Alrosa unveils first unique Russian collection of diamonds

Rio Tinto (LON:RIO) is looking to reduce costs at its Australia’s Clermont Coal Mine, in central Queensland's Bowen Basin, driven by falling coal prices.

Credit Suisse announced Wednesday it recruited David Hammond, the well-known mining banker from Morgan Stanley, to head up the mining and metals efforts of the Swiss bank worldwide.

A prolonged slump in the global economy has put pressure on the diamond industry, forcing sellers to grapple with sliding demand, rising inventories and declining prices.

Rough diamond production for the second quarter of 2012 increased 6% from the corresponding period of 2011 due to higher grade ore, but decreased 28 per cent compared with the first quarter of 2012 due to lower grades and a planned processing plant shutdown.

New oil reserves could also create new centres of power and in the context of a general oil rush in Central and East Africa, the lack of clearly defined borders, especially in the Great Lakes region, poses significant risk for maintaining regional stability.

The largest pink diamond ever discovered, an 8.01 carat sparkler found earlier this year at Rio Tinto’s Argyle mine, in Western Australia, went on permanent display in a Melbourne museum Thursday morning.

Rio Tinto's long-standing Chief Financial Officer, Guy Elliott, will retire at the end of 2013 announced the miner on Thursday, along with a few other senior management changes.

The core teachers’ union of Zimbabwe has demanded the proceeds of diamond sales be spent on their wages and on improving current working conditions.

Canadian junior Kennady Diamonds Inc. announced Tuesday the plan of arrangement between the company and Mountain Province Diamonds Inc. is now complete, and KDI shares have commenced trading on the TSX Venture under the ticker symbol KDI.
