Silver marcasite pendant & earrings

My $10 items are 4/$20 (or $5 each in multi item bundles) Oval pendant with 925 marking. Complementing earrings do not show 925 therefore they are silvertone. Brand unknown. Could benefit from cleaning. Really pretty! Please also see my "Before You Buy", "Note To Buyers", "About My Closet" and other informational listings.
