This specimen was originally in the Ron Sohn Collection, a mineral dealer who was prominent in the 1960s through the late1970s and had retired by the early 1980s. The coverage of strontianite is nearly complete across the surface as aggregates of ball-like groups with characteristic curved terminations on the crystals. Calcite matrix is classic from this section of the mine. Really an excellent specimen and displays wonderfully well. Gail Hall collection RL 95-07. Mined c. early 1980s.
