MG37AA7: Quartz with inclusions Chlorite, Calcite-Dolomite and Magnetite

Divergent Quartz crystals with dipyramidal-shaped sceptered terminations, and with Chlorite inclusions. They are on matrix, with Magnetite and Calcite-Dolomite. Some of the crystals have no prism faces and such crystals have sometimes been erroneously described as β-Quartz.
