C. 1950's - 1960's chunky, hand-wrought sterling silver biker chain, probably the best I've ever found in this jumbo paperclip link style. Very heavy and expertly crafted, with a solid and secure bypass clasp. The feel of this piece against the chest is so grounding and stabilizing. Unisexy and so effortlessly cool. Wear with everything, forever.
18" length, can be adjusted. Weighs a whopping 70 grams.
