An interesting find from Inner Mongolia, though one that involves a bit of creative cleaning.  Most of the quartz specimens from this discovery were just clusters of small crystals, resembling the Brazilian amethysts, but without the color.  Some however had larger quartz crystals that have been overgrown by a second generation of quartz. There was sometimes some space between the main quartz crystal and the secondary generation, and cleaning/trimming left them with these little stems.
