A geological expedition in the palm of your hand! Each block contains one real mineral or fossil specimen. The kits are blind-packed, so it's a surprise which of the specimens you will get each time! Use the included chisel tool to dig in and reveal one of 12 different minerals or fossils: amethyst, aventurine, quartz, rose quartz, red jasper, pyrite, diorite, pisolite, honeycomb coral, sea lily, petrified wood, or crinoid. Ideal for geology enthusiasts, these mini excavation kits are great for starting a new rock collection (or adding to an existing one!). Every gift box includes its own chisel tool as well as a full-color instruction manual. Each rock sold seperately.
