A stone-filled column and two pencils, booklet, and magnifying glass will spark any child to become a geologist! Easy to carry and beautiful to look at, these tumble-polished specimens range from common minerals to semi-precious gemstones. The rock collection pencils let your budding scientist take their specimens with them.

The booklet encourages children to classify their stones according to hardness and color. Technical language is not used in this introductory kit.

Not for children under four years of age.
