Petra finds 39-carat blue diamond at Cullinan mine

39.34 carat blue diamond recovered

South Africa’s Petra Diamonds has found yet another big rock at its iconic Cullinan mine, a 39.34 carat Type IIb gem said to be of “exceptional quality” due to both its colour and clarity.

The miner didn’t indicate the diamond’s potential value but said it would sell it in a special tender.

Cullinan is known as the world’s most important source of blue diamonds, as well as being the birthplace of the 3,106-carat Cullinan diamond, which was cut to form the 530-carat Great Star of Africa.

The operation also yielded the 317-carat Second Star of Africa. They are the two largest diamonds in the British Crown Jewels.

Flawless largest purple-pink diamond expected to fetch over $25 mn at Hong Kong auction

15.81 carat fancy vivid purple pink diamond

A 15.81 carat Sakura diamond, the largest of its kind to ever appear for sale, will go under the hammer at Christie’s upcoming Hong Kong Magnificent Jewels Live Auction on May 23, the auction house announced on Tuesday. Estimated at $25 million to $38 million, the “fancy vivid purple pink internally flawless” diamond will be the star highlight of the sale.

It is the diamond’s exceptional rarity, extraordinary optical transparency, brilliant colour, and enormous size that make it an immensely important, and eternal masterpiece of nature.

As fewer than 10 per cent of pink diamonds weigh more than one-fifth of a carat, this fancy vivid purple-pink diamond is of an unprecedented size of 15.81 carats, which is the largest of its kind Fancy Vivid Purple Pink to be offered at any auction.

It added that the lot fell in the exclusive group of the four per cent of pink diamonds that possess a colour deep enough to qualify as “fancy vivid”.

This magnificent gem is graded ‘fancy vivid’ for its perfect display of strong saturation and remarkable pink hue with a secondary colour of purple, resembling the fascinating colour of cherry blossoms – appropriately coinciding with spring.

Three +100 carat diamonds recovered at Lucapa’s Lulo mine

Lucapa rough diamonds

Lucapa Diamond Company and its partners Endiama and Rosas & Petalas have announced the recovery of three +100 carat diamonds by Sociedade Mineira Do Lulo from the Lulo alluvial diamond mine in Angola.

The 131-carat is a Type IIa D-colour diamond, the 118-carat is a brown diamond and the 133-carat stone is a lower-quality grey diamond.

Six +100 carat diamonds have been recovered from Mining Block 46 (MB46) in the last three months, reaffirming its recent elevation to the Lulo mining block with the best +100 carat diamond occurrence rate – one +100 carat diamond for every ~20,000 bcm’s of gravel.

The Canguige catchment and adjacent priority kimberlites are already the focus of the Project Lulo JV kimberlite exploration program, and the frequent recovery of large high-value diamonds underpins the prospectivity of this area.

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 Gets Colorful with New York Auction

The three Perfect Palette diamonds

Three rings featuring diamonds with fancy-vivid color will head up the Christie’s Magnificent Jewels auction in New York next month.

The trio of jewels, called the Perfect Palette, comprises a 2.13-carat, fancy-vivid-blue diamond ring, estimated at $2 million to $3 million, Christie’s said Tuesday. Also included are a 2.34-carat, fancy-vivid-orange diamond ring and a 2.17-carat, fancy-vivid-purplish-pink diamond ring, both with a high valuation of $2.5 million. Each will be offered as a separate lot at the April 13 sale, the auction house added.

Other notable items are two oval modified brilliant-cut diamonds. The first — a 25.55-carat, fancy-vivid-yellow, VS1-clarity diamond ring — has a high estimate of $1.2 million, while the 6.56-carat, fancy-intense-orangey-pink, VVS1-clarity diamond ring carries an upper valuation of $1 million.

An oval mixed-cut, 3.02-carat, fancy-vivid-purplish-pink, SI2-clarity diamond ring, set with round pink diamonds on the band, is estimated at up to $1.5 million. Christie’s will offer that piece without reserve.

Meanwhile, a pear brilliant-cut, 38.04-carat, D-flawless, type IIa diamond ring with a high estimate of $3.5 million will feature as a top lot. An emerald-cut, 14.50-carat, D-color, internally flawless, type IIa diamond valued at up to $1 million is also up for sale, as are signed pieces by designers Suzanne Belperron, Bulgari, Cartier, David Webb, Harry Winston, Van Cleef & Arpels, and Verdura.

Christie’s will hold a concurrent Online Jewels auction from April 8 to 20, featuring a selection of items from Bulgari, Cartier and Elsa Peretti for Tiffany & Co., among others. The auction house has not decided whether it will hold an in-person sale or conduct live bidding over the phone and online, a spokesperson told Rapaport News.

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.

Graff Unveils New High-Jewelry Collection: Tribal

Graff's new Tribal high-jewelry collection features a stunning emerald suite

Graff is known for its exquisite diamonds. The London-based jewelry house has acquired many notable diamond acquisitions, some that set world records. As a vertically integrated jeweler, the house cuts, polishes, and sets these incredible diamonds in-house, allowing it to control every facet of these stunning diamonds.

The collection focuses on white and yellow diamonds, with one exceptional emerald suite, in three sculptural motifs.

For me, the iconic, timeless symbols that unite the collection evoke a deep feeling of being connected to the world around us on a universal level.

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.
