Silver is the queen of metals: gleaming and elegant, cool to the eye, sensuous to the touch. Silver jewelry is a classic gift that remains close to a woman's heart. More than merely decorative, it often carries with it the appeal of a tender sentiment or a lovely memory. And it possesses a sophistication that every woman understands. However, in selecting silver jewelry for herself, a woman should not forget that men place a high value on silver themselves. For that special man the perfect gift in silver might be a handsome pair of sterling silver cuff links, a tie bar, an I.D. bracelet, or even a signet ring. For a man, silver is a gift of distinction. Acquiring fine silver is one thing. Keeping it bright and beautiful is another. However, there's no mystery to caring for your fine silver jewelry. Just follow these tips:   Store your silver in a cool, dry place that is preferably airtight, to avoid oxidation.   Avoid direct overexposure to artificial light or sunlight for long periods.   Don't store directly on wood, which often contains acids that can affect silver's surface.   Never put rubber bands or plastic directly against the surface of your silver.   Store items in a tarnish-proof cloth, or in drawers with tarnish-resistant strips.   Store each item individually, either in its own soft pouch or in a separate compartment of your jewelry box. Do not store silver loose in drawers; scratches will occur if you toss your jewelry into a compartment or allow pieces to rub against each other.   If a piece of silver jewelry becomes tarnished, use a paste, liquid polish or a treated polishing cloth to restore its original luster.
