Rareearth elements (REE) are frequently divided into "light" and "heavy" rare earths or LREE and HREE. Definitions of LREE and HREE can vary, but generally Gd and the lighter REE (, La, Ce, Pr, Nd, Sm, Eu, and Gd) are taken as the LREE, and the other REE, including Y, are deemed to be the HREE. REE assays and prices are often expressed on the basis of the .
