This lovely filigree brooch looks Czech in origin but is unsigned. The material looks to be a gilt over brass, but there is gilt loss. The center stone is a large prong-set purple glass piece. Accenting this are 4 enamel insets with a purple slag enamel and 4 deep purple rhinestones.
The brooch is app. 1.75inches x 1.25inches. This is in very good condition with darkening to one purple stone and the mentioned gilt wear. The back works fine.
