Undamaged grouping of tan colored calcite crystals projecting prominently from a matrix which is covered with a first generation of smaller white calcite crystals. The top crystal is twinned. An unusual locality for me in that it comes from Gralex Quarry, Mont-sur-Marchienne, Charleroi, Hainaut Province, Belgium.
