This 17" white fresh water pearl and light blue crystal necklace and matching earring set is made with 7 mm oval fresh water pearls and the 4 mm crystals. 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 the same pearls and crystals! Also on the necklace is a carved rose out of white mother of pearl pendant! It is 24 mm in diameter.
