State-controlled gems producer, the Zimbabwe Consolidated Diamond Company (ZCDC), has appointed industry veteran Dennis Mtombeni as its new chief executive officer, as part of a broader leadership transition plan.
Mtombeni will take over from Douglas Zimbango, who is set to step down on June 30.
In a statement, ZCDC said the changes were part of a structured succession process aimed at ensuring continuity at the state-owned miner.
Before his latest appointment, Mtombeni had served as CEO-designate for one month.
The company said: “In line with its structured succession planning process, the board is pleased to announce the appointment of Mr Dennis Mtombeni as CEO-designate effective June 1, 2026.
“During June 2026, Mr Mtombeni will work closely with Mr Zimbango to ensure a seamless leadership transition. He will assume full responsibilities as chief executive officer with effect from July 1, 2026.”

Mtombeni joined ZCDC in 2017 and has held several senior roles within the company, including mine manager, general manager of operations, and acting chief operating officer since 2024. Before joining ZCDC, he worked as mine manager at River Ranch Diamonds and Pickstone-Peerless Gold Mine.
Outgoing CEO Zimbango joined ZCDC as a non-executive director in 2022 before being seconded to lead the executive team in January 2024.
Zimbabwe consolidated its diamond mining operations under ZCDC in 2016 to improve transparency.
Mtombeni assumes leadership at a difficult time for the global diamond industry, which is battling falling prices amid the rapid growth of synthetic diamonds on the international market.
He is expected to spearhead strategies to help the company navigate the shifting dynamics in the gems sector.
