Vintage 50-60’s faux pearls, marked Japan, hand knotted, 2 strand, graduated sz

A Few fine scratches but these were worn often with short sleeve round neck sweaters and sheath dresses by my mother back in 50-60’s. Strands 20-23” plus 2.5” hooked to Silvertone fancy fastener. Largest faux pearls in center. Good condition for age. Shinier than photos show. Ask any questions.
