Graff Unveils World’s Largest Square Emerald Cut Diamond At 302.37 Carats

Graff Lesedi La Rona Largest Square Emerlad Cut Diamond Model

Luxury jeweler, Graff, has unveiled its latest, and perhaps its greatest, big diamond creation, the “Graff Lesedi La Rona,” a 302.37-carat D-color, high-clarity stone that is being lauded as the world’s largest square emerald cut diamond. The London-based company also says it is the “largest highest clarity, highest color diamond ever graded by the Gemological Institute of America (GIA).”

Laurence Graff, the prestigious diamond dealer and founder of the eponymous international luxury jewelry brand known for its gem-centric high jewels, who has cut and polished the majority of the 20 largest diamonds discovered this century seemed humbled by his latest creation.

“My love affair with diamonds is life-long and crafting the Graff Lesedi La Rona has been an honor. This diamond, our diamond, is beyond words,” he said. “All our expertise, skill and accomplishment went into crafting this incredible diamond masterpiece, which is extraordinary in every way. The Graff Lesedi La Rona is an exceptional diamond with an exceptional cut and exceptional proportions, earning its place in history as the largest and finest of its kind in the world.”

The gem’s D color grade (meaning colorless) is the highest end of the GIA color scale. It is rare for any diamond to achieve this, much less one of more than 300 carats. While Graff noted its high clarity, meaning that the diamond has few or no inclusions or blemishes, it did not reveal the GIA clarity grade.

It is the principal diamond cut and polished from the 1,109-carat Lesedi La Rona rough, which was purchased in 2017 by Laurence Graff. In addition to the main diamond, 66 “satellite” diamonds have been polished from the rough, ranging in size from under a carat to more than 26 carats. Each diamond is inscribed with “Graff, Lesedi La Rona” and its unique GIA number, and is accompanied with a certificate of authenticity from Graff and the GIA. Graff began alerting its clients in November 2018 that they can purchase jewels with stones from the rough gem.

The 1,109-carat rough diamond, about the size of a tennis ball, has had a brief but storied existence. It was discovered by Lucara Diamond Corp., a Canadian diamond mining company, in November 2015, at its Karowe mine in Botswana. It is the largest gem-quality diamond discovered in more than 100 years and the second-largest in history. Its size is exceeded only by the legendary 3,016.75-carat Cullinan Diamond, mined in South Africa in 1905, which produced nine major diamonds that are part of the British Crown Jewels.

“There is a huge amount of good fortune involved in unearthing a rough diamond of this extraordinary beauty and importance,” Laurence Graff said. “We had an immense duty to cut the very, very best diamond imaginable from this rough.”

The gem was given the name, Lesedi La Rona, which means “our light” in Botswana’s Tswana language.

Lucara Diamond Corp. originally tried to sell the Lesedi La Rona in a standalone public auction at Sotheby’s London on June, 2016. It was an unusual way to sell a rough diamond. Normally, rough diamonds are sold privately to diamond dealers who then cut and polished it into a finished gem. It created controversy among these dealers. One of those who criticized the sale was Laurence Graff. It had an estimate of more than $70 million. However, it failed to meet its reserve price as bidding stalled at $61 million.

The Graff gemologists and master polishers spent 18 months analyzing, cutting and polishing the stone in order to reveal the 302.37-carat Graff Lesedi La Rona Donald Woodrow

In September 2017, Graff Diamonds announced that it had purchased the diamond for $53 million in a handshake deal between Graff and William Lamb, former president and CEO of Lucara. Once purchased, the diamond was moved to South Africa where Graff’s cutting and polishing processes are carried out.

Laurence Graff said he was confident the Lesedi La Rona would result in “sensational polished gems.” In May 2016, he purchased a 373-carat rough diamond that was believed to have come from the same rough stone. His experience with this gem gave him enough confidence to think he could predict what the Lesedi La Rona might produce.

Even with this experience the Lesedi La Rona presented a unique challenge for Graff’s gemologists. They had never analyzed a stone this large. In fact it was so large that it couldn’t be viewed with existing equipment. A scanner had to be custom built specifically for the Lesedi La Rona with new imaging software capable of probing its immense interior.

With the new equipment, the gemologists were able to explore deep within the diamond and map out the maze of imperfections. They used this information to plot which cuts would yield the largest and highest clarity diamonds possible.

At first, the technical analysis of the Lesedi La Rona concluded that a 300-carat diamond wasn’t possible. However, Laurence Graff said he was convinced that this exceptionally rare weight could be achieved and challenged his staff to accomplish this.

