This necklace is 42 and would make a great necklace to knot and hang loose. The green Chrysolite and malachite with the lovely wine fresh water pearls make a beautiful color combination. This is an all natural necklace. When you touch it, it is cold and and so clean, such a good feeling. The closure is a sterling lobster claw. This necklace has good karma and feels lucky! From the High plains of Kansas.
