West German Green Marbled Art Glass White Enamel Brass Filigree Pendant on Natural Pearl Necklace

Very unique 1940’s hallmarked West German Brass filigree open work with white enameling pendant with prong set marbled green & white art glass cabochon surrounded by emerald and peridot green crystal rhinestones.  Pendant is on a natural pearl hand strung necklace.  Obviously not original to the peice but a very pretty addition.
