Nice rocks
I didn't know what kind of advent calendar to get my grandson, 11. We've had candy, legos, puzzles, gnomes, little animals, and moochis, over the years. This year I was stumped so I selected this because I always like National Geographic magazines so I felt confident this would be nice. He loved it. He looked forward to a new rock every day. Learning about the rock, collecting in daddy's office. It was a hit.

Unique
My youngest son loves rocks and this. Each day a surprise. I wasn't expecting the items to be as big. It has been a great learning experience for my son and each day he learns something new about the item. It offers a range of bright colors and each is shown uniquely. However, the day day left something to be desired. I expected something hidden where you would have to break open to see what eas inside, like the pictures showed. Instead it was a unique piece of chalk. The chalk looked cool, but that was about it.

Fun For Adults, Too!
I posted about this calendar on social media when I first heard about it, and one of my followers gifted it to me! I have had so much fun waking up each morning and opening a new little door. I'm only halfway through the month, and I already have plans to get one of the other national geographic Advent calendars next year, I'm having so much fun with this. So far, it has been a really interesting mix of polished stones, crystals, a geode fragment, and lots of fossils like an urchin and a bivalve. The kit comes with a little magnifying glass and dig tool, and also a little bag to store your treasures in. A handy chart on the side gives you a little guide so you can figure out what the days find is and learn a few interesting facts about it. I have told so many people about this. Can't wait for my big dig kit I get to open on day 24!

Fun alternative to candy Advent calendars
If your house is like my house and you end up with a surplus of candy that extends from Halloween all the way to Easter then you probably welcome a non-candy filled Advent calendar. This calendar from Nat Geo is lots of fun for little kids who have rock collections or gravitate to the rock display at the National Park gift shops. It has many of the same rocks they sell at the displays. These rocks are reasonably well polished, none are rough cut. There's a bag to put them in as you go through the days. Some rocks are hard to discern from the others (we aren't geologists). I keep telling the kids that we'll go back at the end and line them all up with their spots. Don't remove the date covers. The picture in the background is the Northern Lights. The kids like being able to see it when they replace the covers.

Missing days…
Missing rocks/minerals/fossil for at least 2 days so far. As you can imagine, it’s been disappointing.

Para un adulto. Pero para niños también está padre. Vienen todas las piedras que marca la caja. Vale la pena.

J’ai acheté ce calendrier pour mon petit fils de 10 ans qui parle français. La description des pierres est en anglais seulement, ce qui n’est pas mentionné sur le site lors de l’achat. Grande déception…….. pour le prix payé. De plus la boîte est arrivé non emballé et donc aucun nom de l’acheteur…"la. Personne qui l’a reçu se demandait à qui appartenait ce colis. Très très déçu. Je ne recommande pas ce produit….
