Jessica McCormack appoints former Burberry strategy chief as CEO

Luxury diamond jewellery brand Jessica McCormack has appointed Leonie Brantberg, formerly Chief of Staff, Strategy & Growth Projects at Burberry, as its new Chief Executive Officer.

Brantberg brings with her "significant luxury industry experience" having also previously been SVP Strategy at Burberry from June 2017 to October 2022, and also a member of the brand’s executive committee.

Prior to Burberry, Brantberg was an Associate Partner at McKinsey & Company from October 2011 to June 2017, where she was Co-Leader of Apparel, Fashion & Luxury Goods Practice in the UK.

Jessica McCormack, Founder and Creative Director of her eponymous brand, said: "I am so thrilled to have Leonie join the company at this exciting time. She brings with her such a wealth of experience, but more importantly to me, she represents the true JM woman.

"She’s smart, tenacious, and curious, and I think we will make a great team. Her expertise in strategy will be invaluable as we continue to grow this brand that I am so proud of."

Brantberg commented: "Jessica’s unique take on fine jewellery is exactly what women want today, and I’ve been obsessed with the brand since I was first introduced to it a few years ago. I am thrilled to be joining as CEO at such a pivotal moment for the brand and can’t wait to get started."

Jessica McCormack is known for its "exceptional yet wearable" diamond jewellery, which are often referred to as "day diamonds".

Over the last two years, the business has more than doubled in growth - going from £9 million in 2020 to £24 million in 2022, building a "passionately loyal client base" along the way.

Brantberg will bring her strategic expertise, luxury sector knowledge and long-term vision to the brand, to realise its creative and commercial ambitions and lead the business through the next stage of its growth.

Her appointment follows the summer announcement that Jessica McCormack will open its second London store at 140 Sloane Street later this year, a 1,300 sq ft unit previously occupied by Zadig & Voltaire.

Jessica McCormack’s first London store, at 7 Carlos Place in Mayfair, celebrated its 10-year anniversary in June 2023.
