Composite items consist of silver items as part of a larger ensemble with other materials. Necklaces with silver and coral beads strung on cotton thread for example require a different approach in cleaning and storing than a necklace made out of silver beads and chainwork. In composite items, the most vulnerable element is leading in storing and cleaning. This can be the thread or cloth a silver item is mounted on, or one of the other elements such as clove and coral.

Store items away from direct contact with air, for example in plastic zipper pouches. To avoid denting and scratching, wrap the jewelry in bubble wrap before you put it in the pouch. Write the contents on the pouch for future ease when you want to locate a certain item.
Cleaning silver should also be done with care. Do not use silver polish: the polish can get clotted in an intricate design like filigree and is hard to remove. In addition, it is not always clear what the silver content of a traditional piece is. The polish may react with the base metal and lead to disappointing results. Polish silver items with a polishing cloth without additions. If you store the jewelry away from air, the need for polishing will diminish significantly.
Some materials have qualities that require special attention. A lukewarm bath with a mild biological detergent can have excellent results on single silver items to clean dirt and grease, but will have devastating results on materials such as coral and pearls: remember that these are organic! The wood inside an amulet container will expand when soaked and shrink when drying, which may damage the silver cover and the wood itself. When the silver items are part of a composite piece, always familiarize yourself with the properties of each and every material before attempting any conservation at all.
