The NOVA Obsidian Excavation Lab lets young scientists chip and chisel away at a mysterious obsidian replica to reveal real gems, rocks, and minerals. Each discovery teaches real gemologist methods—matching, testing, and classifying stones just like the pros.
Once all 13 stones are uncovered, builders apply their new excavation and identification skills to the bonus miniature obsidian dig for even more hands-on exploration. Recommended for ages 4 and up.
What's in the box: Gem-filled Obsidian Dig with 12 gems, bonus mini obsidian dig with bonus gem, 2 chisels, hammer, excavation brush, sponge and guidebook.
