This brooch is simply beautiful. The repetitive filigree pattern enhanced by sparkling marcasite stones make a simple but powerful statement. A smart Art Deco silver brooch that was made circa 1930. It is set with graded marcasite (iron pyrites) The intention was that the marcasite imitated rose diamonds and the silver imitated platinum. Likely a copy of a diamond and platinum brooch with all the hand set and milgrain detail of the real thing! Measures approximately 2” x 1.75”.
