I think you also posted this somewhere else. Not very expensive freshwater. Depending on the paint, you can try nail polish remover to make it look more like you want....but full removal will be very time consuming. Look on EBay, under used & see if you can find something that looks like a replacement...... (Always read reviews for sellers.). My guess that $30-40 for large freshwater pearls even with a nicer clasp will replace these....you could donate these to a local thrift store.....someone else might love them!
