My silver jewelry line is a specific finish for wearable art.  It is a matte finish.  It is not supposed to be a shiny & bright.  My silver line is designed to be more natural, like the stones I use in each piece.  The silver is Argentium, which is a special silver that is tarnish resistant!  The best way to brighten the silver is a wash with baking soda and salt.  Simply lay your silver (even with stones or pearls) on a pan lined with aluminum foil, boil about one cup of baking soda and a teaspoon of salt, and pour the boiling mixed solution on top of the silver pieces.  Let stand for approximately an hour.  Then gently scrub with a soft toothbrush the baking soda solution in and around your piece of jewelry.  Rinse with cool water and dry carefully.  It works sooo well!!!  I don't believe in cleaning jewelry constantly...it is meant to be worn and loved!
