Art Nouveau Pin Sash Buckle Lily Flower Brooch Antique Jewelry There are many fabulous features about this large and gorgeous Victorian brooch. The most prominent features are that it is French; it was made during the Art Nouveau period ( 1890-1910 ) ; It is yellow gold washed over brass with large Lilies in full bloom; and finally, the glass stone accents are rare French glass. So rare, in fact, that there are probably only half a dozen antique dealers in the US who could tell you what these glass cabs are. The large oval glass cab in the center is very impressive and compliments the yellow gold color of the gold washed brass nicely. The glowing green glass is a type of French Gripoix satin glass that I have coined as Kryptonite glass. In more recent years, when most people think of Gripoix glass, they think of a glass that looks quite different. From the mid to late 1800s, France was truly experimenting with glass, hoping to compete with the Bohemia region and Italy in quality and uniqueness. The color was accomplished by adding large amounts of copper oxide to a rich silica mix that makes the glass satin smooth. The glowing bright green glass was mixed with silver to achieve a dichroic effect. Both colors were mixed separately, then poured and mixed in the mold to create the mottled look that in the end, looks like something that came from planet Krypton !  This brooch is very weighty at 42 grams and measures 3" long x 1 3/4" tall. The French Gripoix glass cab at the center is in perfect condition and it measures 3/4" tall x 5/8" wide. There are two smaller matching glass ovals that are 1/4" long. All of the cabs are set in custom made smooth bezels. The lilies have a rose gold wash on the leaves.  This large sash buckle style brooch is in fabulous condition for age with no chips, scratches, or dings. It has the original old C clasp, bar, and hinge and it is not signed. The brooch is very nice and clean and there is no greening or grime. The brooch still retains the original old patina and only the relief areas have been professionally lightly polished. IMO, this is a drop dead gorgeous Victorian brooch with some of the rarest glass on the this planet !
