Its primary focus is to achieve operational excellence and enhance value through a continued cost reduction discipline and extracting maximum diamond value through technological initiatives.

Corporate governance

We integrate sustainability into our core business practices, working to create economic value for the Group while delivering ongoing benefits to all our stakeholders.

Through our robust corporate governance practices, we are able to conduct our business responsibly, providing attractive returns to our investors and actively contributing to the societies in which we operate.

Our approach to corporate governance

The board is fully committed to the highest standards of corporate governance which it believes will support the long term success of the Company.

Though a British Virgin Islands (BVI) registered Company, Gem Diamonds has a premium listing on the London Stock Exchange. The Group’s commitment to robust corporate governance supports its ability to create sustainable returns for all stakeholders. In September 2014 the FRC published the revised UK Corporate Governance Code and is applicable to companies with accounting periods beginning on or after 1 October 2014. The Board agrees with and supports the Code, and the Gem Diamonds governance framework was amended accordingly. The Group is thus well positioned to introduce the necessary changes as required.

The Board is ultimately responsible to shareholders for the Group’s activities, its strategy and financial performance, for the efficient use of the Group’s resources and for health, safety, social and environmental matters. With the assistance of the Audit Committee, the Board, therefore, approves the Group’s governance framework and reviews its risk management and internal control process, which leads to a more effective Board and facilitates the Chairman’s leadership role.
