Herkimer Diamond is a type of quartz crystal, which originates from Herkimer, New York. It is always double terminated and of dazzling clarity, often full of rainbows. It is believed to have formed more deeply in the earth’s crust than most quartz, and has a hardness of 7.5, as opposed to quartz’s 7, probably giving it a higher light refraction. Similar crystals are mined in a few other places, most notably China, and are often marketed as Herkimer diamonds.
Properties: Herkimer diamond has similar properties to clear quartz. In addition, it stimulates psychic gifts, and because of the pure light it brings in, it is used to clear the Chakras. It is considered an “attunement” stone as it is a powerful aid in attuning to another person, one’s environment, or the highest spiritual levels, as well as helping us to gain past-life information. It is also a good aid in treating and eliminating electromagnetic stress.
