Rare Dinkelsbühl antique vintage German 935 silver red coral brooch pin

This incredible piece shows some tarnishing but is stunning in its detail and modernity years ahead of its time. Dates to the 1920s-1940s. Features a genuine red coral cabochon on a scalloped textured base and is constructed of 935 silver, a higher purity than 925 sterling silver that was in production in Germany decades before a version of it was patented as Argentium in the 1990s. Weight is 8.6 grams. Clasp functions perfectly. Please see photos for measurements in inches.
