Iron is not beautiful but dull is an exaggerated word.
Sedimentary rock can sometimes appear shiny, but this depends on its mineral composition and the presence of specific components like mica or quartz. Some sedimentary rocks, such as shale, can have a slight sheen due to fine particles, while others, like sandstone, may be more matte. Overall, the shiny appearance is not a defining characteristic of sedimentary rocks.
