? Attributes of 925 Sterling Silver Hallmark.If your item contains a S925 hallmark, it is sterling silver. Oxidization. When silver is exposed to air, it oxidizes. The oxidization of the silver causes the metal to tarnish and take on a black tint over time. If you see black tone after a period of use, the item is sterling silver. Magnetic. Like gold and platinum, silver is a non-ferrous metal—it is not magnetic. Run a strong magnet over your item. If the item is not attracted to the magnet, it is made out of a non-ferrous metal.
