Green stone and golden metal necklace, bib style, 16-in length, purchased at Anthropologie. The darkest stone is like a jade green, and the lightest stone is like an opal color. Ring toggle clasp. Item is very good condition only worn a couple times. I don't remember what materials the necklace is made of, but it has a nice medium weight to it. Dimensions are: end-to-end length: 16 inches height in the center: 2 inches
