Herringbone Fitted Choker #14 can last you a lifetime if the herringbone components are not twisted. Please make sure the necklace lays flat around your neck.
You can polish the choker gently with a polishing cloth for silver if it gets tarnished.
For a more rigorous cleaning; put the jewelry in a flat dish on top of a piece of aluminum foil (mat side up). Add some soda and hot water and let soak.
Make sure the silver is touching the foil.
