These are pearls from a 18K gold earring and necklace that my mother received as a keepsake. The earrings had large pearls (2 pieces). The necklace had small pearls (3 pieces). I don't know much about pearls, so I'm not sure what kind they are. Large size: Approximately 20mm (2 pieces) Small size: Approximately 20.04mm (3 pieces) The photos are everything. Please allow for some minor errors. Please refer to the photos for details. I would be happy if you could use them for pendant heads, necklaces, rings, etc., for handmade or custom jewelry. Please note that the colors may differ slightly due to the way they appear in the photos. Please refrain from purchasing if you are nervous or if you are looking for a perfect item, as these have been stored at home. Since I am an amateur inspector, there may be some oversights. We are looking forward to your purchase if you don't mind the details and understand.
