Kept 5 year old occupied but he was sad because it was missing a stone
This kept my 5 year old son occupied for a good hour. It is very messy but thankfully we did it outside. He had a lot of fun matching the stones to the poster but was pretty disappointed when he couldn’t find the last one. The citrine was missing. Looking at other reviews I guess we are lucky compared to some people who got 0 stones!

Entertainment at its finest
Bought this as a gift for a 6 year old and they absolutely loved it. Perfect for hands on activity and will be entertained for hours!

Tiny stones
My 11 yo daughter really enjoyed this, but the stones that came out of it were small and disappointing. It was quite difficult to chip away at (even with the water) so it’s not one of those ones that crumbles quickly. Most of the rocks were in the perimeter of the block and there wasn’t anything in the center. Lego Minifig for size reference.

Missing a gem
My 6-year-old enjoyed it, but it was much too difficult for my 3-year-old. (I realize what age recommendation it lists). The disappointing thing was that I pounded it to dust for them and it's missing one gem. Very disappointing.

Misleading unfortunately
Fun activity for kids, unfortunately not for gem enthusiasts. The turquoise in our kit was cracked and differently colored inside. None of the others broke, but I can't tell if they're real or not, and that would make someone who really knew their stuff really upset.

Patience is key.
Pretty cool concept, but it was difficult to carve. My nephew is within the recommended age group and he struggled. Although it was long to get to all the gems, he had fu. I had to help him carve out some gems that were really stuck.

Ehhh
Messy and my 4 year old completed it in 15 min. All the rocks were on the top so not very engaging.

Quick but fun
This was easy to use and engaging. Our 9-yr-old finished finding all the gems in 15 minutes. There were two large chunks of rock left over, and she was bummed to be through so quickly. Still fun!

Fun activoty for kids with "indoor rocks"
We really enjoyed this activity! My almost 7 year old bought this with her allowance. She loves collecting rocks and thought this would be really fun. I was worried because some reviews said they didn’t get any gems so I tried to prepare her for that. Most gems were in the center of the brick so once we got there, we found most in rapid succession. Great value, about 1.5 hours total of digging! It wasn’t too messy, we used an old cookie sheet.

Great toy to keep kids busy!
My 5yr old and 3yr old had soooo much fun with this! I made them use it outside though because it was pretty messy. No complaints about the mess though because that’s to be expected with digging lol

Fun & Time Consuming - Missing 1 Gemstone
My 8YO worked on this over the course of 2 days, probably spending about 45 minutes per 'session' for a total of an hour and a half. It's super messy, but wasn't hard to clean up once finished. We were missing 1 gem, which was pretty frustrating. Some of them were small so we thought the final gem was hiding in one of the remaining chunks. However, we pounded everything to dust and still didn't find the last one. This was quite tedious and kind of overshadowed the initial fun for my son. I thought 10/11 is still a good value and it was a fun activity. My son is very literal and likes to complete things, so he felt short-changed. This is why I'm giving it 3 stars. He'd probably rate it a 1, I'd probably rate it a 4 or 5, so taking the average.

No gems!
I gave it one star because 0 was not an option!!!! There were absolutely no gems. We dug for an hour and got nothing! SO DISAPPOINTED. My child was so upset. Just a messy pile of dust. We even rinsed most of the big clumps just to see if we missed something. There were no gems.
