Vintage Art Deco Czech brooch, unusual dark red marbled art glass cabochons set in leaf design silver tone filigree

Large vintage Czech brooch with detailed leaf design filigree and brick red marbled glass cabochons. The cabochons and their settings have similarities with Max Neiger pieces, but I can't see enough features to suggest this is a Neiger brothers production. It is a really unusual piece though, perhaps suggesting a cross-over between organic Art Nouveau pins and the more classic Art Deco filigree Czech brooches.

This brooch has a length of about 2 1/4 inches and a width of 1.5 inches. It fastens with a simple C hook clasp and pin on the reverse. It is in very good vintage condition.
