​About Us

Herkimer Diamonds are beautiful double-terminated quartz crystals found in Herkimer County, New York. Incredibly, these phenomenal gemstones are close to five hundred million years old. The crystals are magnificent works of nature, found in the rock, having a diamond-like geometrical shape. Thus, the name recognition of “Herkimer Diamonds”.

​The Scialdo family purchased the Herkimer Diamond KOA ​in 1979. ​​​​A family owned and operated business, Dr. Renee' Scialdo-Shevat and Father Rudy ​run the facility today.

Across the street from the Mines is The KOA Resort, situated on the West Canada Creek. The Herkimer Diamond Mines KOA Resort was named Campground of the year in 2010. ​

​​A devastating fire in October 2017 destroyed the historic barn that housed our Registration, Gem Store, Activity Center and Mu​s​​eum.

In 2018, we began a new chapter in our history with the launch of Miners' Village. This improvement will serve the next generation of Miners for years to come!

We invite you to visit and explore this incredible place and prospect for the magical crystals that ​have world-wide acclaim!
