New York—The Diamond Producers Association now has a managing director for North America, naming former Van Cleef communications executive Kristina Buckley Kayel to the role.
Managing director is a new position for the DPA in North America.
The organization previously had a chief marketing officer, Deborah Marquardt, but she left in September after two years with the organization, as JCKOnline.com reported. The DPA declined to comment on the reason for Marquardt’s departure.

In a news release, the organization said that Buckley Kayel’s “unique background and extensive experience in strategic marketing, communications and digital leadership roles well position [her] to spearhead the DPA’s mission to restore, protect and promote the integrity and reputation of natural diamonds, especially among the younger U.S. consumer base.”
For the past decade, Buckley Kayel worked as the vice president of communications, the Americas for Richemont-owned jewelry brand Van Cleef & Arpels. There, her oversight included media, digital, public relations and educational platforms.
