How to Care for these Earrings With quality jewelry, make sure each piece is stored separately. Store in a dry, clean place in a divided jewelry box or individual boxes. It is good to bring in your fine jewelry to a professional jeweler for cleaning once a year. Jewelry can be cleaned by hand using a liquid jewelry cleaner, found in jewelry stores, or gentle soap and water. Keep your jewelry away from harsh chemicals such as bleach, as that will harm and dull most fine materials. Keep your sterling silver jewelry bright and shiny by wearing it! The natural oils of your skin help keep it clean, and regular use will actually keep it healthier than sitting in the jewelry box! About Biddy Murphy Real Irish gifts from real Irish people!
