Herringbone Bib Choker #5 can last you a lifetime if the herringbone components are not twisted. Please make sure the necklace lays flat around your neck.
The Herringbone chain can become damaged if the components are twisted.
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.
