A single "Herkimer Diamond" quartz crystal rests in the sizable host rock of this hand specimen. It is in excellent condition, showing no visible damage, and has a diameter that averages 0.4 - 0.5" (1.0 - 1.3 cm) and a length that likely reaches 0.7" (1.8 cm), though not all of it is visible. It has exceptional hexagonal prismatic form, with sharp edges and clean faces that possess the standard vitreous luster. Though one end is obscured by the base rock, the crystal is likely double-terminated. It is colorless, transparent, and moderately clear, as it contains a few tiny solid inclusions and several veil-like inclusions. The dark brown host rock is made of a tough limestone that I am told is a difficult medium for amateur miners to deal with. This host rock has several pits that extend a short way into it- these pits may well have contained crystals at one time which have since been removed.
