Answer:

LUSTRE

metals are lustrous or shiny (see in pictures ).It means that metals have a shiny appearance. If you carefully observe the freshly cut surface of metals, you will find a shiny appearance. It refers to metallic lustre. The shiny appearance of metals, such as gold, make them useful in making jewellery and decoration pieces.

however, non-metals are non-lustrous or dull except iodine and graphite which are lustrous.
