Review: Such a wonderful kit! - I ordered this kit in a rush and was expecting a bag of gemstones. Upon opening the package, nothing was there except a small brick like thing. Kind of disappointing. Things flipped as my daughter and I found out what we need to do. It was so fun digging out the gemstones one by one, cleaning them up, enjoying the beauty of Nature. Best gift ever from my daughter’s comments.
Review: A "gem" of a gem dig kit! - The National Geographic Mega Gemstone Dig Kit is amazing for any kid who loves hands-on activities. My child had a blast digging through the brick to uncover 15 real gemstones, including amethyst, quartz, tiger’s eye, and pyrite. The kit comes with everything needed—a chisel, brush, and magnifying glass—so they can really get into the “mining” experience. The 16-page full-color guide is awesome too, explaining how each gemstone forms and helping kids identify what they find. It’s fun, educational, and kept my little scientist entertained for hours. Highly recommend for a gift or a rainy-day project!

## Questions & Answers

**Q: Do the gems look like the ones on the box?**
A: Dear M. Gibbons:  I sent this wonderful-looking kit to my 6 year-old (wise-beyond-her-years) granddaughter for Christmas.  Here's her reply, which I am copying and pasting, for you:  "Some of them look alike and some are not exactly like they look on the box. There were both rough and some polished."  She typed the reply all by herself.  Hope this helps.  When she visited me in January, her mom and dad took her to our Swap Meet, and she ended up with buying a necklace that had color change stones in it and her sister bought a moonstone necklace that had much of reflective properties in the stones. Both girls' eyes light up now whenever natural-color stones are within their vision.

**Q: Does the kit include aquamarine**
A: No, I don't think it did.  But I'm not sure that they all have the same type in each kit.

**Q: How many digging tools did it come with?**
A: Our Mega Gemstone Digging kit includes one chisel and brush.

**Q: But is it from China?**
A: Yes, our National Geographic birthstone dig kit is currently manufactured in China.

### ⭐⭐⭐⭐⭐ Good gift for 7 gear old
*by A***Y on December 25, 2025*

Kiddo loved this gift! Easy, great fun and enough gems to keep his attention and entertained for about a half hour, then excited to clean off his gems. Keep some water handy to sprinkle on it to soften it for younger kids.
