WD Sues Diamond Growers over CVD Patents

A 9.04-carat round brilliant produced by WD Lab Grown Diamonds in 2018 using chemical vapor deposition.

The companies behind WD Lab Grown Diamonds have filed three lawsuits against competitors, accusing them of infringing patents for diamond synthesis and treatment.

The Carnegie Institution of Washington, a science organization, and M7D Corporation, which trades as WD Lab Grown Diamonds, took action Thursday again six companies that produce or sell diamonds made using chemical vapor deposition (CVD).

One of the complaints targets Pure Grown Diamonds (PGD) and IIa Technologies, which produces CVD goods for PGD. A second filing is against Mahendra Brothers, a De Beers sightholder, and its affiliate, Fenix Diamonds. The third suit takes aim at Altr, another lab-grown supplier, and its owner, R.A. Riam.

Carnegie invented and patented a version of CVD, known as microwave-plasma CVD (MPCVD), that can create a purer diamond because it doesn’t involve electrodes, which often contaminate the product, according to the lawsuits. It also patented a method for enhancing a stone’s visual characteristics through heat treatment at high pressure and temperature. M7D holds the license to both patents, the three similar lawsuits continued.

“The existence of the patents…are well-known in the lab-grown diamond industry, and in particular are well-known by lab-grown diamond manufacturers, importers and sellers,” Carnegie and M7D claimed.

Carnegie and M7D are seeking damages and a judgment declaring that the six companies violated their patents. The companies were not available for comment Sunday.

Petra Diamonds shares fall on lower diamond prices at flagship mine

Petra Diamonds

Shares of Petra Diamonds Ltd slid as much as 10 percent on Monday after lower diamond prices at its flagship Cullinan mine and an increase in net debt took the shine off higher half-year revenue.

The company has been trying to keep a lid on debt after heavy investments and a stronger South African rand had burdened the miner, which pays in rands and earns in dollars.

Petra’s net debt jumped to $557.2 million (422.06 million pounds) in the six months to Dec. 31 from $538.9 million as at Sept. 30. The company was forced to raise $178 million last May by issuing equity to cut its debt burden.

Rough diamond prices fell to $96 per carat from $140 per carat in the previous year at the Cullinan mine, which in 1905 yielded the Cullinan diamond the largest rough gem diamond ever found and now part of the Crown Jewels of the United Kingdom.

“The significantly lower realised Cullinan pricing and the impact on cashflow generation sees us take renewed caution,” said RBC, which cut the miner’s price target to 40 pence from 65 pence after the company’s half-year report.

Petra posted an 8 percent jump in revenue to $207.1 million, about 10 percent below RBC forecasts of $230 million, hurt by lower pricing at Cullinan. The company stuck to its production forecast 3.8 – 4.0 million carats for fiscal 2019.

Shares of the miner, which runs four mines in South Africa and one in Tanzania, were 8.5 percent lower at 41.12 pence.

Lucapa to Sell Large Stones

Lucapa Lulo diamond

Lucapa Diamond Company will sell six large stones weighing a total of 449 carats from its Lulo mine in Angola after an overhaul of the nation’s mining laws prompted it to delay the sale, it said.

The Angolan government introduced reforms to its diamond sector in the first half of the year to help boost foreign investment. Those measures included a new marketing policy for Angolan diamonds, and the option of offering goods for sale in locations such as Antwerp.

Anticipating the changes, Lucapa has been holding back a selection of large stones from previous sales, and will now sell them under the new policy, it explained Friday. These include six type IIa white diamonds weighing 114 carats, 85 carats, 75 carats, 70 carats, 62 carats and 43 carats, as well as a 46-carat pink diamond.

“The discussions with our Angolan partners regarding the policy changes taking place in the Angolan diamond sector have reached a stage where we are now able to plan for the sale of these large, premium-value Lulo diamonds held over from previous sales,” Lucapa managing director Stephen Wetherall said. “We look forward to marketing these exceptional diamonds as soon as the necessary arrangements are put in place to continue showcasing Angolan diamonds to the world.”

The decision to delay the tender for those stones had a negative impact on Lucapa’s first-half results, the company added. Its losses grew to $4.6 million for the period, versus a loss of $1.2 million a year earlier.

