Hello, We retail and take part in shows and now import jewelry from Thailand India and often from Italy, mainly we are into high quality sterling silver jewelry with comteporary designs. Can some one help me in seperating the following finishing on sterling silver peices: (1) Peices with Rhodium plating (2) Peices with .999 silver coating (3) Peices with anti tarnish coating on silver plating How can one consider the polish/finising done is perfect and not overpolished or little underpolished? Is there a definite color difference for rhodium plated/non rhodium plated/ silver plated on sterling silver ? It is often difficult to find out the kind of coating/plating done on sterling silver.
