With the Kosmos Minerals Excavation Kit, children explore the fascinating world of geology. The set contains a soft plaster block in which five real, colourful minerals are hidden: rock crystal, rose quartz, amethyst, aventurine and a red jasper. Equipped with the included hammer and chisel tools, young explorers uncover these natural treasures step by step. A detailed, illustrated manual accompanies the excavation and provides exciting background knowledge about the formation and properties of the stones. Once cleaned, the shiny minerals are ideal for collecting and displaying.
