Cleaning gold vermeil

[meringuenests]

I've got a anklet for a Monica V and it's gone a bit dull looking. I can't find that cloth that came with it.
What can I do to make it shiny again?

Google’s recommendation attached, when pic loads

Thank you

They have a 5 year warranty so see if that applys.
If it's gold vermeil I've had some success with the baking soda /silver foil method.

The gold came off one of my MV rings, but they replaced it. Very good service.
