Flat stones are naturally occurring rocks that have a smooth, even surface and a relatively thin profile. They can be found in various environments, such as riverbeds, beaches, and mountains. These stones are often used in landscaping, construction, and art due to their aesthetic appeal and durability. Common types of flat stones include slate, flagstone, and shale. They can be shaped and cut for specific purposes, such as paving pathways or creating decorative features in gardens. Their versatility makes them popular in both functional and decorative applications.
