Picture it: you are presented with the trademark aqua blue box from Tiffany and can't wait to tear off that white ribbon. The jewelry inside is stunning, of course. You wear your bling for awhile, then put your baubles away. Fast forward to a few weeks or months later and you find tarnish on your precious Tiffany jewelry. Hmmph. Clean very carefully to avoid damaging the pieces.
Polish tarnished sterling silver Tiffany rings or bracelets with silver polish -- the fine links of a necklace may not withstand the pressure. Tiffany makes its own polish or you can use another premium brand. Dab some polish onto the piece and rub gently but firmly using a soft cloth. Tiffany sterling silver jewelry is more likely to become tarnished than gold or gemstones.
Rinse your jewelry in warm water to remove the silver polish. Work carefully to avoid scratching any stones.
Put together a bowl of warm water that's sudsy from just a few drops of dish soap. Grab a soft cloth and gently wash your jewelry. Use a soft, clean toothbrush to wash away oxidation from crevices, but don't scrub.
Dry your Tiffany jewelry as soon as you have washed it. If you wait around to dry your bling, you won't damage it severely, but you might notice some spotting has formed on the surface.
