The brooch is marked "Grossé 1962 Germany", a period when Grossé was designing costume jewelry for Dior. This feather-shaped brooch is typical of Grossé's modern, yet still elegant style of the 1960s. This is a distinctive period when jewelry was solid but not overloaded with details. Grossé is a famous German jewelry manufacturer that became especially popular in the mid-20th century. They collaborated with Christian Dior since 1955, producing high-quality costume jewelry.
When Grossé began selling jewelry in the Dior boutique, it was a huge success, as Christian Dior highly appreciated the quality of the jewelry and formed a partnership with Grossé in 1955. For the next 50 years, Grossé's company was responsible for the production of Christian Dior jewelry. Such a long-term collaboration with a licensee was unprecedented in Dior's history.
