I received these from my mother, who told me they are genuine pearls. However, there is no box or certificate, only my mother's word, and she comes from a family with a discerning eye for pearls. They are approximately 5mm pinkish pearls, with two 3mm pearls as accents. The overall diameter is about 8.5 centimeters. I will protect them with cushioning material and send them via Yu-Packet.
