Early BLACK ENAMELED Double Trembler on cheap Pot Metal Brooch

Fabulous double trembler all done on gold plated pot metal. This actually looks like a Duette the tremblers are done with shiny black stripes inside and out in between the outside stripes are clear chaton stripes. The inside trembles a lot and is a cheap huge clear chaton center with small clear chatons around it. The four leaves are enameled shiny black and the other two are all done in clear chatons. Curly fronds done in clear chatons. Measuring 3 3/4” by 1 1/2”. This is quite large and has a bit of weight to it also. IT IS ABSOLUTELY STUNNING!
