If you have ever searched for attractive pebbles on the beach then Tumbletopia, World of Stones is the place to visit. It is centred on Tumbletopia Cave - a real Aladdin's Cave. The floor is covered from wall to wall with over 100,000 polished gemstones of over 70 different varieties including amethyst, rose quartz, garnet, tiger eye and jasper. Visitors purchase a collectors bag which they can take into the cave and fill with their favourites to take home - the difficult task is choosing which. Prospect Place is an old Western mine where you can pan for "gold" in the mine stream or gems in the mine carts. There are even beautifully cut emeralds, rubies and sapphires to be found. In the Discovery Zone you can learn how to make fantastic jewellery using stones and beads and can find out about minerals, fossils and Cornwall's geology in the hands-on area.
