The Ace of Diamonds Herkimer Mine is located in beautiful Middleville, NY.
The Ace of Diamonds Mine office is open daily and has a wonderful gift shop in addition to mining tool rentals. The fee $8.50 to mine from 9am to 5pm.
There are several ways to find Herkermer Diamonds. There are huge piles of material to look for Herkimer diamonds in. The easiest way is to sift through the dirt and rubble, or you can break rocks open with a hammer and most difficult of all you can try your hand at ledge mining.
Jack is breaking the hard dolomite rock looking for herkimers. You'll notice that Jack is wearing safety glasses and protective work gloves. If you go to the mine be sure to bring gloves & safety glasses if you have them or buy them in the Ace of Diamonds Store.
Steer clear of the commercial mining operation and private claims which are covered by tarps and everything else is pretty much fair game.
Here's a photo of the camping area at the Ace of Diamonds mine. It's not that fancy but a reasonable $15 per night makes it. Do they have hookup's? Yes, for an additional $5 they hook you up with water and regular old 120v electric. BYO wood or it's $5 a bundle.
