Tumble, polish and discover 8 of your very own gemstones with The Young Scientists Club Gemstone Treasures! This STEM activity kit has everything you need to become a real geologist and see semi-precious stones, like blue apatite, turquoise, amethyst, and tiger eye, up close and personal. Place rough stones and a little bit of water into the rock tumbler, then turn the handle to reveal polished treasures in minutes — it’s never been easier to tumble your own gemstones! Use the double-sided brush & pick tool and polishing cloth to get your premium stones squeaky clean, then grab the magnifying glass, and use the 2-in-1 Geology Game & Poster to identify them and learn what makes each unique! Challenge your friends to a round of bingo and memory using the included game cards and board game, then collect and display your gems for all to see. This science kit helps develop critical thinking skills, identification, curiosity, cause & effect, and so much more. Recommended for ages 6 and up.

  • POLISH & INDENTIFY 8 REAL GEMSTONES: Discover how all-natural, collectible gems go from gritty to gorgeous when you tumble away the rough exterior to reveal a smooth, shiny gemstone!
  • ALL-IN-ONE ROCK TUMBLER KIT: Get professional results in just 60 seconds by pouring the gems and water into the tumbler, cranking the handle and using the included tweezers to remove. This kit has everything you need to experience the real rock tumbling process in half the time!
  • 2-IN-1 GEOLOGY GAME AND POSTER: Use the fully-illustrated identification chart to match, name and compare the gems, then put your knowledge to the test with 40 illustrated gamecards with a round of geology bingo, memory, and even a board game!
  • COLLECT AND DISPLAY: This set includes amethyst, blue, agate, blue apatite, green aventurine, howlite, red agate, tiger eye, turquoise and quartz — perfect for starting a gem collection!
