National Geographic Gemstone Advent Calendar $29.99
Final Cost ONLY $20.49!

This advent calendar includes 24 different gemstones from around the world including agate, green aventurine, hematite, sodalite, turquenite, tiger’s eye, blue calcite and more! And final piece is a rose quartz that kids unearth from a mini dig brick (just like a real geologist!).

Plus, it includes five jewelry settings so kids can create their own jewelry with their new gemstones!

This advent calendar is much better than expected! We’ve only opened 16 days of surprises and every piece is beautiful. We also appreciate that most crystal are polished with nice smooth surfaces. There are also pictures and information about the crystals on the other side of the box. It’s so much fun to match each crystal to the picture and read about it. We can’t wait to see what crystals we’re going to find next!
