Sterling six chain plaited 17 inch necklace made in Italy marked 925

This necklace is 17 inches long and consists of 6 chains of sterling silver woven or plaited into a 3/8 inch wide necklace. The clasp is marked FM on one side, Italy 925 on the other. The chains have no bends or problems and the necklace lays flat, in very good condition. This comes from an estate but looks like it was never worn.
