Yunnan Red Sandstone are natural sedimentary sandstone sourced from high-quality mining areas in Yunnan, China. Primarily composed of quartz (over 65%), clay (approximately 10%), and goethite (approximately 13%), they are a preferred stone for architectural decoration and artistic carving due to their unique red hue and stable properties. The base color is warm red tones such as brick red, rust red, and scarlet. The texture is uniform and fine-grained, featuring natural landscape patterns, wood grain, or layered textures, with some exhibiting light-colored mineral spots; each piece has a unique texture.
