How do I get a return or replacement? My ring arrived it is gorgeous but a stone is missing from it

How do you suggest I clean this bracelet on a regular basis? And do I have to take it off to shower?

To the seller - please advise what you mean by "brush it gently" ... what brush would be appropriate that would not scratch the surface? thank you.
