Ace of Diamonds Mine

Located adjacent to Herkimer Diamond Mines along Route 28, Ace of Diamond Mines is a tourist stop between Middleville and Herkimer in New York.

The mine is more of a gravel pit. Prospectors mine Herkimer diamonds here, which are faceted quartz crystals that are pointed on each end. This is one of the few places in the world where Herkimer diamonds can be found. They are popular gems among those who study metaphysical energy. Some claim that the "diamonds" can aid sleep, hasten healing, and enhance meditation.

The mines are visited by both tourists and vendors who sell the diamonds, but both groups will find what they are looking for and are accommodated by the mine. In the gift shop, visitors can purchase food or souvenirs. There are also some Herkimer diamonds on display and for sale in the Rock Shop. The mine opens daily from 9:00 a.m. to 5:00 p.m. from April 1 through October 31.

Ace of Diamond Mines is located near a KOA Kampground about one mile south of Middleville, NY. The mines are popular in the spring and summer season and are available to group tours. Families and children are welcome and special rates for the kids are available.
