These are ESTELLE diamond earrings ⟡.· The posts are made of gold and white gold, and the catches are resin. I only tried them on once after buying them. They have been stored in a dark place. They are almost new (^^) I also have the purchase certificate, but the store name is printed on it, so I will send it to you if you need it after purchase (*^^*) If you need a paper bag, I will include it, so please consider it♩ ܸ *The paper bag has some folds and scratches. Immediate purchase is welcome! Shape of earrings: Catch/Stud Included items: Box Scratches/Discoloration: None
