Not as cool as it could have been

I received this as a gift for completing my graduate gemologist diploma; it was a really thoughtful gift and it looked pretty cool in pictures. I could accurately identify all the gems, so kudos for that. It's hard to explain but there's just something off about it. The fluorite looks like a fish and I cannot un-see a fish when I look at it. The Watermelon tourmaline looks like a pill container and is by far the worst looking one, the pyrite is way too lackluster (literally). If they couldn't accomplish the almost mirror shine of it then pick something else. The amethyst and rhodochrosite are the best ones. Having two quartz-based minerals is sort of lazy, they would have been better off keeping the emerald from the prototype. I don't have an issue with the look of the stands, but they are very repetitive to build. Overall, this is a really fun set for someone like me say they to have, but I feel like it could have been better executed.
No, I would not recommend this to a friend.

We appreciate you taking the time to share your thoughts with us! We’re really happy you enjoyed receiving the Mineral Collection.

I would say this was my favorite build ever. Besides loving the subject matter, it was satisfying and I marveled at how it came together --especially the amethyst geode. Truly beautiful. I also love that it can be displayed in many different ways and placed together or separately. I wish my dad were still alive to have joined me in the build. He would have loved this since we were rock hounds and collectors when I was growing up.
I would recommend this to a friend!

If you're a dedicated lego maniac and have a love for geology, this is the set for you. It was a blast to build from the first brick and looks great next to my work setup.

This was a very nice set and I got it to do a comparison with the real minerals for a project.

Easy to put together. A 10 year old mastered this in a few hours. Looks great.

Fun build!

This was a really fun build. I used the Lego app instead of the instruction booklet. There were a few places the instructions didn’t match exactly to the booklet, but it was easy to figure out what needed to be done. Looks nice displayed on my shelf. Like that I can change position of the minerals.
I would recommend this to a friend!

Unique and fun

[This review was collected as part of a promotion.] This Lego set is awesome. It’s such a unique set and was easy for my 10 year old son to put together. Not only does he love Legos but he loves gemstones and minerals so this was perfect for him to do. Many of the pieces are small so he had to put it together away from my toddler. What a great piece to add to his collection.

Love it but my poor old eyes...

I am glad to see that I am not the only one who had a hard time distinguishing between colors in the instructions. It was incredibly frustrating. This is the only drawback of this set in my opinion. I hope to see additional "specimens" although I am guessing that this set is not a best seller deserving of a sequel.
I would recommend this to a friend!
