Alrosa exhibits largest pink diamond ever found in Russia




Russia’s Alrosa the world’s top diamond producer by output in carats, has put together a collection of recently found large coloured diamonds, which includes a pink oval gem weighing 14.83 carats the largest of its kind ever found in Russia.
The diamond it was cut from a rough found in 2017 at the Ebelyakh deposit in Yakutia, rated by the American journal The National Jeweler as the best discovery of the year. Before it was mined, ALROSA’s largest pink gem had weighed 3.86 carats.
“Pink diamonds among the blue ones are considered to be the rarest and most precious of all, and the size and clarity of this specimen makes it one of the best to be discovered anywhere in the world in recent years,” Alrosa’s chief executive Yury Okoyemovsaid  in a statement. “I am sure that this diamond will be the most expensive in the history of Russia’s gem cutting industry.”
The largest stone in the collection, however, is a deep yellow asscher cut diamond, weighing 20.69 carats.
The largest stone in the group, however, was a deep yellow asscher cut diamond, weighing 20.69 carats. It was cut from a raw crystal with a rare honey hue, which weighed 34.17 carats, also mined in 2017.

Other diamonds in the collection include a pink-purple cushion-shaped stone, weighing 11.06 carats, recognized by the GIA (the Gemological Institute of America) as the largest of its colour in the world.

In the last year, Alrosa has worked on boosting revenue from selling rare, coloured diamonds where demand is stable, although it is a niche business.

According to market analysts, the average price for pink, yellow, blue and green stones has risen consistently by 12% a year over the last few decades, driven by consumers passion for something exotic and unusual. This means they are less affected by other factors driving general diamonds’ supply and demand.

Currently, the global market for polished coloured diamonds is now dominated by Rio Tinto and Anglo American’s De Beers. But state-controlled Alrosa aims to compete.

“The diamonds we are now exhibiting are completely unique, and each of them perfectly embodies the Russian art of gem cutting,” Okoyemov said. “We calculate that the huge potential of our coloured diamonds will very soon enable Alrosa to become the world’s leader in that market.”

The company noted its pink and yellow diamonds will be soon transferred to the GIA for certification.

Liqhobong lights up Lesotho



Firestone Diamonds has announced the recovery of a 70 carat white, makeable diamond from its Liqhobong Mine in Lesotho.

This follows after a 46 carat gem diamond that was recovered in December, sold for more than US$1 million at a recently held sale.

The 70 carat diamond was recovered undamaged and will go on sale at the next tender which is scheduled to take place during March 2019.

Paul Bosma, CEO, comments:

“The 70 carat stone was recovered in the northern, low grade part of the pit in Lesotho where the bulk of our mining will take place in the coming months.

“Although the market for the smaller stones has been under pressure, we’ve seen continued demand and good prices realised for special stones”.

ANGOLA’S ENDIAMA: WE WILL MAKE $1.5 BILLION FROM DIAMONDS THIS YEAR



Endiama, Angola‘s state owned diamond company, said it expects to make about $1.5 billion from carats sold in 2019, compared with $1.25 billion realised from 8.47 million carats sold in 2018, Rough & Polished reports.

Endiama, which produced 9.4 million carats last year, said in a presentation held at African Mining Indaba that it expects to produce 9.6 million carats in 2019. In 2018, the company was the world’s fifth largest diamond producer by value.

Late last December, ite was reported that in 2019, Angola will get a second diamond cutting and polishing factory. Neves Silva, the head of Angola’s state-run diamond company Sodiam, promised that the plant will initially be able to process 4,000 carats of rough diamonds per month.

 Currently, the Angola Polishing Diamonds factory is the only such facility in the country. The second plant, with an estimated cost of $10 million, “will start operating in August and will have a bigger capacity”, according to the same report.

CVD Diamond Ring HRD Antwerp Grades ‘World’s First Wearable CVD All Diamond Ring’

HRD Antwerp has graded what it says is the world’s first ring that is entirely made from a lab-grown diamond made by Dutch Diamond Technologies (DD).
‘Project D’, DD’s name for the ring, took a year to manufacture and was created in honor of the company’s 10th anniversary, HRD said.

“The ring was made from a large piece of a 155-carat rough CVD lab-grown diamond which was polished using laser cutting and traditional techniques into a ring which has 133 facets, compared to 57 for a standard brilliant cut,” HRD said. “The ring has a total weight of 3,865 carats. It wasn’t until 2017 that it became technically possible to grow large enough monocrystalline lab-grown diamond plates.

“This is not the first ring to be created from a single diamond. In 2011, Shawish, a Swiss jeweler, unveiled the world’s first wearable ring made from a single crystal of natural diamond. Additionally, another lab-grown ‘all diamond’ ring, called (RED), was conceived by the Diamond Foundry, but as far as we are aware, the production phase has not yet started.”

Ton Janssen, CEO of Dutch Diamond Technologies, said: “For our 10th anniversary we wanted to create something stunning that would highlight our innovative and high-tech techniques. I think we’ve more than succeeded with the one-off ‘Project D’ ring. It’s a true “European” ring: grown in Germany, cut in the Netherlands and graded by HRD Antwerp in Belgium. HRD Antwerp has a well-earned reputation for delivering a perfect grading system thanks to their sophisticated equipment and dedicated team.”

The quality and carat weight of CVD synthetic diamonds has increased significantly over the last 10 years, taking up to 5 weeks to grow a diamond plate of this exceptional size in a laboratory. Growing a diamond with the CVD process requires a heated mixture of hydrocarbon gas and hydrogen in a vacuum chamber at very low pressure and elevated temperatures (900-1200°), he explained.

“DD might be relatively new to cut diamonds for the jewelry market, but they have created an impressive ring for their 10th anniversary,” said Michel Janssens, CEO of HRD Antwerp. The outstanding cutting and polishing work has resulted in a brilliant light reflection which emphasizes the beauty of the ring.”

HRD Antwerp has thoroughly analyzed the ring and delivered the following grading results: clarity VVS2, color E, Fluorescence Nil, Polish very good and Symmetry excellent. A lab-grown diamond grading report is easily distinguishable from a natural diamond grading report by its green color cover, the lab added.
