Uramphite is a rarely-found phosphate mineral in the "phosphate, arsenate and vanadate" mineral class with chemical composition (NH4)2[UO2PO4]2·6H2O from which it is seen to be a hydrated ammonium uranyl phosphate.
Uramphite crystallizes in the tetragonal crystal system and develops rectangular crystal faces approximately 0.2 mm wide, but is also found as rosette-like mineral aggregates and surface films. The mineral is translucent a colored light to bottle-green or light yellow with a shiny lustre on the exterior.
