We stopped by Ace of Diamonds to check the place out to bring our grandkids once school is over. Then we checked the competitors down the road and we decided that Ace of Diamonds would be much better for kids since it has a huge sluth for the kids to mine in. The place is kinda run down and old.... More

We went last summer, so it was pretty hot. We brought a hammer and set of chisels with us, but they were nowhere strong enough to break the rocks. We rented a sledge hammer and a bigger chisel (reasonably priced in the store). I could have stayed all day, but the kids (11 and 12) were bored almost instantly, and... More

We have been visiting the Ace for many years. We are always pleased when we are out in the fresh air finding crystals. They have an extensive area to explore and search for Herkimer Diamonds. The atmosphere is low key and rustic. Fun times in the foot hills of the Adirondack Mountains.

I truly witnessed the generosity of New Yorkers this past week at the mine. It was my first time at ace of diamonds, and an angel of a woman showed up early afternoon, and showed us all the best places to look for crystals. She was a local and went there all the time, so when she found a large... More

We got here around 10:30am and continued til almost closing time. There are plenty of places to smash rocks and people with extra time can actually mine solid walls of limestone. There were a few kids here when we went and most of them seemed to be having lots of fun looking for diamonds. The rocks are somewhat difficult to... More

My husband and I dug, cracked and moved piles and came away with 2 5 gallon buckets of diamonds in matrix and at least 23 perfect and semi perfect loose diamonds! This trip was our best. On day two, we scavenged new piles behind the Office and actually found a perfect 1.5 inch diamond specimen and several small perfect ones.... More

This is suppose to be the best place to go hunting for your diamonds! We did come home with a five gallon bucket of rocks with diamonds in them plus lots of loose ones.... More

I stayed here for two nights with my girlfriend and her family and came away not all that impressed. The digging is incredibly fun, and actually more enjoyable than the other mining site down the street. So if you are stopping here for the mining alone then I do recommend this place. However, if you decide to camp here, there... More
