The Ace of Diamonds mine was everything we expected. It was not easy breaking the ruble to find the crystals but it was fun. It took a little bit of time to find the right rocks to break, but once we did we were not disappointed. For our first time mining, I think we did well. We will definitely be... More

If you are willing to go out with a 3 pound hammer and rock chisel this is the place for you. We were there about 2 hours and got 5 stones. 4 good size ones and a small one plus some pieces of rock with small stones in them that we can display. The stones are called Herkimer diamonds and... More

We fell in love with ACE OF DIAMONDS! honestly we were not feeling the Herkimer Mine at the KOA where we stayed. The cabin was great--But we were not feeling it ---UNTIL, the second day when we went to ACE OF DIAMONDS. Totally different atmosphere, and you can FEEL IT. The staff there is wonderful and the owner nicknamed Mr... More

We spent about five or six hours at the mine. We ( hubby and I) brought a small sledge hammer, chisels, claw hammer, eye protection and gloves. At first all we could find were pieces, and the pile of rocks seemed like it was not going to yield anything, but one we got the hang of breaking the rocks, we... More

What a great choice for a weekend road trip. We used a discount website to get a hotel and off we went. We arrived to the mine before the crowds so had our pick of places to stake out. It seems pretty big at first but when the folks start coming in it gets crowded fast. The owners are very... More

We had a great time at the Ace of Diamonds mine. Breaking open the rocks is hard work, the men with me enjoyed it, but it was too much for me (a small woman without much muscle). We stayed at a hotel in Utica. The camp facilities at Ace of Diamonds were very basic. The bathroom was small and clean.... More

We've gone twice (this year and last) and while sifting and picking is fun, the people around you are just as delightful, and generous, as finding diamonds. lol They're diamonds of another sort! It's true I'm not shy and will talk to just about anyone, but the eager and willing responses from prospectors around me only add to the fun.... More

After trying the other Mine , we came here the next day and found it MUCH better. They had a greater range of available types of "Minable" material. From huge rocks to huge piles of siftable dirt/rock. The sifting was a lot more age appropriate for my 7 year old and at this mine we found handfuls of Herkimer Diamonds... More

Having taken cub scouts, my kids, and other people's kids to hunt for Herkimer Diamonds I know that kids do not have to be rockhounds to get caught up in the fun (and hard work) of finding those elusive quartz crystals. I've visited both the mines, which are very close to each other on the west side of Route 28,... More

We went on a family vacation and camped here and mined. We rented hammers and tools of the sort to dig for "diamonds". Fine.. the sites for our family of 16 were all together and nice with water and electricity (we preferred). The guy behind the counter was grumpy. Showers are quarter operated and decent. On day two of the... More
