Budding geologists will love cracking into this giant replica geode! Use the included chisels and hammer to chip away and unearth 12 real polished gemstones, like amethyst and tiger's eye, hiding within. Clean with the included brush and then learn about the history and science of each on the fun-fact poster. For extra fun, there's a second mini geode to dig into!
Ages 4-10 yrs.
