Like Diagon Alley in Harry Potter, the Diamond District is a world unto itself. Best experienced on weekdays, it's an industrious whirl of Hasidic Jewish traders, pesky hawkers and love-struck couples looking for the perfect rock. It's home to over 2600 businesses, at street level and on upper floors, cutting, polishing, appraising or showcasing all manner of diamonds. In fact, the strip handles approximately 90% of the cut diamonds sold in the country. Marilyn, eat your heart out!
