While Mark Summers joins as group CFO from Anglo American.

London-based gemstone miner Gemfields has announced senior management changes with the promotion of Dev Shetty to chief operating officer and the appointment of a new chief financial officer from Anglo American.

Shetty joined the company in 2010 as group chief financial officer and has been instrumental in the turnaround of the Gemfields, improving the cost structure, tax profile and implementing key strategic and operational decisions.


He will continue to report to the group chief executive, Ian Harebottle, and remain a member of the board of Gemfields plc.

The company has appointed Mark Summers to replace Shetty’s role as chief financial officer, starting immediately.

Summers qualified as a chartered accountant in South Africa, completing his articles at Coopers & Lybrand before joining Anglo American’s Corporate and International Finance Department.

He has gained experience in a variety of roles covering auditing, mining and financial institutions over the past 18 years for both publicly listed and private companies and is well known and respected within the mining industry.

Ian Harebottle, Gemfields’ chief executive, said: “As Gemfields continues to grow and develop, various changes are required within the group to ensure that we remain well positioned to manage our momentum.

“To this end, changes have been made to strengthen the management team and I am confident that these new appointments will support Gemfields’ ability to deliver on its current growth plans. I have no doubt that Dev is the right candidate for the role of COO within Gemfields.

"His natural entrepreneurial talent, leadership skill and technical abilities have been clearly demonstrated over the past few years. Similarly, having worked with Mark in the past, I consider it a privilege to welcome him into the role of Gemfields CFO. Mark brings with him value and experience that will help position Gemfields for continued growth.”

Harebottle was named a Business Big Shot in the 2012 Professional Jeweller Hot 100 on Tuesday September 4.
