Alluaivite is an exceedingly rare mineral of the eudialyte group, with complex formula written as Na19(Ca,Mn)6(Ti,Nb)3Si26O74Cl·2H2O. It is quite unique even among the eudialyte group to be a titanosilicate (other representatives of the group are usually zirconosilicates). It is named after Mt. Alluaiv in Lovozero Tundry massif, Kola Peninsula, Russia, where it is found in ultra-agpaitic, hyperalkaline pegmatites.[1][2][3]
