Necklaces tangle most easily when several chains are tossed together. For everyday storage, fasten each clasp and lay the chain flat in its own compartment or soft pouch. If you use a jewelry box, choose sections that keep pieces separated. A pendant can be placed beside its chain rather than left to twist around neighboring jewelry.
Hanging necklaces can work well when each piece has a separate hook, but avoid placing them where they can knock against a wall or catch on clothing. Keep jewelry away from damp areas and direct sunlight, which may affect some finishes or materials over time. A dry, stable place is a sensible default for most fashion jewelry.
Before storing a necklace, wipe away skin oils, lotion, and moisture with a clean, soft cloth if the material allows. Make sure the piece is fully dry, and follow any care instructions that came with it. Avoid sealing damp jewelry in an airtight container. A small routine after wearing can prevent knots and helps you notice loose clasps before the next outing.
