NWOT - Necklace and Earring Set

New in box and never worn is a beautiful necklace and earring set. Earrings are for pierced ears, oth pieces are marked with a diamond monogram (not sure what that means) and they have tags in th box that say Swarovski but I am not sure f they are or not. What I do know is they sparkle like crazy when the light hits them.
