in localities in the United States, Germany, Japan, Namibia, England, Scotland, Wales, and others. Minerals associated with Elyite include galena, langite, serpierite, cerussite, anglesite, lithargite, and minium.
