About Herkimer Diamonds:
True Herkimer Diamonds are only found in Herkimer County, New York. These amazing quartz crystals formed over 500 million years ago in the Mohawk Valley, perhaps as a result of an ancient sea die-off. Originally known as “Little Falls Diamonds” in the mineralogical community, these crystals grow in pockets within the Little Falls Dolostone that forms our valley. They are double terminated crystals with 18 natural “faces”: 6 on each end and 6 around the “girdle” or middle of the crystal. This gives them the appearance of being faceted. Gem-grade Herkimer Diamonds are the clearest and brightest quartz in the world.