Even so, Lucapa’s sales rose 3% year on year to $15.9 million in the first half, while production for the same period climbed 15% to 9,566 carats. The average price of rough diamonds from Lulo rose 1% to $1,642 per carat. Rough-diamond inventory from the asset grew 61% year on year to 2,755 carats as of June 30, the miner reported.

Lucapa’s most recent sale of 2,531 carats of rough from Lulo fetched $2.5 million, achieving an average price of $985 per carat, the company noted.

De Beers, Botswana Prep for New Sales Deal

De Beers Botswana

Botswana once again finds itself at a crossroads. The sparsely populated, landlocked country is in a constant battle to ensure the longevity of its diamond industry.

Recognizing that diamond mining will not last forever, the government’s beneficiation program has sought to establish cutting and polishing, trading, and auxiliary services in an effort to diversify its industry — and economy — away from its reliance on the mining sector.

Beyond mining

De Beers, which counts around 59% of its production by value in Botswana, has played no small part in that effort. It did so initially by earmarking a part of its rough supply to be manufactured in Botswana, and today there are 18 sightholders with factories in the country. In 2013, De Beers moved its sales headquarters to Gaborone, meaning that its 10 annual sights were taken out of London, thus diverting traffic and diamond-related activity to the African city.

Furthermore, the establishment of the parastatal Okavango Diamond Company that same year gave the government access to 15% of production by Debswana, its joint mining venture with De Beers. That was the first time substantial rough sales from Debswana took place outside of the De Beers system.

The 2011 agreement that governed those developments is up for renewal in 2020, and negotiations are expected to begin in the coming year. For its part, the government is seeking to increase supply to local sightholders as a means of creating more jobs, newly elected President Mokgweetsi Masisi told Bloomberg in May.

Some question whether Botswana can handle more manufacturing, given that a few factories have closed in recent years. If profitability remains the biggest challenge facing manufacturers, Gaborone has yet to prove itself as a viable center for high-volume cutting. Perhaps De Beers can play a further role there, too.

The government will also likely want to increase the percentage of Debswana supply that Okavango receives. And it might want to renegotiate greater access to the large and high-value diamonds Debswana recovers.

Digging deep

Botswana has some leverage in the relationship with De Beers. It owns a 15% stake in the group, with Anglo American holding the remaining 85%. And the two are equal partners in Debswana and in DTC Botswana, which sorts and mixes production for De Beers and Okavango.

De Beers, meanwhile, brings to the table its mining expertise and budget. In 2010, it committed to investing $3 billion over 15 years in the Cut-8 expansion of the Jwaneng mine — considered the world’s most valuable diamond-producing asset.

That project is already the main source of ore at Jwaneng and is expected to  extend the life of mine to 2030 and by some 93 million carats. Studies for the viability of Cut-9 are under way, which would further extend the life of Jwaneng. A final investment decision on the project is expected later this year, reports a De Beers spokesperson.

De Beers could use the potential Cut-9 investment, as well as funding extensions at the Orapa and Letlhakane mines, as a bargaining tool in negotiations with the government.

African investments

De Beers walks a similarly fine line in other African countries where it operates.

In South Africa, it may have to reduce ownership of its local businesses from 74% to 70% under the new mining charter, as the government wants to see more local black economic empowerment (BEE) involvement. That said, De Beers is engaged in a $2 billion project to develop underground mining at the Venetia asset. From next year, Venetia will be its only mine in South Africa, as it plans to close the Voorspoed mine. It has already sold the Finsch, Cullinan and Kimberley operations over the past decade.

Meanwhile, in May 2016, De Beers signed a 10-year sales agreement with Namibia, in which it ceded 15% of local supply to the government and promised more diamonds to local cutters. The company subsequently announced major investments in its marine mining operations off the Namibian coast.

It’s that give-and-take that Masisi is hoping will result in a “win-win” for both parties as they negotiate their next long-term deal — especially given that so much of Botswana’s future diamond production depends on Jwaneng’s expansion.

