Store jewelry in sturdy cases with soft, lined interiors to avoid impact against hard surfaces and scratching.
Scan your jewelry with a critical eye. Eliminate out-of-style, wornout, mismatched, never-worn and broken pieces.
Clean and fix any keepers that are tarnished or in disrepair.
Clean silver with silver polish or a jewelers cloth. Or rub the piece with toothpaste, using an old toothbrush to get into cracks. Rinse.
Clean gold, platinum and diamonds by dropping two Alka-Seltzer tablets in a glass of water and immersing the jewelry for about two minutes. Or soak for several minutes in a bowl of warm water with dishwashing liquid. Rinse and polish with a smooth, lint-free cloth or chamois.
Store like items together. Keep specialty items in their original boxes if you like, labeling the box's exterior. Storing silver pieces in felt jewelry pouches prevents tarnishing and keeps items ready to wear. (See 138 Store China and Family Heirlooms.)
Choose the best location and storage for your jewelry. A traditional jewelry box on a dresser can adequately accommodate smaller collections. Shallow dresser drawers outfitted with trays and organizers manage larger collections in style.
Protect valuable pieces of jewelry and items with great sentimental worth in an at-home safe or in a bank's safe-deposit box. Make sure you properly value and insure these items in case of loss.
Place jewelry in soft fabric pouches if no jewelry cases are available.
Store jewelry separately to avoid tangles and scratches.
Use tarnish-resistant cloth and cases to store silver.
Keep your jewelry boxes away from high heat and excessive moisture, which can damage some stones.
Consider purchasing a jewelry box with a lock and key for extra security.

That is a great post. Thanks for this valuable information. Jewelry keeping is an art which are time tested and it is important that they are maintained and secured as long as possible. Most of my family members knew of this art which had been passed from generation to generation.
