Ace Of Diamonds Mine, Herkimer County, New York, U.S.A.
This small specimen consists of two partially intergrown "Herkimer Diamond" Quartz crystals. Both are in good condition, showing a relatively small amount of damage, and are nearly equal in size. They have the standard chubby, double-terminated, hexagonal prismatic form that is expected of crystals from this locality, and their edges and faces are clean, showing a vitreous luster. Both are colorless and transparent, but show many inclusions, such as air bubbles, included carbon impurities, and internal fractures. I could not locate any two-phase inclusions in this piece, but I did not try very hard, and are many bubbles to examine.
