Customer Reviews for LEGO - Ideas Mineral Collection Building Set for Adults - 21362

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.

Beautiful display piece
on December 14, 2025

[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.

I was excited for this set - it had such great potential. The end result was underwhelming, and surprise, surprise - pieces were missing... again. This is the 4th set in a year that has been missing pieces. If I could sent this back for a refund, I would. 3 out of the 6 minerals are nice, the remaining ones - look more like lumps of plastic that do not offer anything to the imagination. The stands are a cool idea, but poorly implemented and flimsy. Considering the price of this set - I cannot bring myself to take it apart and add the pieces to the spare Lego parts. Save your money for a better set or wait for this to go on sale.
No, I would not recommend this to a friend.

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.

The perfect Lego set for my daughter
on December 4, 2025
Posted by: avirya_4691
[This review was collected as part of a promotion.] My 9yo daughter and I are avid rock and gem collectors, plus she loves Legos, so this was the literal perfect set for her! This was actually the first Lego that she’s completed all the way through with minimal help, which man’s it a huge success. It was easy for her to do with just a bit of assistance and it looks beautiful sitting in display! It did come with a couple of pieces missing, but she was able to use another piece from her stash.
