In a sign of De Beers’ increasing comfort with doing business in the U.S., its executives’ U.S. trips are becoming more frequent.

De Beers marketing executives Dominic Brand and Janet Sussens recently visited participants in the Everlon program. In addition, Diamond Trading Company managing director Varda Shine was spotted at the 24 Karat Club Dinner in January.

Diamond Information Center spokeswoman Jamie Cadwell said Brand’s and Sussens’s visit shows how committed De Beers is to Everlon’s second year.

It should be noted that De Beers still has no official U.S. presence, and the company has said it has “no plans to change the way” it sells diamonds.
