Miriam Haskell, a jewelry designer, opened her own store in New York City in 1926. She produced costume jewelry of elegant artistic ability, ornate and beautiful designs using faux pearls, rhinestones, turquoise, shells, Bakelite and coral that were hand wired in brass and copper to create unique designs of flowers, animals and other organic materials. Miriam Haskell jewelry has been know through the years for its high quality workmanship, designs, and materials. The jewelry pieces were handmade and handset using goldtone metal, an antique Russian gold metal finish developed by Haskell and Frank Hess. Miriam purchased her beads from France and Italy with her crystals imported from Bohemia. During WWII, Haskell used alternative materials including plastics for patriotic designs. After the war, the designs became more vibrant, colorful and feminine looking, more elaborate, larger pieces and multi bead strands with pearls imported from Japan.
Frank Hess worked for Robert early 1940s, Haskell designing jewelry although, Haskell in her lifetime, supervised the production of all the jewelry pieces. The 1950s brought Haskell jewelry with incredibility elaborate designs using stones, pearls and beads and filigree in new and exciting ways. The business was purchased in 1954 by Morris Kinsler. In 1984, Sanford Moss became owner but the business was sold again in 1990 to Frank Fialkoff, who is still producing today, the Miriam Haskell jewelry of traditionally the same quality and originality that bears the Miriam Haskell name.
