Jewelers Row, Philadelphia

Jewelers' Row, located in the Center City section of Philadelphia, Pennsylvania, is composed of more than 300 retailers, wholesalers, and craftsmen on Sansom Street, between Seventh and Eighth streets, and on Eighth Street between Chestnut and Walnut streets.
It is the oldest diamond district in America, and second in size only to the one in New York City. The Row is home to the country's oldest continuously operating diamond shop, wholesaler I. Gansky and Co., which dates to 1851, and many of the area's retail, jewelry making and appraisal businesses have been owned by the same families for five generations.
Jeweler's Row (Carstairs Row) was designed by builder and architect Thomas Carstairs developer for William Sansom, as part of the first speculative housing developments in the United States, and introduction of the Row house in the United States.
