About National Geographic Gemstone Advent Calendar
This is the most-reviewed calendar in this whole category, with nearly 4,000 ratings, and the format explains why: each of the 24 doors hides one real, polished gemstone rather than a toy or a one-time activity, so the appeal holds up daily without needing a new gimmick each door. The final day is a small excavation brick a kid digs into to reveal a rose quartz crystal, a nice capstone after 23 days of straightforward gem reveals.
The included jewelry settings (5 of them) are what turn this from a rock collection into a gift a kid keeps using after December: they can mount favorite stones into wearable pieces instead of just displaying the collector's bag on a shelf.
The Honest Take
What We Like and What We Don't
What we like
- Real gemstones, not costume-jewelry plastic, which holds a rockhound kid's interest
- Jewelry settings extend the toy's life well past the calendar itself
- By far the most-reviewed pick in this category, with a strong rating to match
What holds it back
- Listed for ages 8 and up, small stones need supervision with younger siblings around
- No characters or story, a kid who wants a themed franchise calendar won't get that here
Is This For You?
Who Should (and Shouldn't) Buy This
Get it if…
Get it if your kid collects rocks, likes making their own jewelry, or you want a calendar that builds toward something (a real gem collection) rather than 24 disconnected surprises.
Skip it if…
Skip it if your kid wants a character-based countdown tied to a show or movie they love, this one is about the gems themselves, not a franchise.
