Two diamonds weigh over 100 carats each found in eastern Angola’s mine

Angolan rough diamonds

Dundo, Angola. Two diamonds, one 131-carat and the other 133-carat, were found in Angola’s Lulo mine in eastern Lunda Norte province, national diamond company Endiama announced here Friday.

The white colored gems were found in block 46 and 21 with more than 100 carats discovered in that mine, according to a note from Endiama.

Since the beginning of its exploration in 2010, the Lulo mine is known for its rare and high quality diamonds.

The mine’s blocks 6 and 8 are responsible for the production of 13 of the 15 stones with over 100 carats from Lulo mine, including the largest diamond ever found in Angola in 2016, with 404.2 carats.

The Lulo project, with a concession area of 3,000 square km, is operated within the scope of a partnership in which Endiama holds 32 percent, Lucapa Diamond Company Limited 40 percent, and the operator Rosas & Petalas 28 percent.

Botswana Diamonds shares good news from Thorny River

Thorny river diamonds

Botswana Diamonds has announced that eleven diamonds and abundant kimberlitic indicators were recovered from drill samples at the recently discovered River Kimberlite pipe at Thorny River in South Africa.

John Teeling, Chairman, commented:

“The recovery of so many kimberlitic indicators and in particular diamonds, which are very rare to recover in small sample narrow reverse circulation drill holes is highly encouraging and bodes well for the potential commerciality of this exciting discovery”.

Following a detailed ground geophysical programme in October 2020, 6, six-inch percussion reverse circulation holes were drilled into the newly discovered River Kimberlite pipe.

A combined total of 39.5 m intersected kimberlite while an additional 55 m intersected a weathered kimberlite breccia.

Samples from these holes were taken at one metre intervals and twenty of these totalling about 500 kg were selected and submitted to an independent processing facility for assessment through screening, dense media separation and hand sorting.

11 Diamonds, 172 G10 pyrope garnets, 623 G9 pyrope garnets, 555 eclogitic garnets, 438 chromites and 268 chromium diopsides (clinopyroxene) were recovered at sizes between -1.0+0.3mm.

Recoveries of a specific mineral species were capped at 20 grains and thus this picture is a snapshot of the overall sample indicator content. Importantly, all the samples contained abundant kimberlitic indicators.

The diamonds are all notably of good colour and clarity and are of commercial quality and in high demand by the market. The diamonds were not weighed as the sample size was small and they are not representative of a possible population.

Pyrope garnets are common in peridotite xenoliths from kimberlite pipes, some of which are diamond-bearing. Pyrope found in association with diamond commonly has a Chromium Oxide content of three to eight percent which imparts a distinctive violet to deep purple colouration.

These are called G10 and G9 pyrope garnets. Eclogites typically result from high to ultrahigh pressure metamorphism of mafic rocks at low thermal gradients as they were subducted to the upper mantle in a subduction zone.

Garnets found in eclogitic xenoliths tend to have a deep orange colour. Diamonds in kimberlite come from both peridotitic and eclogitic xenoliths so the abundance of both types of garnet in this sample is noteworthy and this is supported by the recovery of diamonds from a relatively small drill sample.

Of significance too is that these diamonds are all of good colour and clarity. The next step is a detailed core drilling programme which is planned for the dry season.

Christie’s Online Jewelry Auction Sells Out

Christies della Valle lemon earrings

Christie’s garnered $799,125 from its online sale of jewelry by designer Michele della Valle, with 100% of items finding buyers.

The top lot at the auction was a pair of yellow sapphire, tsavorite garnet and diamond lemon earrings, which went for $75,000, smashing its $10,000 high estimate, Christie’s said last week. Another set of earrings — containing 52 round and 12 baguette-cut diamonds weighing a total of 1.55 carats, tsavorite garnets, and red agate beads — also soared past its upper valuation. The pair, designed to look like cherries, brought in $37,500, well over its $6,000 estimate.

A number of emerald and tourmaline pieces also fared well. A brooch featuring round emeralds and cabochon green tourmalines sold for $37,500, well above its estimate, while a pair of earrings set with round, oval and marquise-cut emeralds fetched $25,000, nearly four times its high valuation. A square step-cut, 13.25-carat orange tourmaline ring, surrounded by cabochon green tourmalines and diamonds, brought in $23,750, against a high valuation of $6,000.

“With a background in opera and the arts, della Valle’s aptitude for creative output knows no bounds,” said Caroline Ervin, a specialist for Christie’s jewelry department. “For decades, della Valle has delighted jewelry collectors and fans alike with his bold and colorful creations. His unexpected and whimsical creations offered in our sale were met with enthusiasm from Christie’s clients around the world.”

