Yunan White Sandstone is a type of light sandstone that features a white or off-white background color with subtle patterns and textures that resemble sand dunes. The texture of Yunan White Sandstone is usually honed or bush-hammered, with a slightly rough surface that has a matte finish. It is known for its natural and organic appearance, making it a popular choice for interior and exterior design projects.

Yunan White Sandstone is commonly used for flooring, wall cladding, countertops, and decorative elements such as garden features and sculptures. Its soft and gentle appearance can add a sense of calmness and tranquility to any space. Yunan White Sandstone is also known for its durability and resistance to weathering and erosion, making it a practical and functional choice for outdoor applications. However, like all types of natural stone, it may require periodic sealing and maintenance to preserve its appearance.
