Don’t miss the 2nd Herkimer Diamond Mining 101 w/PatRocks at Crystal Grove for 2023! Come on out and get some FREE mining instruction from someone who knows Crystal Grove well, along with the Herkimer Diamond district! He’ll be on-site to answer basic questions, teach you mining tips and tricks and getting you prepared to mine for these beauties on your own!
This has always been a good time and our miners leave with much more knowledge on the geologic formations of the district, the many strategies for mining Herkimer Diamonds, tools of the trade, the history of the Herkimer Diamond and so much more!
This will be available all day, both June 17th & 18th, no reservation needed.
