Quartz Crystals from the Herkimer County, New York locality are known as Herkimer Diamonds due to their exceptional clarity, often double terminated structural formations, and various inclusions of solid, liquid, and gases such as Anthraxolite of black carbon, Ehydro of ancient water, and Petroleum. Diamond Quartz Crystals with similar characteristics as the Herkimer Diamonds do occurred in other localities around the world, but Herkimer Diamonds are only found from around Herkimer County, New York.
Metaphysically and energetically, Herkimer Diamond Quartz Crystals in general are high vibration Crystals. Personally, they are wonderful with meditation for in depth personal introspection, finding the Light to guiding your path on your spiritual journey, and great with amplifying the energies of other Crystals.
