Umbite is a hydrous potassium zirconium silicate. Khomyakov et al. (1983) named the mineral after Lake Umbozero, which separates the Khibiny and Lovozero Massifs.

Umbite forms bladed crystals in a cavity left by leaching a eudialyte crystal. The matrix consists of microcine and aegirine. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
