This is a lovely Retro period 14k rose and yellow gold bow brooch retailed by Tiffany & Co., c. 1930s. The brooch is collet set with a faceted citrine. The front of the pin is yellow gold and the back is rose gold so as the back folds to the front to form the bow, the rose gold is visible. The clasp bears the maker's mark for Eckfeldt & Ackley, a Newark, NJ, company, together with "14k" and the back is stamped by Tiffany & Co., the retailer. The pin measures 1 3/4" x 3/4" and is in really excellent condition.