After months of analysis, the plan for cutting and polishing the diamond was so precise there was no room for error. It took hundreds of hours just to polish the table facet, the largest facet at the top of the diamond.

By the time the final finessing of the diamond’s facets had taken place, more than 18 months had elapsed.

”Cutting a diamond of this size is an art form, the ultimate art of sculpture,” Laurence Graff said. “It is the riskiest form of art because you can never add and you can never cover up a mistake, you can only take away. You have to be careful and you have to be perfect.”

The GIA identified the Lesedi La Rona rough as part of an elite group of “super deep” diamonds formed three times deeper than most other diamonds. Rare emissaries of geological information, Graff donated fragments of the Lesedi La Rona to the Smithsonian Institute to help advance diamond research.

Firestone finds another massive diamond at Lesotho mine

Firestone 72 Carat Yellow Rough Diamond

African focused Firestone Diamonds has dug up a 72 carat yellow, whole makeable diamond at its Liqhobong Mine in Lesotho, the second one over 70 carat it has found this year.

The stone, recovered over the weekend together with a 22 carat makeable white stone, followed by an 11 carat fancy light-pink diamond found at the asset.

“Makeable” diamonds are those whose shape allows to cut one large diamond from it. In contrast, “sawable” stones can be cut in half in order to create two smaller diamonds.

“The stone, recovered over the weekend together with a 22 carat makeable white one, followed by an 11 carat fancy light pink diamond found at the asset.”

The two diamonds, found within the northern lower grade part of the pit, will go on sale at Firestone’s next tender, which is scheduled to take place during May 2019.

Shares in the company were 7.3% higher at 2.2p following the news.

Last month, a white 70 carat diamond from also from the Liqhobong mine was auctioned for an undisclosed price, following a 46 carat precious rock, also from the same mine, which was sold for $1 million in December.

Diamond prices have been under pressure and miners are struggling across the board, especially those producing cheaper and smaller stones where there is too much supply. In December, some of Rio Tinto’s customers refused to buy cheaper diamonds, while De Beers has been forced to cut prices and offer concessions to buyers.

Firestone spent $185 million building Liqhobong, which started production in late 2016, and boasts over 11 million carats in reserve. The total open pit resource contains over 17 million carats to a depth of 393 metres.

De Beers Closes Diamond-Reselling Unit

De Beers Diamond Solitaire Jewellery

De Beers is shutting its diamond-recycling division, as digital advancements in the sector have lessened the need for its services.

The International Institute of Diamond Valuation (IIDV) was set up in 2016 to repurchase and recycle diamond jewelry that consumers no longer wanted. De Beers began the operation after noting the difficulty consumers faced in trying to sell their jewelry at a fair price. The venture provided a means of emphasizing the enduring value of diamonds, De Beers said.

However, since IIDV launched, technology in the industry has improved, and online consumer-to-consumer selling platforms have become a more popular option, the company explained.

“Following a number of years gaining experience in the diamond-recycling sector, we have taken the decision to suspend the activities of the International Institute of Diamond Valuation,” David Johnson, De Beers’ senior manager for media and commercial communications, told Rapaport News Thursday.

While the project is no longer a viable option, it has provided De Beers with valuable insight into consumer behavior and the needs of its retail partners, Johnson explained.

“We know that consumer acceptance of the consumer-to-consumer market is growing and likely to be the future of this sector, and we will therefore continue to look for opportunities in this space,” he added.

Why Canada’s diamond miners are in trouble

Canadian diamond mining

It’s only been 20 years since diamond mining began in Canada, but the industry is already on its knees.

The story of how two prospectors, down to their last nickels, discovered diamonds in Canada’s frozen north is the stuff of legend.

Back in 1982, Chuck Fipke and Stewart Blusson laid low in a pup tent by day while their competitor De Beers hauled 45-gallon drums of rock samples to a nearby outpost for transport to South Africa. Using the long hours of summer sunlight north of the 65th parallel, the two searched for indicator minerals — bits of garnet, chromite or zircon often found with diamonds — while their opponent slept. Nine years later their treasure hunt culminated with the discovery of a carrot-shaped funnel of blue-grey kimberlite rock that would become Ekati — the first great diamond mine outside Southern Africa or Russia.

For all the drama associated with the discovery in Canada’s Northwest Territories — hacking through snow and ice taller than the average person, battling Arctic winds and temperatures of -50 degrees Celsius — what came next is proof that diamond mining in Canada is not for the faint of heart.

Whether a diamond mine makes money or not comes down to three variables: production costs, the grade and size of the deposit, and the price the diamonds fetch on global markets. In recent years, all of these have conspired to bring the Canadian industry to its knees.

