Ace of Diamonds Mine

This place is 300 ft. past the more popular mine in the area and claims to be closer to the actual vein of [Herkimer] diamonds. Very friendly, costs less than the other, and has a nice rock shop. Good for ages 5 and up. The kids stayed interested for hours. Bring safety glasses, large and small hammers, chisels, shovels, sledge hammers. Also bring lunch for the picnic areas. Get there early and plan to spend the whole day. You can rent tools for just a few bucks if you forget your own. Finding the diamonds takes lots of work but it is well worth the effort. Some just lay on the ground as well. Everyone found at least one diamond.
