The material on this website presents the history of Herkimer diamonds, pictures of all the minerals, and information about every mine - deposit in the Herkimer diamond mining district. It is an ongoing COMMUNITY research project (meaning that people contribute to the project) focusing specifically on deposits of quartz crystals in and around Herkimer county, New York, USA. The Herkimer diamond deposit (a Herkimer diamond mine if it is a commerical venture) MUST contain double terminated quartz crystals showing the characteristic form of "Herkimer Diamonds".
Since 1999 there has been considerable new research related to Herkimer diamond mines - deposits. This website combines this recent information with new field, and laboratory, evidence from each of the Herkimer diamond mines - deposits. There are over 40 individual webpages of information about Herkimer diamonds, presented in a format that is easy to understand.  The goal to be the most informative FREE website about Herkimer diamonds, meaning, definition, tips, what, how and why, along with descriptions of different mines in the region. This site will be updated regularly - usually over the summer. This is a HUGE project it needs YOUR help!
