The group of minerals that can exhibit both dull and shiny appearances is known as "ores." Ores contain valuable minerals and metals, and their luster can vary based on their specific composition and surface characteristics. Common examples include sulfide ores, which may appear metallic and shiny, and certain oxides that can be more dull or earthy in appearance. The visual properties often depend on factors such as crystal structure and weathering processes.
