    Gagarinite-(Ce) previously zajacite-(Ce) is a rare radioactive fluoride mineral with formula: NaF₆. REE refers to rare earth elements, mostly those belonging to the lanthanide series. It crystallizes in the trigonal - rhombohedral system and has a white vitreous appearance with a conchoidal fracture. It has a Mohs hardness of 3.5 and a specific gravity of 4.44 to 4.55. Zajacite is transparent with refractive indices of nω=1.483 and nε=1.503. Gagarinite- is a yttrium rich analog. It occurs as creamy to white anhedral to subhedral grains in pegmatite and aplite pods or lenses in a peralkaline igneous intrusion. It was discovered in 1993 at Strange Lake, Quebec - Labrador, and was initially named for Ihor Stephan Zajac, who led the expedition responsible for its discovery, and who first recognized the presence of the new mineral.
