Majority of them so far look very similar and for someone who is not an expert, it is difficult to recognise what type of gems they are. ### ⭐⭐⭐⭐⭐ Well recieved *by on Reviewed in Canada 16 January 2024* My 10 year old son really enjoyed this advent calendar. I thought it was a nice alternative to candy/chocolate. He looked forward to opening it every morning morning. There is a full list of the Gems inside the flap, and although it appears to line by numbers (25 rocks) there were a couple duplicates and some that did not show up at all. Overall I think the value was there and we enjoyed the learning and aesthetic of the gems as they are now proudly on display. ## Frequently Bought Together - NATIONAL GEOGRAPHIC Gemstone Advent Calendar - 2024 Advent Calendar for Kids with 24 Gemstones to Open Each Day, a Complete Rock Collection Christmas Countdown Calendar with Mini Gemstone Dig Kit - Blue Marble NATIONAL GEOGRAPHIC Magic Advent Calendar 2024 - Kids Advent Calendar with 24 Magic Tricks & Science Experiments, Christmas Countdown Calendar, Christmas Toys, Advent Calendar Magic - Disney Advent Calendar 2024 by ZURU Mini Brands Limited Edition Advent Calendar, 24 Days of Suprises, Mini Figures, Fun Christmas Toys for Kids, Best Gift for Girls and Boys Ages 3+ --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/574887266-national-geographic-gemstone-advent-calendar-advent-calendar-for-kids-24](https://www.desertcart.jp/products/574887266-national-geographic-gemstone-advent-calendar-advent-calendar-for-kids-24) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-15*
