In 1903, Julia Munson became the head of Tiffany & Co.'s jewelry department. She played a pivotal role in developing the enameling techniques used in Tiffany's jewelry, although her significant contributions remained largely unrecognized at the time, as none of the pieces she worked on were signed. One notable example of their collaboration is the Peacock Necklace (circa 1906), designed by Louis Comfort Tiffany and crafted by Munson. The necklace showcases opals, amethysts, sapphires, and demantoid garnets, all set in intricate cloisonné enamel on gold.
