For Sterling and Antique Brass jewelry, the best way to clean is with a polishing cloth or polishing cream.  Please keep in mind, if the piece has been "antiqued", cleaning may remove the antique look and feel of your piece, leaving a more lustrous finish. 

For matte finishes, brush with a toothbrush and light amount of toothpaste.

Please do not place your piece of jewelry in a solution.  If placed in a jewelry cleaning solution , the stones may be damaged.
