The chalcedony is a highly polished periwinkle blue and sets off the rich purple of the amethyst chunks beautifully. I've used jet black seed beads to weave the larger beads together; I think it adds a touch of drama. With its dangles and drops, the piece has a vaguely medieval look to it; VERY feminine, VERY romantic. One can just imagine Lancelot clasping it about the neck of the Maid of Astolot. The collar is about 17" long and closes with a sterling silver "S" hook. It's another unforgettably feminine necklace from SPARKLE PLENTY.
