The crystals are magnificent works of nature, found in the rock, having a diamond-like geometrical shape. Thus, the name recognition of “Herkimer Diamonds”. Herkimers rival true diamonds. A true diamond found in the rough is exactly that, a rough appearing glass-like stone. The true diamond must be painstakingly cut by man to give it smooth faces and a geometrical shape. On a hardness scale, a true diamond scores a ten. Herkimer Diamonds falls at a 7.5 on the scale, giving the real diamond a close race. They are naturally faceted, each having eighteen facets and 2 points.
