Herkimer Diamond Collection
Herkimer's are widely referred to as diamonds. It is simple to see why Herkimer Diamonds are actually quartz crystals, not diamonds. They are most commonly short and stubby (less than one inch long) and have a hardness of 7.5 on the MOH scale of hardness, with 10 being the hardest (natural diamonds). Rather than a traditional diamond that has a composition of pure carbon (C), Herkimer diamonds, like all quartz crystals, are made of Silicon dioxide (SiO₂).
