The Large Toggle Necklace is always a winner. This one has a dark matte patina, but there is a bit of shine glare in the photo. The brass ball chain is 36" long, and meant to be worn doubled, so it is about 18" long. Some women also like to extend the chain to its full length, keep the toggle in the hole, and wear long like a pendant. The dark patina is like the sky that only astronomers see. It is about 2 3/4" by 2 1/2".
