Art Deco Marcasite Brooch Silver Chalcedony and Amazonite by Theodor Fahrner

This exceptional Theodor Fahrner Art Deco brooch exemplifies the bold geometry and striking contrasts of 1920s–1930s German design. The composition features two square-cut blue chalcedony gems and a rectangular-cut amazonite, enhanced by round amazonite cabochons and shimmering marcasite-set floral motifs. The oxidized silver mount provides dramatic depth, highlighting both the luminous amazonite and the brilliance of the marcasites.
