Protective Coatings and the Care of the Cuff
All our warm metals: copper, bronze, and brass are sealed with a professional coating.*
This coating protects the finish or patina of your piece from tarnishing. If you protect the coating from chemicals such as hairspray and hand sanitizer and other extreme conditions your jewelry's appearance should be the same indefinitely.
On the backside of the piece the coating protects the metal from the oils and acids of your skin. This helps reduce the chance of oxidation products from the metal being deposited on your skin.
(* Some small pieces may not be sealed so that they can develop their own patina. Ask about sealing.)
