Herkimer Diamond originates from the Herkimer Mine in New York. The crystals are short, double terminated, and of dazzling clarity, so superficially resemble a diamond. There have been a few similar deposits discovered recently, notably in Tibet, although without the same level of clarity and light refraction. The hardness is 7.5, slightly higher than other quartz, apparently because it is formed deeper in the earth’s crust, and therefore under higher pressure.
Properties: Use Herkimer diamond primarily with the Crown and Upper Crown Chakras, for clearing and bringing in Divine light, as an attunement stone, and in meditation and dream work.
