A craftsman polishes a sculpture of chrysanthemum stone in a processing plant in Majiaping Village of Xuan'en County, central China's Hubei Province, Sept. 6, 2017. With naturally formed chysanthemum-shaped white calcite under the black surface, the chrysanthemum stone is a rare kind of stone resource only found in some parts of China. Sculptors will carve every stone into different pattern or form according to the shape and location of the white calcite, thus all stone sculptures are unique in its own ways. (Xinhua/Song Wen)
