Toysmith 4M Crystal Mining STEM Science Kit

Become a real crystal hunter. This 4M Crystal Mining Kit hands young geologists a plaster rock with eight genuine crystals hidden inside — and a digging tool to carefully excavate every sparkling treasure, just like a working scientist on a dig.

Chip, brush, and reveal your finds, then study each one and display your collection in the included case. With a drawstring pouch to keep specimens safe, it's a hands-on STEM adventure in earth science that turns curiosity into a real, keepable rock collection.
