of the crystals. Because they are clear, usually colorless, and have facets, much like
traditional diamonds, they earned the name “Herkimer diamond.” The misnomer stuck

Where do Herkimer diamonds come from?
Though similar crystals can be found elsewhere in the world, only those originating in
Herkimer County, New York can be called Herkimer diamonds.
Herkimer diamonds form in cavities inside of dolostone, which is a rock similar to
limestone. The deposits of dolostone in New York are hundreds of millions of years old.
The cavities inside dolostone where Herkimer diamonds grow were believed to be
created by acidic water flowing through the rock. Over time as earth covered the
dolostone and temperatures increased, the quartz crystals formed. (Learn more about

Today, there are a few commercial mines in Herkimer County where you can search for
