 Diamond Dealers Club DDC New York

The Beating Heart of the Diamond Trade

As the anchor of New York’s Diamond District, the  Diamond Dealers Club New York DDC is the largest and oldest organization active in U.S. diamond trade, and the most important diamond exchange in the United States.

​The Diamond Dealers Club (DDC) is proud to announce its plans to move to the International Gem Tower at 50 w. 47th Street.

“The International Gem Tower (IGT) is critical to the future success and stability of the diamond industry on 47th Street in New York. I believe that this new facility and trading floor will be an incredible benefit to our members,” said DDC President, Reuven Kaufman. “Our members will enjoy the modernity, prestige and value that IGT has to offer. We are confident that the Club’s presence will enhance the experience for IGT owners, visitors and tradesmen. Now is an excellent opportunity for DDC members to secure office space still available from Extell Development, the developers of IGT, and be in the same location as the DDC and other major companies in the industry.”

“We are excited to welcome the Diamond Dealers Club to the building,” said Gary Barnett, the founder of Extell. “Having the DDC at the International Gem Tower completes our vision for a modern industry center in New York.” The DDC will be located on the 11th floor, where members will have the opportunity to conduct their business out of a brand new, beautifully designed, open trading floor with state of the art technical facilities, relaxing cafeteria and break area, and views out of the gorgeous floor to ceiling windows.

“There were many people on both sides who worked tirelessly to make this possible,” Kaufman added. “Gary Barnett gave the DDC this incredible opportunity, made us feel welcome, and has been exceedingly gracious in his dealings with us. Secretary of the DDC, is an invaluable asset to the Club and was instrumental in bringing this opportunity to fruition. Raizy Haas, Senior Vice President of project management and development at Extell, has been a pleasure to work with in leading the effort to ensure that the new space will meet the unique needs of the DDC and its members. The DDC’s Officers and Board Members have dedicated themselves throughout this process to ensuring that our members are given the best opportunities to succeed in today’s market. DDC’s Managing Director, David Lasher, and General Counsel, William Lerner spent countless hours to make this deal possible and have worked diligently to ensure that the DDC remains the ‘Beating Heart’ of the diamond trade in New York, the epicenter of the diamond industry .”

The DDC is in the process of building its new trading floor at the International Gem Tower. We look forward to welcoming you at our new home.

Manhattan’s 34-Story International Gem Tower Now Open

High Rise Facilities:

New York Loan Company, one of the country’s most exclusive collateral lenders specializing in confidential pawn loans against gold, jewelry, diamonds, watches, fine art and entertainment memorabilia, is the first office condominium owner to open for business at Extell Development’s International Gem Tower (IGT) on West 47th Street in Manhattan’s famed diamond district.

This is the first East Coast location for the family-owned collateral lender, which has been in business as Beverly Loan Company in Beverly Hills, California since the 1930’s and is often referred to as “the pawn shop to the stars.”

“The International Gem Tower is the first of its kind in the Western Hemisphere, offering a rare opportunity for jewelry-related companies to own and prosper in an ultramodern building with extraordinary technologies and amenities,” stated Raizy Haas, the senior vice president of Extell Development Company. “Beverly Loan Company has a stellar reputation in the industry, and I know its East Coast counterpart, New York Loan Company, will serve as a valued resource to other building owners and the public at large.”

New York Loan Company’s location comprises nearly 1,400 square feet of sought after corner space overlooking 47th Street on the building’s third floor, part of its retail podium level. Advanced security features include biometric building access, high definition security cameras with data analytics, a controlled entry interlocking bulletproof door system, bulletproof glass, private offices with abundant natural light, and access to the building’s state of the art vault, where all collateral will be stored.

“My family built an incredible business in Beverly Hills for the past 75 years, and we had no immediate plans to expand,” explained Jordan Tabach-Bank, the CEO of Beverly Loan Company and its third generation owner. “The International Gem Tower offered a truly unique and compelling opportunity for us to consider a location in Manhattan where, until now, there was no resource for truly upscale confidential collateral lending. The building ensures a highly discreet and secure environment for our clientele, which is paramount, whether they are making a short-term loan, selling their goods outright or shopping for jewelry and watches at dealer prices.”

Designed by Skidmore, Owings and Merrill, the ultramodern tower was developed specifically for the global diamond, gem and jewelry industry. In addition to a cutting-edge security system, which includes iris recognition scanners at the lobby turnstiles, owners will also benefit from onsite underground parking and a private health and fitness center.

“The hallmarks of our success have been our tremendous respect for our clients and the safeguarding of their collateral, along with a unique ability to quickly make a loan of any amount,” Tabach-Bank noted. “We’re extremely excited about New York Loan Company’s opening and look forward to bringing our exclusive services to East Coast clients who previously had no such local resources at their disposal with the expertise to loan against everything from an original Warhol to a fancy colored diamond.”

Diamond and gem industry heavyweights including A.S. Diamonds, the Gemological Institute of America (GIA); Eurostar, Kuperman Bros. Diamonds USA, Leo Schachter & Company, Malca-Amit USA and Manfra, Tordella & Brookes are part of the impressive roster of buyer
