Herkimer diamonds are double-terminated quartz crystals discovered within exposed outcrops of dolomite in and around Herkimer County, New York and the Mohawk River Valley. Not actually diamonds, the "diamond" in their name is due to both their clarity and natural faceting each crystal possess double termination points and 18 total faces (six on each point, six around the center). Because the first discovery sites were in the village of Middleville and in the city of Little Falls, respectively, the crystal is also known as a Middleville diamond or a Little Falls diamond. Herkimer diamonds are prized for their clarity, brilliance and of course their natural beauty is enhanced by the fact that they are ethically sourced in New York State.
