Some of the best and most collectible Miriam Haskell jewelry was made in the first decades when Frank Hess was her head designer, and this page shows a wide selection of them. Frank Hess was the head designer from about 1926 to 1960 and his talent is unrivaled. In the early days of Haskell they put no identifying marks on their jewelry at all, no signatures or logos. As a mater of fact it was not marked until about 1947. Today the early unsigned pieces can be identified from vintage art work and advertisements, and by their wonderful detail, hand work and design.
