Pure silver must generally be polished and cleaned on a regular basis to keep it from becoming tarnished. It should not be placed in areas where it will be exposed to large amounts of oxygen and should be taken care of in special silver storage containers. Oxidized silver will not be affected by the tarnish and the tarnish will allow the silver to take on a more oxidized work. Oxidized silver does not have to be polished or cleaned and can generally be left in any type of environment.
Pure silver is found only in the ground and is not combined with other elements to make pieces of jewelry or home decor items. It is the most reactive silver and will tarnish more quickly.

Sterling silver is much harder than pure silver and is able to stand up to daily use.Learn more about States of Matter
