    Black, Starr & Frost: Isaac Marquand established Black, Starr & Frost in New York City in 1810, creating one of America’s most renowned jewelry firms with a rich and colorful history expanding over two centuries. The company had many historical firsts, including displaying jewelry in their storefront windows, originating window shopping. The family-owned generational business was also one of the first to be traded on the New York Stock Exchange, created the first choker necklace, and invented the safety deposit box system and fireproof buildings so clients could safely store their jewelry. They were also the first jewelry store to open on iconic Fifth Avenue. One of many impressive achievements includes selling the Archduke Joseph Diamond, a 76 carat, D-color, internally flawless diamond, the largest near-perfect Golconda diamond in the world, setting three world records for the sale of a colorless diamond at auction. The company’s values and continued success have set a standard in the industry that will live on for years to come.
