Vintage best sterling silver crystal & marcasite pendant necklace and earrings

best Sterling silver. All pieces are stamped 925 on the back. The pendant has a couple other marks that I can't make out. The chain is stamped 925 and Italy at the end. The chain is 20" L. The pendant is 7/8" H and 5/8" W. The dangle pierced earrings are 1 1/8" L. All have crystal center stones surrounded by marcasites . @ 1990's. I cleaned them with a polishing cloth but still a fair amount of tarnish. I ship same or next business day.
