Ace of Diamonds Mine & Campground
Middleville, New York
About
Ace of Diamonds Mine & Campground is a family-owned and operated business located in Middleville, New York, that has been in operation for over 50 years. The facility is built around the mining and collection of Herkimer Diamonds, brilliant water-clear quartz crystals found in dolomite limestone formations that are approximately 400 million years old. The campground and mine allowed visitors to experience crystal mining firsthand while exploring the natural geological wonders of Herkimer County, an area historically significant to the Mohawk Indians, known as 'The People of the Crystals.' The business also featured a gift shop offering Herkimer Diamond specimens and jewelry. However, the mine, campground, and gift shop are currently closed due to ongoing litigation involving the property's landowners, with no reopening expected for the 2025 season.
