The Diamond Dealers Club celebrated its 75th anniversary in style with a swanky party at New York’s Rainbow Room.

Music was provided by Vito & the Salutations, a ’60s doo-wop group that features DDC security director Rick Pettigano. Antwerp, Belgium’s HRD also presented jewelry from its awards competition. At a ceremony earlier in the day, the DDC honored members who had been with the club 50 years or more.

“We were founded by immigrants and by the sons of immigrants, and we continue to be a place where a variety of languages are spoken, but the common reference is always diamonds,” said DDC president Jacob Banda. “Indeed, in a world split by mistrust and suspicion, the DDC is a place of unity and peace.”

At the dinner, Dr. David A. Sampson, deputy secretary of the U.S. Commerce Department, toasted the DDC for its contribution to American business.

The DDC also gave Lifetime Achievement Awards to Kaushik K. Mehta, chairman of Antwerp’s Eurostar Diamond Traders; Serguei Oulin, vice president of Alrosa Ltd. and president of the Diamond Chamber of Russia; and Shmuel Schnitzer, president of the World Federation of Diamond Bourses. DDC secretary Sylvain Ringer was inducted into the Diamond Industry Hall of Fame.
