Turn ordinary stones into dazzling gems with this Rock Tumbler Kit! Kids can explore geology, mineralogy, and the science of abrasion while polishing rough rocks into smooth, sparkling gemstones. Perfect for hands-on STEAM learning, this kit teaches how gemstones are formed and how rocks can be transformed through grinding, polishing, and patience.
The kit includes 9 rough gemstones, a full pouch of extra rough stones, and polishing grits. A noise-reduction cover makes tumbling quieter, so the whole family can enjoy this educational hobby. Once polished, stones can be turned into jewellery or keepsakes for a tangible reminder of your scientific exploration.
Includes: stone grinder, rotating bucket, acoustic enclosure and base, 9 raw stones, 50 g of 150-mesh powder, 50 g of 600-mesh powder, 100 g white crystal, 50 ml measuring cup, jewellery accessories kit, 2 velvet bags, USB wire, and illustrated instructions.
