This is a stunning necklace--you could wear it and nothing else to a party and people will line up to stare at it. I think it it circa 1950s but is in the Art Deco style. I guess it could also be called "industrial". The glass eyes are all perfect. Eighteen inches long, each station is 1 & 1/4" top to bottom by 3/4" in width. I have had this many years now--and it has never been polished. It looks like stainless steel, but is likely silver-plated brass. No brassing evident though.
