floral stud earings Diamond or CZ


I'm new to the group I brought some stud earing's from my local OP SHOP not sure if they are old but gave them a good clean , no marks hallmarks ,have done the magnet test ,they don't stick I know that doesn't mean to much as it could be some other metal But I will be taking them eventually to a jeweller to have them looked at , just wondering what any of you guys think . kind regards earings.jpg studs.jpg .
