This fabulous chatelaine brooch features elegant horses in sterling silver with one large horse head on the left and two smaller horses on the right.  Although unmarked, this piece has tested sterling.  It is quite substantial!  The horse heads are outlined in bright blue chaton rhinestones.  The curled mane is adorned with clear chaton rhinestones and the large horse has a rich red rhinestone eye.  Black and red enamel detail the faces.  The large horse measures 2 by 3/4" and the smaller horse heads measure 1 by 1 1/4".  The sterling open link chain is a very nice weight and has no weak links.  The shortest chain measures 4 1/2" and the longer measure 5 1/4".  This horse head design is shown in Julia C. Carroll's Costume Jewelry 202 on page 52 as a variation of the 1943 Coro patent 135970 assigned to Adolph Katz.   However, this particular brooch was shown in a 1940's magazine with no attribution. So in all probability not Coro, just a lovely and well made copy of their popular design.  That being the case, this is a magnificent chatelaine brooch and will be a proud addition to any vintage jewelry collection and a great conversation piece pinned to your favorite sweater or jacket.
