Thanks and Recognition

Collecting Tips and Resources

There are many people who have gained knowledge about Herkimer Diamonds, how they are found, and how the occur in the rock. Here we will acknowlege those people who share any knowledge, photos or specimens that contribute to this website. This website is a community project and it grows because of the contributions people make to the website.

Special recognition to the staff of the New York State Museum for their support and encouragement
Thanks to Amy Wilkinson for her support with microscope pictures.  All microscope pictures are done with the support from the NY State Museum.
Thanks to Mike Eggleston for his help and support. Mike is one of the few folks thus far who has contributed "junk" specimens to the project.  They were very important in advancing our knowledge.

If you are looking to buy Herkimer diamond specimens go to his site.  If you don't see what you want send him an email.

The owners of Turtle Clan Ridge (private location) have donated specimens to be photographed, donated "junk" material,  and allowed unparalled access to the location to help advance our understanding of Herkimer diamonds.  A big leap forward in understanding the history of Herkimer diamonds is due to their efforts. A huge hand of gratitude to them!

Thanks to Bill and Anne for their enthusiastic participation in this community project and their promise of contributing "junk specimens" whenever they can.  They are the Canada connection for Herkimer diamonds.  Visit them at
Ted Smith, the owner of "Ace of Diamonds" in Middleville, NY was gracious and helpful.  He not only took time to provide total mine access, but he also donated specimens for research.
Thanks to Bob from N. Adams who sent a box of very useful specimens.  He has also promised to be a continued supporter of this research which is shown throughout this website in the careful eye he has for odd features.
There are other folks who have contributed photos. Their names are given throughout the website.

Although there are links below that provide some "tips" to help you collect Herkimer diamonds, one of the best tips is to increase your knowledge on how they were formed. Visit all the pages on this website and expand your knowledge. In the future we will have "tips" for every mine, because each mine is slightly different. You can access individual mine information by clicking on Directions at the top of this page.

On this web page is general information, and tips, to help with collecting Herkimer diamonds.  It is information that, in most cases, can be applied to every mine/deposit in the Herkimer district.

Important Note:   Herkimer diamonds occur in zones, or layers.  For a discussion of this click on the following link:
Note the strong development of the blocky features in the host rock.  Blocky rock is chracteristic of the entire Herkimer district. Knowing how to move square blocks really helps with collecting.

More collecting tips will be added in the future.

Thanks to Frank from Little Falls, NY who donated specimens (the photos of which can be seen throughout the website), provided access to his collection, and donated photos.  His support to this website has been exemplarly and it has advanced the history of Herkimer diamonds.
