Lovely old unsigned rhinestone dress clip we believe to be an unsigned Eisenberg, from the time period when they started producing jewelry to decorate their dress line; before the actual jewelry retail production began. We base this on the quality, diversity and size of the rhinestones, the item being age appropriate, the item being design appropriate; and the antique jewelry dealer we acquired this from previously had an identical clip of slightly later production marked as Eisenberg. This piece measures 2 & 3/4" long and is 3/4" across and is in good condition with the clip in good working order and the stone still brilliant. Great versatile size and design, on a silver metal backing that is also identical to that used in signed Eisenberg pieces.
