National Geographic Advent Calendar


Kids love rocks, gems, and fossils, and this exciting Christmas countdown calendar will give them a new specimen to add to their collection each day as the holiday approaches. Each day leading up to Christmas, kids open a panel to reveal a special rock, mineral, fossil or gemstone! With this Christmas countdown calendar, they can start a rock collection they will enjoy all year round, with storage bag included!

The final piece in this collection is a stunning Rose Quartz specimen that kids will unearth from a mini dig brick. Dig tool and brush included, with a magnifying glass for looking at all the pieces up close!
