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

We went here to find Herkimer diamonds and we did. People were nice in office/gift shop. Camping areas, picnic tables are available and bathroom with showers. 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

The owners were very nice and very kind to our son. They have lots of good tools to rent and very reasonable prices. It... 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

I love that at this mine you have options. This year they added a sluice to the area that has a dirt pile. I found over 50 crystals in the dirt pile. You can either use a sifter or the water sluice. Either way you will find something. You also can break rocks. This is a better mine if you... More

Great time! Owners are very sweet! The people we encountered were all pleasant. It's definitely hard work if you are set on a good haul but worth every bit of it. My boyfriend did great! He is proud of his collection. You will get out what you put into it. Rent/bring sledgehammer! We are definitely coming back in a few... More
