Proper Jewelry Storage
To maintain its quality and luster, make sure that your jewelry is stored in a closed box in a cool, dry place, away from heat and strong light. Try to separate the pieces individually to prevent scratches to gemstones and metals. You can also store your fashion jewelry in a fabric-lined case with separate compartments, or wrap pieces singly in soft tissue paper.
Clean your jewelry
For items that are dull and rusty, simply clean it with a soft cloth on a regular basis (once a month is a good rule of thumb). It's also applied to Sterling Silver pieces, but with a soft 100% cotton or a silver polish cloth. No liquids or solutions are necessary.
