Fun fact: Oxidized silver is darker than other types of silver, with little to no luster. Oxidized silver is created through a process of controlled oxidation, where the silver is exposed to the environmental factors that cause tarnish. Oxidized silver requires less maintenance than sterling, and further tarnish simply makes the silver more beautiful.
