Hidden among Upstate New York's dolostone formation is a stunning group of crystals called Herkimer diamonds. With their striking clarity and beautiful double-terminated growths, Herkimer diamonds have been catching the eyes of humans since at least the sixteenth century.

This specimen is a Herkimer diamond druzy formation, measuring 3.65". It was mined in the famous Little Falls Formation, which remains the most prized site for the crystals on Earth.
