A geological expedition in the palm of your hand! This gift set, perfect for geologists-in-training, is filled with 24 individually wrapped mini excavation blocks. 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 (there's a tool for each block in the set) to dig in and reveal one of 12 different minerals or fossils: amethyst, aventurine, quartz, rose quartz, red jasper, pyrite, pisolite, snowflake obsidian, ammonoidea, scleractinia, petrified wood, or crinoids. Ideal for geology enthusiasts, These mini excavation kits are great for starting a new rock collection (or adding to an existing one!). instructions are also included.
