Like Curling Stones are a type of stone used in the sport of curling. They are made of GRANITE, which is a type of igneous rock formed from cooled magma or lava. The stones are typically round and flat-bottomed, and are designed to slide across the ice while maintaining a consistent speed and direction. They are also designed to curl, or turn, when they come into contact with the ice. The weight of the stones varies depending on the type of curling being played.
