Vintage Saltwater Pearl Necklace

This piece has 95 beautiful 8mm pearls ranging from very light pink (almost white) to a champagne color. The clasp is marked 14k w JMP intertwined. It's about 18 1/2" long. It reaches down past my clavicle so I was told that it is a Princess necklace. JMP stands for Jean Marie Poinot whom is a jeweler in Paris, France.
