Dig It Up! Minerals and Fossils
A different surprise lies inside each of these clay stones, just waiting to be discovered. Simply chisel away the stone to excavate petrified wood, fool's gold, amethyst, snowflake obsidian, and 8 other minerals and fossils.
Set includes one dozen individually wrapped clay stones, each with a chiseling tool and instructions—it's a perfect activity for groups or parties! Identify and learn about your geologic discoveries with the accompanying Field Guide to Fossils and Minerals.
Age Recommendation: Ages 4 and up
My 5 year old and 4 year old both love this so much! They also shared with a few friends who loved doing it. They still play with the gems and my daughter asked for a new kit for her birthday. Lots of fun!
