This is a pearl necklace I purchased on minne a few years ago. Materials: Freshwater pearls / 14kgf Top diameter: Approximately 8mm Chain length: Approximately 40cm No adjuster. It's the type that fastens with a round clasp. There is some discoloration at the connection points with the pearls, but it's not noticeable unless you look closely. (See image 3) I remember the original price was around 2500-3000 yen.
