This 16-18" Adjustable white and grey fresh water pearl rhodium necklace and matching earring set is made with 6 mm irregular oval fresh water pearls. Also on the necklace is a large oval Abalone pendant. It is 25 mm long and 18 mm wide. The necklace is strung on very strong jewelry wire and I use sterling silver findings. The earrings are made with sterling silver pins and wires using grey pearls and grey crystals!
