This vintage 1940s Eisenberg Original fur clip with a floral diamante rhinestone design that is early, signed, and monumental in design, execution, and size, it is a treasure and my favorite flower in my jewel garden. The rhinestones are magnificent, incorporating marquise, pear, round and oval shapes in various sizes creates interest as well as maximum dazzle. This fur clip measures a whopping 4 1/2 inches in length and is signed Eisenberg Original and has the number 7, generally assumed to be the stone setter's personal mark, etched on the back. This piece is in outstanding vintage condition, especially for a piece that is 75 years old. A couple of the tiny chatons in the petals of the petite accent flowers have aged, the rest of them and all of the larger rhinestones are super sparkly. The pot metal looks great, Eisenberg was very finicky, their jewelry had to look like fine jewelry, and took great pride in the pewter look of the finished settings. The Eisenberg Original mark was used from 1935 to 1945 and based on research and the clip's pot metal base I believe this predates the US entry into WW2. On page 138 of Fabulous Costume Jewelry History of fantasy and fashion in jewels, by Vivienne Becker, 1993, originally published as Fabulous Fakes in 1988, she features a group of distinctive Eisenberg diamante clips similar in design that are described as, quote, reminiscent of 18th century grandeur. In 1942 pot metal was forbidden for use in jewelry, its components were critical in the industry of war, and costume jewelers substituted sterling silver until the war ended. This is a magnificent Eisenberg Original fur clip, it is a collector's dream and it has been a privilege to be its guardian for many years.
