Natural Diamond Council (NDC) has announced the appointment of Amber Pepper as Chief Executive Officer, effective February 1, 2026.

A seasoned global leader in luxury brand transformation, Amber Pepper brings a wealth of experience in driving commercial growth, digital innovation, and consumer-centric storytelling across some of the world’s most respected fashion and retail brands, including senior roles at Tapestry, Farfetch, and Harrods. Most recently she has served as Chief Marketing and Customer Officer and Managing Director at luxury digital platform Mytheresa.

Pepper’s work has consistently focused on building emotionally resonant brands and connecting with Gen Z and luxury consumers across global markets. Her experience in leading omnichannel strategies and building high-performing teams will be central to guiding NDC’s next phase of growth.

In her new role, Pepper will focus on shaping a compelling narrative that reinforces the desirability of natural diamonds and drives measurable commercial outcomes. She will strengthen consumer demand and industry partnerships, while ensuring natural diamonds remain distinct and relevant in a competitive landscape. A key priority will be expanding digital engagement with younger consumers and using data-driven insights to create marketing strategies that inspire emotional connection and long-term loyalty. 

Sandrine Conseiller, Chair of NDC, commented: “We are delighted to welcome Amber as the new CEO of Natural Diamond Council. Her global perspective, commercial expertise, and deep understanding of luxury consumers make her an exceptional choice to lead the Council and galvanise the industry.” 

The appointment follows the announcement that current CEO David Kellie will retire at the end of this year. Since joining NDC in 2019, Kellie has overseen the Council’s re-brand from the Diamond Producers Association to Natural Diamond Council. He strengthened relationships across the industry and navigated the organisation through major challenges, including the COVID-19 pandemic.

We would also like to thank David Kellie for his leadership and contribution and wish him all the very best success in his new chapter.