“We have had a wonderful relationship with De Beers, and we expect that relationship to be even more cemented,” the president told Bloomberg in May. “The returns [from the Jwaneng development] are going to be realized in the period of the next deal. This is a marriage we’re after.”

Lucara Sells Two Huge Diamonds at $32M Tender

Lucara Tender Rough Diamonds

Lucara Diamonds have sold two exceptional large rough diamonds at the $32.5 million tender.

The tender included a 327 carat rough diamond that sold for over $10 million USD.

Lucara said the 10 stones ranging from 40.4 carats to a 472.37 carat rough stone a combined 1,453.06 carats, sold for an average price of $22,356 per carat.

The top seller was the 327.48 carat white diamond, which earned $30,900 per carat total $10.1 million.

Another exceptional size 472.37 carat light brown stone also sold but the miner has not publish its price.

Botswana Diamonds picks up high potential kimberlite pipe in South Africa

rough diamonds

Botswana Diamonds has been awarded the priority 2.5 ha Mooikloof kimberlite pipe concession. Using recently developed exploration techniques it will re-assess this high potential pipe.

The award of the Mooikloof Prospecting Licence is an important development for Botswana Diamonds.

Mooikloof was last prospected in 1986. The adjacent Oaks mine was owned and successfully operated by De Beers. The Oaks mine had a grade of 53 cpht at a value of $156 per carat.

The large flagship Venetia mine, operated by De Beers, is close by and in the same general geology.

Based on Botswana Diamond’s experience elsewhere, it suspects that past explorers may have systematically under estimated the kimberlite pipe size, grade and diamond quality of the Mooikloof kimberlite.

It will deploy state of the art exploration techniques to reassess the Mooikloof kimberlite, and maybe open another by passed kimberlite pipe development.

Botswana Diamonds has now received the Technical Economic Evaluation Report on the Thorny River Project.

The deposit is between 1.2 and 2 Mt, the grade is between 46 and 74 cpht and carat values between US$120 and $220 per carat.

The Technical Economic Evaluation Report indicated positive economics could potentially be achieved using the top end of the grade and value ranges, assuming additional kimberlite volume of similar grade and value can be defined with further exploration.

While not a Scoping Study as Botswana Diamonds had previously envisaged in the announcements dated 15 February 2018 and 21 March 2018, the Technical Economic Evaluation Report has provided the company’s directors with sufficient information to conclude that the Thorny River Project requires further investigation.

Consequently, the directors are considering the company’s various technical and commercial options, which will be studied simultaneously with ongoing exploration.

Drilling at Ontevreden confirmed the existence of a kimberlite pipe, but showed the pipe to be smaller than the previously indicated geophysical anomaly.

Given Botswana Diamond’s attractive priorities elsewhere, it now proposes no further work on Ontevreden.

“Significant progress has been made on our joint venture projects in South Africa,” comments Botswana Diamonds chairman, John Teeling.

“Analysis shows that a mine on the Thorny River deposit could be profitable assuming positive results from additional exploration. Now we must refine the volume, grade and value estimates while working on the mining model.

“But modern mineral exploration technology is not a magic bullet. Modern geophysics indicated a 0.7 ha pipe at Ontevreden. Our drilling confirmed a smaller pipe, which is not currently commercial”.

Petra Diamonds record output

Petra Diamond mine

Shares in Petra Diamonds climbed almost 8% on Monday after the miner reported a significant revenue increase in its third quarter driven by record production in the first three months of 2018.

The South African diamond producer, owner of the iconic Cullinan mine, which produced the diamonds for the British crown jewels, said revenue for the quarter ended March 31 climbed 44% to $172 million, from $119 million a year earlier.

Petra Diamonds saw third-quarter revenue grow by 44% after it produced and sold more gems.

The company, known for some major recent findings, attributed part of the revenue growth to the fact it sold 1,373,771 carats of diamonds compared to 1,069,886 sold in the same period a year earlier.

While production jumped 20% to a record quarterly volume of 1,194,947 carats, Petra said illegal mining at its Kimberley Ekapa Mining JV dented output during the quarter by restricted access to high grade dumps at the surface re-treatment operation.

