“We believe in the superior craftsmanship of our Belgian Master Cutters”
jean_claude_muller_x.jpgS. Muller & Sons founded in 1955 is now a world-renowned diamond manufacturer managed by the third generation of diamantaires led by Jean Claude Muller, the company’s CEO. S. Muller & Sons has an in-house diamond factory, one of the few that still remain in Antwerp, which is producing the now famous Hearts & Arrows Diamonds. The company’s involvement in Hearts & Arrows initiated with its relationship with Mr. Takanori Tamura, the inventor of the Eight-Star Diamond. While attending the Antwerp Diamond Trade Fair last February, our correspondents – helped by the Antwerp World Diamond Centre and S. Muller & Sons - took an opportunity to visit the company’s diamond factory, which resulted in the interview with Jean Claude Muller below.

Namibia-De Beers talks scheduled to end in June
isak_katali_x.jpgDe Beers and the Namibian government have been negotiating over a new diamond-sales agreement for quite some time now. The envisaged new deal would replace a 2007 agreement that allowed De Beers to sell the stones through the Namibia Diamond Trading Company (NDTC), a joint venture between Windhoek and De Beers. Namibia’s mines and energy minister Isak Katali told Rough & Polished’s Mathew Nyaungwa on the sidelines of a mining conference in Cape Town recently that the negotiations are now envisaged to end in June this year, if not earlier.

The gemmological education is very important for the industry to build a sound and strong edifice
bakul_mehta_x.jpgThe Gemmological Institute of India (GII) plays an important role in the local diamond industry, offering a broad range of services, which include diamond grading and certification, detection of diamond treatments and identification of synthetic diamonds, as well as research and gemological education courses highly popular and widely recognized in the trade in India and abroad having trained more than 5,000 students. The GII runs the only gem and diamond-testing laboratory in Mumbai fully equipped with state-of-the-art instruments. Bakul Mehta, Chairman of the GII, answers the questions from Rough&Polished in the exclusive interview below.

Let us go back to the magic – Stéphane Fischler
stephane_fischler_x.jpgOn February 1 to 3, Antwerp hosted the sixth Antwerp Diamond Trade Fair (ADTF) welcoming hundreds of buyers not only from the world’s established jewelry markets, but this time also from the markets, which until recently remained largely unexplored. In his address during the opening ceremony, AWDC President Stéphane Fischler said the ADTF was an important link in Antwerp's annual promotional and marketing campaigns. On the 2 of February, having arrived to Moscow to bid last farewell to Fyodor Andreev, ex-President of ALROSA, Stéphane Fischler gave an interview to Rough & Polished, in which, speaking about the Antwerp Diamond Trade Fair, raised a number of other issues of current concern to the global diamond industry.

Diamond Deposits in Yakutia

25.06.2012

Reserves and resources Allocation

The major part of the diamond reserves (about 80%) and almost half of the world’s proved diamond resources are located on the territory of the Republic of Sakha (Yakutia) in Russia. Despite the fact that the greater part of deposits lies in the extreme environment of the Far North and is characterized by complicated mining and operating conditions, the diamond grade of ores contained in Yakutia’s kimberlite pipes is normally higher while their quality is comparable with that of other deposits in the world, which makes their development economically efficient.

All the deposits located in the Republic of Sakha (Yakutia) belong to the Yakutsk diamond-bearing province with the Malo-Botuobinsky, Daldyno-Alakitsky, Anabarsky, Sredne-Markhinsky, Prilensky, Muno-Tungsky, Nizhne-Oleneksky and Morkokinsky diamond-bearing districts being the major ones.

Almost all the Yakutia diamond reserves (93.1%) are concentrated in the kimberlite pipes, and the alluvial diamonds make 6.9% of the approved reserves, with the inferred resources equal to 65% of the total inferred resources registered in the Republic. The diamond grade of the ores mined in the Republic (kimberlite pipes) is normally higher than in the deposits abroad, although by their quality the local diamonds are comparable to those mined at many similar mines accross the world.

As of January 1, 2010 the State Mineral Reserves Register of the Republic of Sakha (Yakutia) registered 47 deposits, including 17 kimberlites, 30 alluvials, with the total reserves over 1.0 billion carats in Categories А+В+С1 and С2.

The proved balance reserves life in the Republic is 25-30 years at the current mining level and is defined as satisfactory (Tables 1, 2).

mineral-Raw Material resources in the Russian Federation in 2010.” “Almazy. IATs “Mineral”, 2011, pp. 273-282.

The table was made by the author based on the data of the Programme “The Social and Economic Development of the Republic of sakha (Yakutia) up to 2025 and the Guidelines up to 2030”.

The development of the rough diamond basis is among the leading lines of activities of the Yakutia geological industry. In future, the diamond geological exploration will focus on localizing, exploration, evaluation and prospecting of potential diamond-bearing areas in the Yakutsk diamondiferous province and conversion of the inferred diamond resources into the commercial category reserves. increase in the diamond reserves begins to show on the proved kimberlite and alluvial deposits, those under exploration and deposits planned for prospecting, and in future, it should compensate for the utilized reserves.

At present, the real prospects in localizing commercial diamond deposits are connected with the Sredne-Markhinsky and Muno-Tungsky diamond-bearing areas, where new kimberlite bodies rich in diamonds can be discovered, as well as buried high-quality diamond placer deposits. Along with the elaboration of discovered deposits, it is expected to intensify the geological and geophysical exploration and the integrated studies are to be carried out along the fault zone containing ores.

It is also planned to increase the diamond exploration works minimum by 3.5% per year of the value of the diamonds mined in the Republic in order to replenish the utilized reserves and discover new promising kimberlite and alluvial deposits. This will allow provide the diamond mining industry with a dependable raw material base and increase the reserves for next 20 to 25 years.
