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.\u003c\/p\u003e\u003ch4\u003eTraditional \u0026amp; Metaphysical Associations\u003c\/h4\u003e\u003cp\u003eIn crystal traditions, Herkimer Diamonds are associated with clarity, focused intention, meditation, and the symbolic amplification of personal goals.
