Bastnäsite
Bastnaesite is the name for a group of minerals that belong to the carbonates and nitrates. They contain metals called rare earths, e.g. cerium, lanthanum, neodymium and yttrium. Natural deposits always contain two or more rare earths due to the formation of solid solutions. Bastnaesites are mainly used for the extraction of rare earths, only particularly clear and beautiful specimens are processed into gemstones. The name comes from an ore mine near Bastnäs in Sweden, where in 1838 a bastnaesite was found for the first time and named after its origin by a mineralogist.