In total, Christie’s offered 65 pieces by the designer, with bidders from 24 countries participating in the auction.

Who wins and who loses in the rush for diamonds?

Zimbabwe Diamond Production

The list of hardships and suffering linked to Zimbabwe’s diamond mines is growing longer by the day.

Since diamonds were discovered in the Marange fields in 2001, non-governmental organisations have been looking into abuse and dodgy dealings:

Human rights violations;
Opaque business deals;
Unfair treatment of residents;
Diamond smuggling.


The Marange diamond fields are in Chiadzwa, Mutare District, in eastern Zimbabwe. Thousands of people have been displaced to make way for mining operations.

Chinese mining companies and the Harare government made big promises to the displaced people, and their hopes are fading, with people saying they were duped to move out of their ancestral lands.

When Zimbabwean villagers from Chiadzwa were relocated to Agricultural Rural Development Authority (Arda) Transau, a state-owned farm in Odzi, about 40km from Mutare, to pave way for diamond mining, they were promised better life by both the government and several Chinese mining companies.

The government relocated more than 1 200 villagers from Chiadzwa to Arda Transau in 2009 after forcibly removing, in a bloody crackdown, more than 20 000 small-scale miners who had invaded the once-rich diamond fields in 2006.

Promises, promises

Arable lands, a US$5 000 compensation fee, grazing lands, schools and jobs are some of what the relocated residents were promised.

Chinese mining companies that were among the seven companies given mining rights include Jinan and Anjin — a company jointly owned by Chinese company Anhui Foreign Economic Construction Company Limited and Matt Bronze, a company owned by the Zimbabwe Defence Forces.

When the government under Zimbabwe’s long-time ruler, the late Robert Mugabe, took over the diamond fields through the newly formed Zimbabwe Consolidated Diamond Company (ZCDC) in 2016, some of the relocated villagers were hopeful that the move would improve their livelihoods.

Anjin was against Mugabe’s move and took his government to court.

In 2019, Anjin joined mining companies ZCDC in Chiadzwa after it was given back its mining license following pressure from Beijing on President Emmerson Mnangagwa, who came to power after Mugabe was toppled through a military coup in November 2017.

Hopes fading away

Many relocated residents say they got an unfair deal. They are living in dilapidated houses while their children are learning in makeshift classes. This is no clean water and few jobs.

“When I relocated to this area in 2010, this house was already cracking,” Jason Musiyanga (40), a father of three, said.

Musiyanga, whose name has been changed to protect his identity for fear of reprisal, says no one is coming to his rescue.

“I am living in fear. One day, this four-roomed house might just fall while I am asleep with my family,” he said.

Not enough to go around

Nomore Mamombe 51 said his one-hectare piece of land was not enough to accommodate his family of seven children with four of them married.

“Back in Chiadzwa, I had a 16-hectare piece of land which was enough for my children to build their own houses when they get married. Now we are sharing this four-roomed house,”  Mamombe said.

“It is against my Shona culture for me to share the same house with my daughters-in-law.”

Looking for answers

Neither the government nor the companies are claiming responsibility for the hardships of the residents of Arda Transau.

Each group of villagers was relocated by each of the seven companies that had been granted mining licenses by the government.

Musiyanga was relocated by Anjin, while Mamombe was relocated by Jinan.

Mines minister Winston Chitando did not respond to questions sent to him by The Africa Report.

Anjin secretary Richard Mahoya, in a telephone interview, requested the questions to be sent to him via email.

They were sent, and he acknowledged receipt, but he had not yet responded by the time of publishing.

No property security

“The Chinese built nearly 1 000 houses for over 1 200 households,” according to the Arda Transau Relocation Development Trust (ATRDT).

Tawanda Mufute, the ATRDT secretary, said they did not have title deeds to their properties.

“We have made strides for us to get title deeds but our efforts were fruitless. There are fears that if another mineral like gold is found where we are now, we might be relocated again. We do not have any property security,” he said.

Mufute added that the population had since grown and villagers were now competing for the few available resources.

“Our population is now more than 9 000,” he said.

A single school

The relocated villagers are sharing one school which was constructed by Anjin.

“Our primary school has a population of more than 1 200 pupils. This is against four blocks that were built by Anjin. Parents have also built another block, but they are inadequate. Some pupils are learning in makeshifts classes,” Mufute said.

He added that the relocated villagers were yet to be compensated by the Chinese companies.

“In terms of compensation, the families are yet to receive the US$5 000 compensation fee which they were promised. They were only given US$1 000 as a disturbance allowance when they were relocated,” Mufute said.

No clear lines of responsibility

Mufute said it was not clearly outlined who should be responsible for these relocated Chiadzwa villagers between the government and Anjin.

