These are pearl earrings I inherited from my grandmother. The pearl part has been authenticated as genuine, but the type is unknown. There are no hallmarks, so they are recommended for those who enjoy them as accessories. They are recommended for those who understand that they have been stored by a private individual. Please refrain from purchasing if you are sensitive to such matters. Regarding the size of the pearls: The top two are approximately 2mm in diameter, and the bottom one is approximately 5mm in diameter. Please understand that there may be some error due to amateur measurement. Please read the profile before purchasing. Pearls, pearl earrings, accessories
