Named for the Greek beryllos, now meaning “beryl,” but previously used in reference to antiquated blue-green stones which may or may not have been Beryl. Beryl is a common mineral that occurs in granite, granite pegmatites, nepheline syenite, mafic metamorphic rocks, hydrothermal veins, and in vugs in rhyolite. Thousands of localities but fine specimens come from localities in Russia, Ukraine, Mozambique, Madagascar, Nigeria, Zimbabwe, Colombia, Brazil, Pakistan, Afghanistan, and the United States. Minerals associated with Beryl include quartz, feldspar, muscovite, lepidolite, spodumene, amblygonite, tourmaline, topaz, cassiterite, columbite, and tantalite. Popular varieties of Beryl that are prized for gemstones are Emerald, Aquamarine, and Morganite.

Named for the composition of mainly beryllium. Beryllonite is a rare mineral that occurs as a secondary mineral in granitic and alkalic pegmatites. Localities include in the United States, Canada, Finland, Sweden, England, Afghanistan, and Brazil among a few others. Associated minerals include herderite, triplite, beryl, apatite, cassiterite, columbite, eosphorite, morinite, vayrynenite, lithiophilite, Elbaite, pollucite, Petalite, lepidolite, albite, orthoclase, quartz.

Named in honor of noted Swedish chemist and mineralogist Jons Jacob Berzelius, who discovered the element selenium which is an important component of the mineral. A rare but wide spread mineral that occurs in localities in Sweden, Germany, the Czech Republic, Uzbekistan, Argentina, Brazil, Sumatra, Australia, Canada, and the United States. It can be found in occurrence with other selenides in hydrothermal veins and calcite veins, and in gold-quartz deposits. Associated with eucairite, clausthalite, tiemannite, umangite, klockmannite, aguilarite, crookesite, athabascaite, stromeyerite, polybasite, pearceite, gold, uraninite, pyrite, marcasite, and calcite.

Named in honor of noted Swedish chemist and mineralogist Jons Jacob Berzelius. A rare mineral that occurs in metamorphosed iron-manganese orebodies in localities in Sweden, Switzerland, Italy, Kazakhstan, and Venezuela. Minerals associated with Berzeliite include hausmannite, rhodonite, tephroite, hedyphane, caryinite, manganoan biotite, langbanite, braunite, dolomite, barite, and calcite.
