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. Common types of flat stones include slate, shale, and granite, each with unique colors and textures. These stones are often used in landscaping, construction, and art. For example, flat stones can create pathways, patios, or decorative features in gardens. Additionally, they are popular in stone carving and can be used for making slate boards or coasters. Their versatility makes them a favored choice in many projects.
