The Herkimer diamond is double pointed Quartz Crystal that has already been faceted by nature.
Herkimer Diamond is double terminated crystal (there is a point at each end of the crystal). It is water clear and different from Quartz. It is a very powerful balancer of the body and emotions and should be used carefully. Double terminated equals super power.
The Herkimer comes from only one place - Herkimer, New York, in the United States. The bedrock in which the crystals are found began forming approximately half a billion years ago in a shallow Cambrian Sea that lapped against the southern shores of the ancestral Adirondack Mountains (near the town of Herkimer, New York).
