Channel your inner archaeologist with the Discovery Gemstone Dig! Put on your safety goggles and dive into a hands-on adventure to unearth 11 precious gemstones. As the stones are revealed, carefully chisel around them, brush away the debris and use the included magnifying glass to take a closer look at the patterns and colors within each gorgeous stone. Then, like a real archaeologist, use the ceramic streak plate to determine the color of the minerals in powered form. This is just the start to an amazing rock collection!
