Matching the necklace that is also currently available at One Good Eye Silver (you can see the set in the last photo) I suspect that this wide, gorgeous piece might be Italian since it resembles similar examples from the best lines of the Peruzzi or Coppini Bros.
It is made up of crisply cast links with fruit and floral motifs whose patina adds dimension and depth to the design.
Very well creafted, a definite keeper, and a piece that can hold its own any day of the week, this is also a rather wide piece at just shy of 7" long (wearable) by 1 3/4" wide. It weighs 49.6 grams, is simply hallmarked "STERLING" and I would date it in the 1930s-40s. In excellent vintage condition with great patina.
