TC220MF: Parallel growths of Quartz crystals with dipyramidal habit and scepter terminations. Some of the crystals apparently lack prism faces, which has sometimes led to the erroneous belief that they are β-Quartz. The crystals, rich in inclusions, are partially covered by small white Calcite-Dolomite crystals.
