Rare Lilly Pulitzer Necklace ! Very pretty!

Very beautiful Lilly Pulitzer necklace. I don't have its tags anymore, but I have never worn it since purchase ! So very new ! The clam/seashell is 3D (see last photo), very good quality craftsmanship! I love it but for two summers now, it has been sitting in my drawer. Time for it to have an owner who can show it off ! No major damage. Might have couple light marks here and there from being in the drawer with other jewelry. But not visible unless looked very closely. Pendant moved around.
