Diamonds

Johannesburg, South Africa

MINTEK, South Africa’s minerals science council, announced that it will be embarking on a geoscientific study to research the possibilities of origin-determination for rough diamonds.  The project is aimed at determining whether trace elements can be used to discriminate between diamonds from different geographical sources.  While MINTEK will first study South African diamond types, it foresees future international collaboration.

MINTEK will be working in conjunction with the South Africa Diamond and Precious Metals Regulator (SADPMR) on the project.  Ashok Damarupurshad, Strategist at SADPMR, further clarified the goal of geochemical fingerprinting for individual diamonds.  “If proven to be successful, diamond fingerprinting would help to reduce theft and illegal mining and help prevent ‘conflict diamonds’ from entering legitimate trade, which is the objective of the Kimberley Process Certification Scheme.”

A huge gemstone that could become the world’s largest polished round diamond has been found at the Letseng Mine, owned by Gem Diamonds, in Lesotho, southern Africa.
The diamond weighs 478 carats and is the twentieth largest ever found. Gem Diamonds said initial examination suggests it has a flawless center and could produce a 150-carat round-cut white diamond worth tens of millions of dollars.
"Preliminary examination of this remarkable diamond indicates that it will yield a record-breaking polished stone of the very best color and clarity," the company's Chief Executive Clifford Elphick said in a statement.
The stone would dwarf the 105-carat Kohinoor in Great Britain's Crown Jewels. The largest rough diamond found was the Cullinan, in 1905, which weighed 3,106 carats uncut.
