Impressive, transparent glassy quartz with knife- sharp termination. The quartz is flawless in the top half or so and grades into a nice veily included base. The edge of the crystals has a thin but sharp zone of smoky gray that adds excellent visual appeal. A very high quality crystal in great condition. Mined c. late 1990s-2000. Dr. J. Gebel Collection.
