London—After less than two years on the job, CEO of De Beers Brands Marc Jacheet has left the company.
De Beers Group announced his exit Thursday. He will be replaced by Sandrine Conseiller, who has spent the last eight years at Maus Freres Brands Group, which owns Lacoste and The Kooples brands, among others.
She will join the company Dec. 1, overseeing the company’s brands, including De Beers Jewellers and Forevermark, and investment in existing and new diamond markets.

Before that, she worked as group marketing and branding executive vice president for Lacoste.
Prior to her time at Maus Freres, she spent almost two decades in leadership roles at Unilever in marketing, general management, and auditing.
Conseiller holds a master’s degree in business management from NEOMA Business School in France and has an International Directors Programme certificate from INSEAD.
She has served as a board member and senior advisor at PPYarns, Carbios, and Raise Sherpas. She also received the Chevalière de l’Ordre National du Mérite (Knight of the French Republic) for her work promoting diversity and sustainability in business.

“I’m delighted to welcome Sandrine to De Beers. Her track record as a leader of iconic, purpose-led brands speaks for itself. She has consistently driven transformation and growth. But I am even more impressed by her passion and values,” De Beers Group CEO Al Cook said.
“Sandrine joins De Beers at an exciting time, as we grow the value of our 135-year old brand and share magnificent diamond jewelry with our clients around the world. I look forward to working with her.”
Jacheet, a former Tiffany & Co. executive, joined De Beers in April 2022 after the retirement of company veteran Stephen Lussier, who spent 37 years with De Beers.
At the time of his retirement, Lussier’s title was executive vice president of brands and consumer markets, but Jacheet joined the company as CEO of De Beers Brands, a new title at the time.
De Beers said he has left the company to “pursue other opportunities.”
Cook said, “I would like to thank Marc for his support and contribution during his time as CEO of De Beers brands and wish him great success in the future.”
