I just bought the hanging heart earrings in mother of pearl. I saw them on fashionphile and thought they were so pretty so I ordered them and received them today. They are really pretty but I am very concerned because I'm unsure how I would clean them because there is not a Chopard boutique anywhere near me nor a Saks so I'm debating keeping them only for that reason. The care booklet says the stud can't be submerged for cleaning and I have no idea how to clean the pearl....
