Formula: PbFe3+3AsO4(AsO3OH)(OH)6

Habit: individual rhombohedra; rosette-type isometric aggregates with short-rhombohedral crystals; isometric aggregates with long-prismatic crystals ending with sharp rhombohedron; open-work or flattened aggregates of long-prismatic crystals. Hexagonal prism, sharp rhombohedra (positive and negative) and pinacoid faces are developed in all the aggregates. One can observe sectorial zonal growth with clearly different morphology on the faces of the positive and negative rhombohedra under high magnification. The crystal size varies from 0.1 to 5 mm, among the biggest in the world for this mineral. The size of the aggregates varies from 1–2 to 5–10 mm, sometimes the mineral forms crusts, several millimeters thick.

Colour: yellowish green to dark oily green

Description: Discovered in October 2009, in the barite ore body (NE part of the open pit), level 508 of the Kremikovtsi deposit.
