Art Deco Czech brooch. It features a prominent rectangular, cut-corner cabochon light green molded glass, chrysoprase, or faux jade. It has faint molded detail lines running across the face. The setting is decorated with a frame of green enamel work fashioned into delicate leaf and floral patterns at the corners. Accent Settings Interspersed along the top, bottom, and sides are small square and round bezel-set rhinestones or glass cabochons in shades of teal and emerald green.

The back of the brooch provides excellent clues that confirm its age and origin as a piece of 1920s to early 1930s European. It features an open "C" clasp.

The frame is a stamped brass filigree panel.

• Lack of Mark: As is common with the vast majority of Czech production from the Jablonec region (including works by the Neiger Brothers), the piece is unsigned and does not bear a country stamp. Many of these pieces were originally tagged only with paper labels or stamped on a hangtag that has long since been lost.
