    Gemfields said Sean Gilbertson would leave as CEO and director on 15 July 2026 by mutual agreement with the board. The announcement came with a warning that lower ruby grades, security problems and unpaid VAT refunds at Montepuez in Mozambique would weigh on output and cash flow, and the JSE-listed share price fell to record lows the following week.

    David Lovett, Gemfields' CFO for eight years, was named interim chief executive while keeping his finance responsibilities, as the board started looking for a permanent replacement for Sean Gilbertson.
