At the heart of New York's Diamond District, Extell developed The International Gem Tower. This striking glass tower designed by SOM Architects is New York City's only commercial condominium designed specifically for the global diamond, gem, and jewerly industry. The industry center was conceived to provide services and amenities never before offered in New York's Diamond District, including state-of-the-art security, foreign trade zone designation, secure underground parking, and prime retail opportunities.
