Charlotte Rose Becomes First Woman President in London Diamond Bourse History
Historic Appointment Marks A Significant Milestone For Gender Representation In The Global Diamond Industry
The London Diamond Bourse (LDB) has elected Charlotte Rose as its new President, making her the first woman in the organisation’s 86-year history to hold the position. She is also believed to be the first female President of any diamond bourse worldwide, marking a landmark moment for the international diamond trade.
The announcement followed the LDB Annual General Meeting (AGM) held on 25 June 2026, where members voted in a new Council of Management.
Rose succeeds David Troostwyk, who served as President for two and a half years and will continue as Vice President. Wolf Rabstein has been appointed Treasurer, while Paul Koppelman has been re-elected as Executive Officer.
Reflecting on her appointment, Rose said:
“I am honoured that the Council of Management has entrusted me with the role of President. The London Diamond Bourse has been trading since 1940, and I am the first woman to lead it. I hope that one day such a fact will be unremarkable. For now, I see it as evidence that this industry is capable of change and that our members are ready to embrace it.”
The newly elected Council includes Lewis Malka, Howard Levine, Kathy Chappell, Anna Rogers, and Shadi Jin-Ziabee, alongside the office bearers.
Founded in 1940, the London Diamond Bourse serves as the United Kingdom’s principal diamond trading hub and is a member of the World Federation of Diamond Bourses. The organisation provides a secure, transparent, and regulated marketplace for the trading of diamonds and other precious gemstones.
