Glucine occurs as 10-50 micron sized needles and platy crystals (Mindat). Localities

At the type locality, the Boevskoe Be deposit (Boevka; Severnoye), Kaslinsky District, Chelyabinsk Oblast, Russia, glucine occurs as segregations in mica-fluorite greisen in illite rocks. Associated minerals include moraesite, fluorite, rutile, limonite, quartz and mica-clay minerals (HOM).
