Dating to the late 1800's  this antique chain is detailed with box like links. The craftsmanship is superb, each link forming a tiny work of art. The style is ornate and would be suitable for a man or a woman, perfect alone or worn with a pendant. The spring ring clasp appears to have been updated from the original
Round chains, linked at right angles alternatively, and wrapped above, below and on either side by gold loops .
