About Herkimer Diamond

Herkimer Diamond is the traditional trade name for unusually clear, naturally double-terminated quartz crystals associated with the Herkimer County region of New York. Despite the name, these specimens are quartz rather than diamond; they crystallize in the trigonal system, have a vitreous luster, a Mohs hardness of 7, and the chemical formula SiO₂.

Traditional & Metaphysical Associations

In crystal traditions, Herkimer Diamonds are associated with clarity, focused intention, meditation, and the symbolic amplification of personal goals. Their bright, reflective interiors also make them popular as contemplative objects and meaningful display pieces. Metaphysical properties are based on traditional beliefs and are provided for cultural and informational purposes; they are not scientifically established or intended as medical advice.

Why This Specimen?

This crystal offers a distinctly sculptural double-terminated outline, lively internal reflections, and small spectral flashes visible from select angles. Its dark inclusions and irregular contact areas provide natural contrast and character rather than the uniform appearance of a polished stone.
