Princeton University is tapping the expertise of the Gemological Institute of America (GIA) in gemological research and the analysis of optical centres to evaluate how to use the unique properties of diamonds to create a highly secure communications network. The GIA said in a press release that a research paper, published in the July 6 issue of Science magazine examines how colour centres created by replacing two carbon atoms with one silicon atom in the crystal lattice of a synthetic diamond could be used to store and retransmit information in a quantum communications network, that would allow for the transmission of information between physically separated processors. GIA Research Associate Lorne Loudin, one of several co-authors of the article, used instrumentation and techniques...
De Beers announced that it had provisionally sold $575 million worth of rough diamonds in its 5th sales cycle of this year. This is a 3.8 percent increase over the $554 million actually sold in Cycle 4 this year and is 6.3 percent over the $541 million actually sold in Cycle 5 of 2017. De Beers CEO Bruce Cleaver said, “Sentiment in the diamond industry’s midstream is positive following the JCK Las Vegas trade show at the start of the month, and we continued to see good demand for our rough diamonds across the product range.”
Global demand for diamond jewellery grew 7 percent in dollar terms over the first quarter of this year in a year-on-year comparison with 2017, according to research conducted by ALROSA. The miner said the growth could be attributed to a combination of increased consumer demand and the strengthening of other currencies against the dollar. The Asia-Pacific region recorded the strongest growth at 11 percent, mainly due to growth in mainland China along with stronger demand in Hong Kong and South Korea that was fuelled by increased tourist traffic.The Asia-Pacific region accounted for 20 percent of global diamond jewellery demand in 2017. US and Canada sales grew by 5 percent. ALROSA sees this as significant as the US accounted for 53 percent of global demand in 2017. Japanese demand grew by...

ALROSA announced it had sold 111 large gem-quality diamonds weighing a total of 1,725 carats for $10.5 million at its auction in Dubai from May 27 to June 14. Each individual diamond weighed more than 10.8 carats — what ALROSA calls ‘special sizes’. Winning bids were placed by 32 firms from India, Belgium, Israel, Russia, the United Arab Emirates and the United States. The auction was the third this year. "The auction has concluded with excellent results for us, with the starting price being almost doubled. This once again confirms that diamond market participants are still interested in our products. We plan to hold the next auction in Dubai in October-November this year," said Evgeny Agureev, Director of the United Selling Organisation (USO), ALROSA’s rough diamond sales arm.
The Antwerp World Diamond Centre (AWDC) announced that its Scientific & Technological Research Centre for Diamonds (WTOCD) has developed a technology that fully automates the diamond polishing process and opens up the possibility of diamonds once again being polished on a large scale in Antwerp. According to a AWDC press note, FENIX, the new, fully automated technology, which has been 10 years in development, enables diamonds to be polished between 10 and 20 times faster than the current manual system. A stone, that would typically consumer and entire day in processing, can now be polished in one and a half hours, the AWDC said. AWDC Chief Executive Ari Epstein commented, “This discovery fundamentally changes the diamond polishing process. Today’s wages simply make it too expensive to...
French luxury group LVMH Moët Hennessy Louis Vuitton has launched a dedicated jewellery section on its online retail portal 24sevres.com. The web retailer, which sells fashion items from LVMH’s own labels along with those of competitors like Italian brand Valentino, said the dedicated jewellery section would feature product from 13 brands. Prices for jewellery will range from $90 to $2,500. A study by Bain found that the jewellery segment grew faster than any other in the luxury goods sector barring shoes, clocking a 10 percent rise in constant currencies to €17 billion ($19.64 billion) in 2017. Rival Richemont, which owns the Cartier brand among others, is also boosting its web presence as high-end jewellery and watches increasingly find customers online. Richemont’s online retailer Yoox...
The Zimbabwe Consolidated Diamond Company (ZCDC), the state-owned entity that now controls all diamond mining in the country, is looking at securing $200 million in foreign direct investment while also ploughing in another $200 million from its own diamond sales earnings to bring the country’s rough diamond output up to 10 million carats a year by 2023. Stating this, ZCDC Chief Executive Morris Mpofu said that the strategy, contained in the company’s Diamond Value Management (DVM) plan, will primarily target exploration given that Zimbabwe’s easy-to-mine alluvial deposits have been depleted. Thus apart from the famed Chiadzwa diamond deposits in Marange that are currently being exploited, the ZCDC would look at other areas in Chimanimani as well as known kimberlites in Chihota and Mwenezi...
