This extraordinary brooch was crafted by Wilhelm Lucas von Cranach c. 1900. “Tintenfisch und Schmetterling” (Octopus and Butterfly) currently resides at the Jewellery Museum at Pforzheim. The pseudo nouveau / victorian piece is set with diamonds, enamel, rubies, amethysts, topaz, and three baroque pearls. Can anyone find the ‘hidden’ element?
