A magnificent double strand of 8mm graduated to 9mm genuine white freshwater cultured pearls are expertly strung on double stranded silk thread with double knots between each pearl. The necklace is further affixed with a silver double row safety clasp. The inside necklace is 16 inches, the outside necklace is 17 inches. There is usually a 1 inch difference between the two strands to get them the nest perfectly.
