Peretti quickly rose in the jewelry field, receiving the 1971 Coty Award for jewelry design, and had her first appearance in "Vogue" magazine. In 1972 Bloomingdale's, one of New York's landmark department stores, opened a dedicated Peretti boutique. In 1974, she signed a contract with Tiffany & Co to design silver jewelry; her work for them was the first time Tiffany had sold jewelry in that material in 25 years. By 1979, she was the firm's leading designer. Her silver pieces were seen as "fun" and attracted a younger clientele. The introduction of silver revised the category of fine jewelry and, comparatively more affordable, became something women began increasingly buying for themselves as opposed to traditionally receiving as a gift. Peretti’s reintroduction of silver to the company proved so popular that in 2002, the company began raising prices simply to retain a sense of exclusivity for the brand.
