These distinctive gemstones are a type of quartz crystal, notable for their exceptional clarity and natural facets. Typically double-terminated, meaning they have points at both ends, they often appear as if they have been cut, though they form this way naturally within the rock. Their name reflects their origin, being primarily found in and around Herkimer County, New York.
Their appeal stems from their brilliance and unique formation. Often used in jewelry and metaphysical practices, they are valued for their purported energetic properties. Historically, they have been collected and admired for their visual characteristics, standing out amongst other quartz varieties due to their shape and internal structure. Their discovery contributed to the region’s geological significance.
