825 silver is a lower grade silver generally from the continent. Very common but unfortunately not worth very much. There are lots of good quality antiques our there which if they were sterling ie 925 they would be worth many times the amount of the poorer quality silver. The workmanship and detail is just as good but the manufacture price was lower. Regarding the jewelry, if it's new not worth a dickie bird. If it's old worth far less than it should be.