It also said its full year 2018 revenue continued to be impacted by the inability to sell a blocked diamond parcel from it Williamson mine of about 71,000 carats. The shipment was seized by the Tanzanian government in September last year, as part of the country’s ongoing probe into alleged wrongdoing in the diamond and tanzanite sectors.

Chief executive Johan Dippenaar said the company’s focus would move away from volume targets to value optimization.

‘While we are very encouraged by the operational delivery against our long-term expansion plans, risks to performance continue to relate to increased volatility in the ZAR/US$ exchange rate, grade and pricing variability at Cullinan,” Dippenaar said in the statement, adding that the outlook for its Williamson mine as well as the blocked diamond parcel were also weighing on the company’s future.

Israel Gives $284M Boost to Diamond Trade

Israel diamonds

The Israeli government has pledged $284 million (NIS 1 billion) to guarantee bank loans to diamond companies in an effort to ease the trade’s severe credit difficulties.

A lack of credit is stifling growth, especially among the smaller firms that constitute about 70% of the Israeli trade, according to a special committee set up to investigate the sector’s challenges.

The team — led by Naama Kaufman-Pass, deputy director-general of the nation’s Ministry of Economy and Industry — released its findings earlier this month, highlighting several ways in which the industry had hit a crisis.

Banks’ perception of the diamond sector as high-risk has led to a decline in total lending to the Israeli trade from $2.5 billion in 2008 to about $1 billion last year, the committee said in its report. Financial institutions are also refusing to accept dealers’ inventory as collateral, while competition from India and Belgium has added further damage to Israel’s market position.

To this end, the government fund will back companies’ borrowing, meaning that if they fail to repay a loan to a bank, the state will pay. While the committee submitted the policy to Eli Cohen, minister of industry and economy, as a recommendation, the lawmaker said the government was set to go ahead with the program.

“We have decided to allocate another billion shekels over the next five years to the diamond sector through credit guarantees,” Cohen told an audience at the International Diamond Week in Israel last week.

In addition, the committee suggested the government provide money for the bourse’s newly launched innovation laboratory, put cash into bringing more diamond buyers to Israel, support efforts to develop e-commerce opportunities, and contribute to other projects to boost the industry.

“The committee identified the main hurdles in small businesses’ activities in the sector, and its recommendations offer a comprehensive response to its needs,” Kaufman-Pass said.

The diamond trade is an important segment of the Israeli economy, representing about 13% of total exports, and employing about 9,500 people, according to the report. However, the 2008 global financial crash led to a 27% slump in Israel’s polished-diamond exports between that year and 2016, with the Chinese market slump in 2015 also denting demand.

“Implementing the committee’s conclusions, alongside other steps, is essential, considering the crisis the sector has been through,” Cohen added in a statement. “Their purpose is to provide new tools to help deal with challenges in the trade and to ease regulation, thereby growing both production and exports.”

Shay Rinsky, director-general of the Ministry of Economy and Industry, set up the committee in September to delve into issues of credit and growth in the diamond trade and examine how to bring the industry forward.

Lucapa recovers more diamonds at Lesotho mine

Lucapa Diamonds

Australia’s Lucapa Diamond has announced workers at its 70% owned Mothae mine in Lesotho have recovered diamonds sourced from residual material and kimberlite stockpiles.

The company said the rough diamonds were recovered through the existing bulk sampling plant and infrastructure at Mothae, which has been refurbished ahead of schedule as part of a previously announced bulk sampling program.

According to the statement the largest rough diamond recovered in the test run is 6.6 carats.

De Beers Will Start Auctioning Other Mines Goods

De Beers Rough Diamonds

De Beers  will begin auctioning rough diamonds from other mining companies to provide a broader range of goods.

The company will pilot the new program this year, making it easier for customers to buy their entire supply in one place, Neil Ventura, De Beers executive vice president of auction sales, said on Monday.

“One message that’s come through from our recent customer engagements is a desire for us to develop our supply offering in certain areas, so that there is a fuller and broader range of material available for purchase,” Ventura said.

“Based on this customer feedback, in 2018 we will be testing the potential to grow our core rough-diamond sales business through making some purchases from third-party sources,” he added.

The diamonds will come from miners which De Beers has carried out due diligence, and will only be a small minority of the goods De Beers offers.
