A large, double terminated Quartz crystal reminiscent of a Herkimer Diamond. In several places. the color is darkest just below the surface forming zonal lines within the specimen. The upper layers of the crystal are generally transparent. In places, there are sparkly veils a little below the surface and in other places, prismatic, rainbow diffractions. Attached to the bottom of the crystal, there is some minor Dolomite with small cubic Pyrite crystals. On the bottom of the crystal, there are a number of bladed Marcasite crystals which have pseudomorphed to Pyrite and exhibit a bit of iridescence. The Quartz crystal had grown over these and with the exception of a couple, these crystals have snapped off.
Flaws: There is slight chipping on some of the edges and corners. Nothing very noticable.
