Save $19: As of December 7, the National Geographic Rock Tumbler Kit is selling for $50.99 at Amazon — this is 27% off its regular price of $69.99 and comes close to the item's lowest-ever price.


We heard you were looking for a flawless gift for the kiddo in your life — whether it be your own child, your nephew/niece, or your inner child (real). Shopping for this age (or age-in-spirit) category can be a tough task, and you definitely don't need even more stress over the holidays. Allow this gift from National Geographic to simplify your life.

As of December 7, you can snag a National Geographic Rock Tumbler Kit for $19 off its list price of $69.99. Now, this isn't the steepest discount we've ever seen on the educational set (that happened when it hit a rock-bottom price of $44.99 back in 2018), but savings are savings no matter how small. And 27% off isn't exactly small.

The National Geographic Rock Tumbler Kit is every tactile learner's fantasy. If you're not up to speed on what "rock tumbling" even is, here's a one-sentence explainer: Turning coarse stones into polished, glam gemstones through some vigorous shaking and polishing. This kit comes with 0.5 pounds of assorted stones from around the world, four stages of polishing rock tumbler grit, an actual rock tumbler with a one-pound barrel, and jewelry fastenings to instantly turn the gemstones into wearables that impress. An easy-to-follow, full-color learning guide will ensure you don't have to supervise the kids every step of the way while they take their first steps into the world of geology.
