This post will guide you through what makes Herkimer diamonds special, how to visit the mines, and tips for finding your own crystal.

What Are Herkimer Diamonds?
Herkimer diamonds are not actually diamonds. They are double-terminated quartz crystals that form naturally in dolomite rock. Their name comes from Herkimer County, New York, where they were first discovered in the 18th century. These crystals stand out because of their exceptional clarity, natural faceting, and sparkling appearance that resembles real diamonds.
Unique Features of Herkimer Diamonds
Double Termination: Unlike most quartz crystals that grow attached to a base, Herkimer diamonds have points at both ends.
Exceptional Clarity: Many are clear enough to see through, sometimes with interesting inclusions like air bubbles or rainbow-like reflections.
Natural Facets: They form with 18 natural facets, giving them a diamond-like sparkle.
Size Variety: Crystals range from tiny points to large specimens several inches long.
These features make Herkimer diamonds popular among collectors, jewelers, and metaphysical enthusiasts.