“It is all about blame games. The government is saying it is the Chinese companies yet the Chinese companies are saying they are waiting to hear from the government,” said Mufute.

Pleasing investors at the expense of the indigenous people’

Simiso Mlevu, spokesperson for Centre for Natural Resource Governance, said it was the responsibility of government to take care of the socio-economic needs of the people.

“The predicament of the people of Arda Transau simply shows that the government does not have people-centric policies,” she said.

“Our policies are aimed at pleasing the investors at the expense of indigenous people. Indigenous communities need to enjoy economic, cultural and social security in their own country.”

Shamiso Mtisi, the Zimbabwe Environmental Law Association’s deputy director, said it was important for government to comply with constitutional provisions related to evictions of communities.

“Government and companies must provide people with adequate information on displacement implementation plans including associated costs, compensation levels, where people will go, what they will get including time frames,” he explains.

Alrosa Raises Rough Prices Again

Alrosa Rough Diamonds

Alrosa has increased prices for the third consecutive contract sale, fueling concerns about unsustainable growth and tight manufacturing profits.

The adjustments were 4% to 5% on average, with a focus on 1-carat rough and larger, insiders told Rapaport News this week. Prices of that category are now higher than pre-pandemic levels, a customer noted.

Alrosa declined to comment on its “commercial strategy,” but a spokesperson said the Russian miner “assures that prices for its goods follow the real, confirmed demand from the midstream sector.”

The sale, which took place this week, came amid strong rough demand following positive holiday seasons in the US and China. But there were warnings of a slowdown as the quiet season approaches.

“Since the rough market is so strong, everyone accepts the [prices], but it’s becoming a bubble that might explode,” a source cautioned.

Industry members highlighted possible challenges for manufacturers. Rough prices have outpaced polished, they claimed, with the upcoming slow months raising concerns about end demand.

“[The miners have] taken away all the profit margin from the manufacturing pipeline, because…when the polished is ready, the polished market will be slightly weaker than today,” an Alrosa customer explained. “Probably, we will all lose some money, and not even make the costs.”

Alrosa maintained its policy of allowing customers to refuse any unwanted goods — a concession that has been in place since the start of the pandemic.

However, some clients felt compelled to buy to ensure they retain their allocations in the new contract period, which begins April 1, one customer pointed out. Even so, rough sales at the trading session will likely be lower than the $421 million it reported for January and the $361 million it garnered in February, reflecting a drop in the miner’s supply, he added.

De Beers: Less availability

De Beers will also offer limited supply at its sight next week as its reduced production plan for 2021 has affected availability. Sources expect sales of around $400 million, compared with $663 million in January and $550 million in February. The company lowered its full-year production forecast in January because of operational issues at some of its mines.

“We continue to take a prudent approach with our mine plans given the ongoing pandemic and associated uncertainty,” a De Beers spokesperson said Wednesday.

With fewer goods on the table, further price increases by De Beers are unlikely at next week’s sale, a sightholder predicted. The miner already increased prices in December, January and February, reversing a sharp price cut it implemented in August.

“There was a major pushback on the goods last month,” the sightholder commented. “In anything that [produces] pointers and large [polished goods], they went way too far, and everybody said so. There were also refusals. If [prices] go up now, everyone will just leave the goods.”

A Nearly 64 Carat Diamond Cartier Bracelet Could Fetch HK$40 Million at Sotheby’s

Cartier diamond bracelet

An iconic Cartier bracelet with 63.66 carats of pear-shaped D color, internally flawless diamond set on rock crystal is expected to fetch between HK$40 million and HK$65 million (US$5.16 million and US$8.39 million) at Sotheby’s Hong Kong’s sale of magnificent jewels in April.

Taking nearly 2,000 hours to create, the bangle-bracelet from the collection “L’Odyssée de Cartier —Parcours d’un Style,” pays homage to an Art Deco inspiration featuring sparkling stones and the French maison’s emblematic panther, orchid, and Oriental motifs.

Louis Cartier, the brand’s third-generation jeweler was a pioneer in working with rock crystal, which became popular in the 1920s. Cartier utilized a polishing technique from the Renaissance period to give a soft shine to rock crystal which, when paired with a diamond, creates an intriguing light effect.

The unique piece “combines a phenomenal diamond, mesmerizing design and impeccable craftsmanship, and represents a high jewelry collectible that will shine through time,” Wenhao Yu, deputy chairman of jewelry at Sotheby’s Asia, said in a statement.

Also on offer is “Circle of Happiness,” a bangle made of 277.7 carats of green jadeite-jade from Myanmar. Sotheby’s did not disclose the estimate of this bracelet.

