4 star review

A wonderful place for kids to experience rocks and gemstones. We spent about an hour here. The “gemstone paining” is a MUST DO for kids and a great value starting at $7.00 a bag. Did take off one star for not having restrooms available.

LOTS of rocks and fossils. All different sizes and qualities. Love this big, pink quartz. I'm sure you could buy it if you could carry it. (But you can't have the old guy leaning on it)

We loved this place! Spent an hour and a half just looking at all of the amazing rocks and gems, then our kids went back again a few days later. This place is literally a museum with the owner's extensive collection on display, which has some amazing stuff. Great prices too and an amazing variety! My adult kids did the gem mining outside, which was fun and worth the price. You can buy a dollar rock, big Solo cup loaded with local rocks for $5, split a large geode for $15, buy huge rocks by the pound, or get amazing imports from around the world! The workers answered lots of questions for us and were very knowledgeable. You must visit!

This place is so worth stopping in for, there is so much to look at from fossils, arrowheads, rocks and all kinds of tourism buys. The prices I believe are pretty reasonable and the owner is super nice. The facility is clean, organized and lots of labeling. Parking is easy and lots of it. Nice job!

We spent a day in Custer after traveling from Oregon on our way to Iowa, and Ken’s Minerals ended up being one of the best highlights of our trip! My kids and I still talk about all the incredible specimens we discovered here — each one more unique than the last. The prices were amazing, and the gentleman who helped us was polite and informative. Don't give into some of the tourist trap stores... save your money for something unique and lasting. I highly recommend stopping here if you’re anywhere near Custer!
