It is present in significant quantities in the ore minerals monazite and basnasite . Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. Although neodymium is classed as a "rare earth", it is a fairly common element. The color of neodymium compounds—due to the Nd3+ ion—is often a reddish-purple but it changes with the type of lighting.
