Member of:
Named in 1978 by Chao et al. in honor of Joseph Désiré Hubert Donnay (6 June 1902, Oreye, Liège province, Belgium - 8 August 1994, Mont Saint Hilaire, Quebec, Canada), Professor of Mineralogy and Crystallography, Johns Hopkins University, Baltimore, U.S.A. and his wife Gabrielle (Gai) Donnay-Hamburger (1920, Landeshut, Silesi, Germany (now Poland) - 4 April 1987, Mont St. Hilaire, Quebec, Canada), Professor of Crystallography, McGill University, Montréal, Canada, for their significant contributions to crystallography. He was awarded the 1971 Roebling medal. She is known for solving the complex structure of tourmaline, and later solved numerous other structures.
Two polytypes are known, donnayite-(Y)-1A and donnayite-(Y)-3R.

The UM1992-05-CO:CaCeLaNaSr phase, although suggested to be polymorphous with donnayite-(Y), slightly differs in terms of chemistry.
