Explore the world of a geologist as you dig and reveal precious gemstones with the Discovery Gemstone Dig, Unisex, Teens, Ages 12+! Put on your scientist safety goggles, then dig 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 geologist, use the ceramic streak plate to determine the color of the minerals in powered form. This is the perfect start to an amazing rock collection!