Sotheby’s sale of magnificent jewels will also feature pieces from the houses of Boucheron, Bulgari, Chanel, Chopard, Graff, Harry Winston, Hermès, Van Cleef & Arpels, and more.

“The appetite for high-quality jewels has never been stronger in Asia, with discerning collectors looking for rare diamonds and gemstones, as well as unique and iconic designs,” Yu said.

Two Major Trade Bodies Sign Partnership Deal

rough diamonds

The World Diamond Council (WDC) and the Responsible Jewellery Council (RJC) have agreed to work together on key issues such as the Kimberley Process (KP), conflict diamonds and sustainability.

The two organizations have entered into a cross-membership partnership, meaning the RJC has become a member of the WDC, and the WDC has become a member of the RJC, they said Tuesday. The groups have also signed mutual codes of conduct.

An RJC official will join the WDC’s Kimberley Process (KP) Task Force and participate in discussions about matters including the expansion of the KP’s definition of conflict diamonds, principles for responsible diamond sourcing, and the worldwide adoption of the WDC’s System of Warranties. Meanwhile, a WDC official will become part of an RJC task force that focuses on ensuring the jewelry and watch industry achieves the United Nations’ Sustainable Development Goals (SDGs). Both appointments will take effect immediately.

The WDC and the RJC will report to their members on progress with the System of Warranties and the SDGs, and will help people in the industry apply them into their own businesses.

“Cooperation at this level is critical to raising the level of knowledge about responsible sourcing, driving action, and having a positive impact on all businesses, small and large, at every level of the diamond supply chain,” said Elodie Daguzan, the WDC’s executive director. “Through this partnership, we can do more to increase understanding of the [Kimberley Process Certification Scheme] and present a united industry front dedicated to broadening its scope through the expansion of the definition of conflict diamonds.”

US Sanctions on Myanmar Receive Broad Support

The,Burmese,Gems,Trader,Is,Offering,The,Variety,Of,Gem

Members of the jewelry industry are confident that US sanctions on Burmese gems will punish leaders of the Asian country’s military coup without damaging the trade.

The Myanmar army seized control of the country on February 1. On February 11, US President Joe Biden’s administration banned US companies from transacting with three entities that, it claimed, were associated with the perpetrators of the takeover: Myanmar Ruby Enterprise, Myanmar Imperial Jade Co., and Cancri (Gems and Jewellery) Co.

Crucially, the US did not blacklist all gemstones coming out of Myanmar (also known as Burma) — the most important of which are rubies and jade. This contrasts with the old sanctions regime, the Tom Lantos Block Burmese JADE (Junta’s Anti-Democratic Efforts) Act, which lasted from 2008 until 2016 but attracted criticism for harming the wrong people.

“[Those] sanctions really didn’t affect the generals at all, but they definitely affected the traders, the small business people,” said Jeffrey Bilgore, a gemstone dealer and former president of the American Gem Trade Association (AGTA). He expressed hope that the targeted nature of the new actions would have more effect.

“These sanctions are intended, first, to hurt the military leaders and to restrict their activity, and to prevent US businesses from doing business with them,” added Sara Yood, senior counsel at the Jewelers Vigilance Committee (JVC).

The State Department has told the JVC that it had no interest in a blanket ban on gemstone imports from Myanmar, “because they know that it hurts the small artisanal miners, which just hurts the actual people of Myanmar,” Yood revealed.

The JVC, like other trade groups, has published guidance for industry members, urging them to check the origin of their gems and cease doing business with any of the banned companies.

US companies should ask suppliers for written assurances that the colored gemstones they are buying from them do not originate from any of the sanctioned entities, Jewelers of America (JA) instructed. But the restrictions shouldn’t heavily impact the supply chain, said JA CEO David Bonaparte.

“I don’t think you’re going to see the dealers saying [they] can’t get ruby anymore from Myanmar,” Bonaparte pointed out. “Other legitimate companies are still able to do business, and there are legitimate companies that are not sanctioned.”

Still, there is some confusion over how much of the Myanmar gem industry is under the control of those three companies.

“I’m hearing [from the State Department] that [these businesses are] pretty significant,” Yood said. “From American gem dealers, I’m hearing that they’ve never heard of these companies. That doesn’t necessarily mean that they’re not significant. It may just be that by the time it gets to the US, it’s gone through 12 different hands.”

The vast majority of Myanmar’s jade goes to China, where the gem is highly popular. The more significant product for the US market is ruby.

Some rubies, especially lower-value ones, go through long and complex supply chains. This could lead to a greater bureaucratic burden for buyers and dealers.

“I would expect that if you are maybe not a US business, but you’re an intermediary type of gemstone dealer located outside the US, you can expect that your US customers are going to be asking for documentation that these gemstones have not come from one of these three companies,” said Yood at the JVC.
