Herkimer, New York is a sleepy little town along the Mohawk River, with just under 8,000 residents. It boasts an abundance of natural beauty that has attracted city slickers from Manhattan for years. of course, beauty is pretty easy to come by in upstate New York, but what really put Herkimer, NY on the map was the discovery of hidden gems in the dolostone outcroppings throughout the county.

In the late 18th century, as workmen were busy cutting into the dolostone along the Mohawk Valley, they discovered large amounts of incredibly clear quartz crystals within the rocks. The quartz is double terminated, which means it has two naturally faceted ends, making them much rarer than common quartz.

As the popularity of the gemstone grew, they became known far and wide as Herkimer diamonds, and the town of Herkimer, NY was forever changed.

Today, you can visit several privately run “Herkimer diamond mines” to hunt for your own special gems. Not only is the Herkimer diamond incredibly beautiful, it is also said to have mystical powers, and well, who can resist a bit of geology and magic? Certainly not us!

The Ace of Diamonds: Herkimer Diamond Mine and Campground

Sound just a little too kitschy to be real? It is — and we loved every minute of our stay at this rural campground and Herkimer diamond mine! We settled into our quiet little campsite just after noon so we could get right to work. We wanted to have plenty of time to hunt for those precious Herkimer diamonds. 

When we pulled into the Ace of Diamonds mine, we were greeted by a huge pile of rubble. This is dolostone that has been broken up and moved around with excavators. For $10 ($5 for kids under 7), you can pick around in the rubble in search of Herkimer diamonds, or you can bring your hammers to chisel away at the rock cliffs surrounding the mine. I expected that I would just set up camp and watch the kids hunt for diamonds, but it was totally addictive, and before long I was mining like a true prospector.

 During our visit, we discovered lots of small Herkimer diamonds, but we kept on searching for the elusive big prize (we never found it). Before the Ace of Diamonds closed for the night, we checked out the on-site rock shop and we were totally blown away. It was one of the  most interesting and wonderful souvenir shops we have ever seen. Some examples of their wares: a giant tiger kite hanging from the ceiling with a papier-mache body and about an eight-foot wing span (all handmade), and books ranging from woodsman/woman skills, legends and ghost stories of the valley, encyclopedias on infamous plants and herbs, subjects of divination and lots more. Of course there was a dazzling array of stones and gems, a few from Herkimer, but many from all over the world. We were totally smitten with the place.

You can rent these hammers at the campground or bring your own.

After dark, when the rock shop and mines are closed, and the owners go home, the campers are basically left to their own devices. We watched a glorious sunset, walked the hills, and hung out with some of the other campers. It’s such a small, mom-and-pop operation, but perfect for families and rock hounds.
