Miriam Haskell was an American designer of costume jewellery. With creative partner Frank Hess, she designed affordable pieces from 1920 through the 1960s. Her vintage items are eagerly collected and her namesake company continues.

Miriam Haskell jewellery was worn for publicity shots, films, and personal use by movies stars Joan Crawford and Lucille Ball, as well as by Gloria Vanderbilt and the Duchess of Windsor. Crawford owned a set of almost every Haskell ever produced, from the 1920s through the 1960s.

Her vintage pieces can command high prices from collectors. However, her jewellery was seldom signed before 1950, it was her brother Joseph Haskell who introduced the first regularly signed Miriam Haskell jewellery.
