In the early 1930s, in the workroom of the famous Parisian jeweler Boivin, a young jewelry designer named Juliette Moutard created one of the most coveted pieces of jewelry in the world-the famous starfish pin-still sought after today by aficionados of fine jewelry. The starfish, created out of gold and encrusted with 71 cabochon rubies and 241 small amethysts, was distinctive because its five rays were articulated, meaning that they could curl and conform to the bustline or shoulder of the women who wore it. The House of Boivin made three of them. Two of the women who bought and wore the starfish were Claudette Colbert and Millicent Rogers. Obsessed with the pin after she saw it in the private showroom of a Manhattan jewelry merchant, Cherie Burns set off on a journey to find out all she could about these fascinating pins and the women who owned them. Her search took her to Paris, London, New York, and Hollywood. Both a history of fine jewelry coming out of Paris in the Golden Age and a tour through the secretive world of high-end, privately-sold jewelry, Diving for Starfish is a stylish detective story with a glittering piece of jewelry at its heart.
