If you're a rockbound this is a neat gift

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!

I bought this for my 4 year old gdaughter and she asolutely loved it. We talked every day and she shpwed me her new "jewel" or rock. All of the adults were very impressed with this gift. I worked at a Montessori School for 15 years and i am so thrilled with this item - I am gifting one to each of the 3 classroms this next year - and all her cousins!

Gift for 4 yr old granddaughter. What 4 yr old doesn't love pretty rocks!!! As of Dec 2, the two days that she has opened are beautiful. I am a bit disappointed in the calendar construction. I assumed it would have little windows that would be storage compartments for the rocks. No!! Only cardboard pull offs that do not attach back. It comes with a pretty fabric drawstring bag for rock storage. However, she is thrilled with it, so Grammy is happy.

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.

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