Your piece has been given an added feature of an anti-tarnish coating, but tarnish is bound to happen. The easiest way to keep your piece shiny is to wash it regularly with mild soap, warm water, and towel dry. Even better yet - use a sonic jewelry cleaner. You can keep a polishing cloth on hand for an extra step. For protection when not wearing, store in an air tight bag with a moisture absorber. You can’t avoid tarnish, but these few simple steps will ensure shine for as long as possible.
