Understanding Why Sterling Silver Jewelry Tarnishes. The tarnish on sterling silver jewelry is the result of oxidative reactions with sulfur, such as Hydrogen Sulfide, in the air and environment (the nickel or copper alloy in most sterling silver also undergoes its own oxidative reactions). The corrosion of silver combined with sulfur creates the darkening referred to as tarnish. Therefore, you must insure your Tiffany & Co jewelry is clean and dry before storage; since any moisture, dirt, oils or other residual chemicals will accelerate the tarnishing.
A container that locks out air is preferable, since reducing contact with air will slow corrosion. The most common household items with this function are zip lock bags, or any other air tight bag with non-abrasive surfaces, such as those made of polyethylene or Mylar.
Avoid polyvinyl plastic bags however, as they have chemical compounds that promote tarnishing. If you’re willing to spend extra, silver jewelry stores carry specialized bags and boxes that help prevent tarnishing. When storing, it’s best to keep silver jewelry in separate bags, away from other hard items that may scratch your precious Tiffany & Co jewelry’s surface. Avoid excessively humid areas, areas with direct sunlight, and other places where T&CO jewelry could rub up against other items. Do not store tiffany silver jewelry directly on chemically treated surfaces, such as wooden counter tops, since they contain chemicals that may promote tarnishing of your tiffany sterling silver. Ok, I am sure the above tips are helpful to you, and when you use those tips your Tiffany jewelry will keep beautiful and bright.
