I believe it is .925 silver with a platinum coating to retard tarnish.
I have seen a few rings stamped 925 PT, these are sterling silver coated with Platinum to retard tarnish, I would think that a 925 PC mark would be the same. If the item is stamped only 'PC' or 'PCV' with no numeric purity, karat or Sterling marks, I'd say that the letters are a makers/manufacturers identity mark.

'PC' means that the diamond or gold ect. in the jewelry are real.
