What an unusual piece! Henry Dankner and Sons started as a small family business, in operation from the 1960's to the 1980's. Their workshop was located in Manhattan, and they were largely known for their gold mechanical charms. Items were usually stamped with a "D" and wreath. The families first studio was in Budapest, and they moved to Manhattan after their factories were taken over by Nazi Germany. During its peak, the factory employed 27 workers. Its distributers included Cartier, Harry Winston and Van Cleef & Arpels. This vintage sea turtle brooch is made of solid 14 karat yellow gold. His eyes are bright prong set rubies, and he is signed. The clasp works very well, and there are no condition issues. The makers Mark on the back has the letter D surrounded by a wreath of leaves. The clasp is on the diagonal, and works very well. Since the shell is domed you could clasp this on a set of pearls and wear it as a pendant. From nose tip to tail he is 1 1/4 inches long.
Weight: 7 grams Measurements: Width of shell is 15.5mm and the pin is 1 inch long.
