NATIONAL GEOGRAPHIC Rock Collection Advent Calendar 2025 - Advent Calendar for Kids with 24 Gemstones, Minerals & Fossils for Kids, Complete Gem & Fossil Collection Christmas Countdown Calendar

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!

Bought this for my rock crazy kid. Since it's Dec. 9th I let her open the first 9 to catch up and she absolutely loves it. You get nice and good sized pieces. 100% worth the money. This advent calendar is fun, has good instructions, has a nice Veriety and the packaging is also quality.

This was a gift for my best friend’s son for Christmas, and he just absolutely flipped out. It made me feel really good to see him so excited.

Besides a missing rock my grandson loved opening this every day. So much better than candy!

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 had ordered a National Geographic Advent calendar. It's a really neat calendar with various rocks for each day. The tool kit was missing. I sent them an email and they responded immediately, telling me the tool kit was on its way. Will definitely buy from them again:)

Bought this for my dad and he loved it!

My son has recently been interested in rocks, so I thought this would be a fun advent calendar for him. While we have enjoyed it, we have been a little disappointed in the specimens; many do not look like the pictures inside the box which has made identification harder than it should be if the samples aren’t labeled. I am not seeing the value as some of the samples are small and dull, compared to what was advertised.
