    Marianne Ostier: Ostier, Inc. was one of New York’s leading jewelers for nearly three decades during the 20th century. The New York based company was founded in the late 1930s, after Oliver Ostier, a third generation Austrian court jeweler, came to America following the Anschluss of 1938. His wife, Marianne Ostier, was the driving force behind the original designs. She was responsible for numerous contributions to the world of jewelry, including the pincushion clip, the famed skin pin, and free-form jewelry, which was no doubt influenced by her background as a sculptor. Marianne Ostier’s accolades include the Diamond U.S.A. Award and the Diamond International Award for design excellence. She was the first life-time member elected to the Diamonds-International Academy, the hall of fame for modern jewelry designers, and she represented the United States at the Art in Precious Jewelry exhibition at the Finch College Museum of Art in 1966, which featured the work of the foremost designers of ten countries. Among the artists, in addition to Mrs. Ostier, were Georges Braques and Salvador Dali. The company was closed in September of 1969 following the death of Oliver Ostier. Today, Marianne Ostier is a name famed for original design and superb bespoke craftsmanship.
