Thie is a Czech brooch from the Art Deco Period - probably made in Gablonz by an unknown maker. It has a large green centre stone and smaller ones - all claw set. The conch shaped metal pieces are mounted on a filigree base - and the metal work would have been gold plate on brass. The gold plate has aged! Full details on my web site - www.gillianhorsup.com price £95 reference 2911 C35/8. These brooches are so scare in an undamaged state that I was glad to get this one!
