The Diamond Exchange Condominium

New York – September 17, 2026 -- The Financial District building that once processed most of the diamonds entering America is welcoming residents instead of jewelers. The ten-story Diamond Exchange at 14 Maiden Lane, completed in 1894, has been converted into nine full-floor condominium homes plus a commercial space, with pricing starting just under $2.6 million.

The building's oversized bay windows were built for diamond dealers, not daylight photos

Maiden Lane was once the center of the American diamond trade, and architect Gilbert A. Schellenger designed the building with some of the city's first oversized bay windows so dealers could inspect stones in natural light. More than 130 years later, those windows now flood each residence with daylight beneath ceilings reaching up to 12 feet 6 inches.
