Fun tandem build or lap tray build
on December 7, 2025
Posted by: CJmoose
Verified Purchase:No
This set was a gift from my husband. I’m a geologist, and the only thing I love more than him and our cats are Legos and rocks. So this was perfect for me.
I specifically wanted to mention that this is a great set 2 or 3 people to build together. You can divvy up the minerals and booklets so that each person has their own build.
This would also be a great set for someone who is sick or hospitalized. Each mineral stand and each individual mineral has its own bag. So you can do this build one mineral at a time on a lap tray or over-bed table while confined to a bed or recliner. Some sets need a larger assembly space, so I like to point out when I find one that can be used by people with limited workspace.
My one caveat is that this set is a bit fragile. Once you’re done, make sure you put it somewhere where a young child or cat can’t fiddle with it.
I would recommend this to a friend!

There are better sets
on December 23, 2025

[This review was collected as part of a promotion.] There were some missing pieces, making this difficult to put together. We had to go back and restart using extra pieces in place of the missing ones. It looks cool when done and makes the minerals look like they have different shapes and textured crystals.

This is by far the WORST booklet I've ever had to use. The colors of the parts are SO confusing. It's hard to tell blue from green, blue from purple. We guessed at a lot of parts and used extras that we have to complete it. That's my only complaint
No, I would not recommend this to a friend.

Cool set
on November 21, 2025
Posted by: jennajburn_2625
[This review was collected as part of a promotion.] I would call myself a LEGO novice (this is my 3rd set) but the overall build was easy. The instructions were clear to follow, and I completed the set in 2 hours, and there were no missing pieces.
As a gemologist, I was excited about the idea of having the rough gemstone Legos to display in my office. While they don’t really look like the real thing, they still make a cool decoration. The overall set is slightly smaller than I was expecting but still looks nice.

I was really excited when I first saw this set, especially since I’m a huge fan of minerals and stones. Unfortunately, after putting it together, I was left feeling pretty let down. The finished build doesn’t resemble the stones or minerals in any recognizable way—it just misses the mark entirely.
I was hoping for something that would really reflect the unique and mesmerizing beauty of minerals, but unfortunately, this set didn’t hit the mark.
No, I would not recommend this to a friend.

Beautiful display piece
on December 14, 2025
Posted by: jenniferh276f_176
[This review was collected as part of a promotion.] This is a great set! My 8 year old loves Lego and also collects gemstones so it was perfect for him to build. It’s a beautiful display piece. The biggest complaint was that one of the instruction booklets was misprinted and was missing some pages while other pages were out of order. But we just used the instructions online and everything came together.
