“Another great family experience second year in a row!”

Ace Of Diamonds Mine

Reviewed July 4, 2012

We just came back yesterday and spent 3 beautiful days camping at the KOA. There is no 'deal' or package at the diamond mine across the street from the KOA when you camp at the KOA, so the advertising it all as a 'resort stay' is of no benefit. Having said that, the KOA stay was great, and we recommend sleuthing at the Ace of Diamond Mine. We have experienced both mines, and between the two, we highly recommend the Ace of Diamond Mine which is a few hundred yards down the road. Don't judge a book by its cover - although the Ace of Diamond does not have the visual property frontage to attract sleuthers, it has been the best experience for us between the two mines.
We first went to the Ace of Diamond Mine last summer, 2011, because my daughter saw the show Kirsten Gun Treasure Hunter. We were looking for some good family fun and adventure, and we found it! The people who work here are very helpful. There are a few good reasons to come here: they rent tools to you for only $1 a piece - great deal and a very good selection of tools. My daughter and I liked using the spade and sifter, but my husband and son liked the sledge pick-axe; there are dump trucks constantly moving fresh piles of rock and dirt. We started our hunt through a new pile when it arrived and aside from the ease of loose, soft dirt to sift through, we found at least 6 diamonds within an hour on the pile. We found the staff very accommodating because they told us where we would be lucky, but also...they let us exchange our tools once. That was helpful because if you didn't like the tools you first chose, a change without more $ was nice. On this tool topic, the other mine only provided the use of a heavy sledgehammer, and there were no other options for tools, just the choice to buy a chisel for $14! Overall, we really loved our experience at the Ace of Diamond Mine.

We did try the other mine too, but after finding only about 4 diamonds between 5 of us searching all day, and the mine owner yelling at my daughter for using the water out front to sleuth through her rocks - he dumped her materials and said you can only use the water if you purchase one of their bags for $10 - there were no signs and if he told her calmly without yelling and dumping, she wouldn't have been so upset). We prefer the Ace of Diamond Mine and plan to go again next year! I hope you find this helpful. I am not the type to enjoy providing reviews, but I felt our experience with both mines was important to share for other families to make an informed decision before spending hard earned money. Have fun!

My family has been coming to Herkimer for three years and we decided to take a look at some different mines this time. We are rock-hounds, so if you are a newbie, your mileage may vary. We did find about 3 good size diamonds there, but the staff was not helpful, and it seemed very much like all of the good spots were in someone else's "claim". The "campground" is pathetic, and the mine itself shares a hill with the KOA mine next door.

We went to the KOA mine the next day, and within the first hour we had twice as many useable stones as we had after a day at the Ace. The rock shop was pretty nice though. They have a great selection of hammers and such available to buy.

We sent 2 days with our Mineral club collecting and enjoyed every minute. Be prepared with safety glasses and safety shoes and appropriate apparel for some rock breaking with a large hammer. Large diamonds are only available with some heavy rock moving but many smaller crystals can be found with some effort. While I pounded on larger chunks of rock my wife walked around and found a nice specimen (1 Inch in length) as well as many smaller pieces. (1/4 - 1/2 inch). During the weekend some lucky patrons opened an old pocket to find a number of great crystals. Luck is half the battle!

We had a ball digging for Herkimer Diamonds. Plan ahead to bring a change of clothes and shoes as the dust gets on you quickly. The kids had a ball smashing rocks and finding the quartz crystals. This is not a glamorous experience, and might seem kind of kitschy but it is not every day you get to do this. We brought our magnifying glasses and some bags. The kids just washed their finds tonight and were so happy. Our kids are young so what is better than dirt and diamonds?! The owners were pleasant enough and helpful. I'd say it is what it is, and if you have a junior gem, stone or fossil lover, this might be a perfect adventure. We were there for about an hour and a half but could have stayed longer. We were on our way to Cooperstown and hit this after we had been in Albany. The drive on Rt 28 is pretty farm country.

If you like to dig for diamonds, head on over to the Ace, it's the place!
