The Herkimer Diamond is a type of crystal found in Herkimer County, New York. It is named after the county in which it was first discovered. Herkimer Diamonds are actually a type of quartz, not diamonds. They are double-terminated, meaning that they have two pointed ends.
Herkimer Diamonds are considered to be very powerful crystals, and are said to be helpful for attaining goals and Manifesting desires. They are also said to be helpful for stimulating and opening the third eye chakra.
Herkimer Diamonds are found in a rock called dolostone. The dolostone is broken down over time by water and wind erosion, which exposes the Herkimer Diamonds. They are then collected by people who are lucky enough to find them!
