"From the mid-1930s through the 1940s, the collaboration of the American jewelry firm Trabert & Hoeffer with the Parisian house Mauboussin produced some of the most extraordinary high-style jewels of its time. Hollywood stars such as Claudette Colbert and Marlene Dietrich appeared on-screen and off flashing the firm's historic gems mounted in diamond-studded platinum settings. Even during the Depression and World War II, Trabert & Hoeffer Mauboussin prospered and expanded across the country not only by continuing to supply stylish custom jewelry to celebrities and socialites, but also by marketing more affordable ornaments. Its best-known invention was the Reflection line of semi-custom jewelry—"Your personality in a jewel." Crafted from interchangeable parts, it made a bold new moderne look available to a wider range of customers by allowing them to mix and match preconstructed parts with their own choice of gemstones."
