Herkimer Diamonds are a unique and rare form of quartz that are only found near the Mohawk River in Herkimer county, New York. These gemstones started forming 500 million years ago and are the only quartz in the world to naturally form double terminated shapes, meaning that all other quartz only has one natural pointed end whereas Herkimer Diamonds have 2 pointed ends naturally. In other words, they are not cut to have this special shape, they come out of the ground that way shaped by Mother Nature herself.