“It’s disconcerting, given the way it started,” said Blusson, an active octogenarian who helms diamond exploration company Archon Minerals Ltd. and still flies his own helicopter. “Twenty years is only all we’ve been mining now. Is there going to be another 20 years? I don’t know.”

Ekati and sister mine Diavik, located 210 kilometres (130 miles) south of the Arctic Circle, are now old, tired and running out of diamonds; they will likely both close soon. So far, the mines that were designed to replace them aren’t faring well either.

De Beers, the London-based diamond giant, has already flooded one of its huge Canadian mines; the other, Gahcho Kue, took 21 years to reach production and is now turning out stones worth far less than it hoped. It’s a similar story for a scattering of newer mines that have sprung up across the country: low quality stones, management mistakes and falling prices for their stones put a terrible squeeze on their businesses.

Every operating mine in Canada produces stones that fall below the global average, with all but one mine producing diamonds that fetch less than US$100 a carat. By contrast, both De Beers and Alrosa, which mine more than half the world’s diamonds, average more than US$160 a carat. For smaller miners in Southern Africa, the gap is even more extreme. Gem Diamonds Ltd. and Lucara Diamond Corp. had average selling prices of US$2,131 and US$502 per carat respectively last year.

While Canada is now the world’s third-biggest diamond producer, behind Russia and Botwsana, its average selling price is the cheapest of the major diamond mining countries.

The question for Canadian producers is whether it makes sense to change strategy and focus on bigger, more valuable stones.

“Can you save considerable amounts of money by upping your cut-off size and just recovering those goods?” asks Eira Thomas, who co-founded Stornoway Diamond Corp., and served as its president and chairwoman for years. Now chief executive officer of Vancouver-based Lucara Diamond, which produces high-end diamonds in Botswana, Thomas is more optimistic about Canadian production than Blusson.

“They’re not in jeopardy of failing, they’re just not making as much money as we had hoped,” Thomas said. “And that, of course, is translating to discontented shareholders more than anything else.”

Shares Plunge

That may be an understatement. Shares of Longueuil, Quebec-based Stornoway trade near a record low of just 10 US cents a piece, even after opening the US$750 million Renard mine in 2017, the province’s first. It’s a similar story for Toronto-based Mountain Province Diamonds Inc., which owns Gahcho Kue with De Beers. Its shares are close to the lowest since the financial crisis, cutting its market value to below $250 million (US$187 million).

Canada’s flagship miner, Dominion Diamond Mines, the owner of Ekati and a stake in Diavik with Rio Tinto Group, has also had a rough ride. After being bought for US$1.2 billion more than a year ago, the company has been hit by an exodus of top management, with at least five executives leaving, including its CEO and CFO.

The new owner, billionaire Dennis Washington, has also sought to sell the company, according to people familiar with the situation. Washington denied this is the case. Dominion is currently studying two potential expansions, though both projects produce even lower-quality stones, making them a tough sell in the current environment.
Maturing Sector

“You have a maturing sector in Canada: Ekati and Diavik were good mines. When you have good mines, others follow even if the economics are a bit more of a close call,” said Anish Aggarwal, a partner at consultant Gemdax, based in the diamond trading city of Antwerp. “That’s becoming a problem in many mining jurisdictions, not just Canada.”

There are other problems facing the sector. Indian Prime Minister Narendra Modi’s fight in 2016 against so-called black money caused producers such as De Beers to hold back supply, which has now been sold back into the market. A weaker rupee is also making diamonds more expensive for Indian manufacturers, who cut or polish about 90 per cent of the world’s stones.

There is also increasing pressure from synthetic diamonds. While still a very small part of the industry, the potential threat they pose risks further hurting sentiment in an already fragile market.

Still, there are reasons why Canadian diamond mines keep getting built — and in some cases it has little to do with economics. For De Beers, which has developed three mines there, Canada reduces its dependence on Botswana, where most of its diamonds are mined.

Aggarwal, who was involved in developing what became known as the “CanadaMark” brand to capitalize on the country’s clean image, says there’s potential for more to be done with that.
Canada Brand

“Consumers in the U.S. and Canada have positive associations with Canadian diamonds,” he said. “There’s an opportunity with origin. It’s a tool that the miners can use to enhance the value of their diamonds.”

But the track record there hasn’t been good either. Canada tried to create a polishing industry in the Northwest Territories, capitalizing on the backlash against “conflict” diamonds. “Made in Canada” diamonds seemed an easy sell: ethically produced, mined from ice, cut, polished, and laser-etched with a tiny polar bear. Today, the polishing industry is all but gone and attempts by Dominion to revive the CanadaMark have met with mixed success.

There’s no getting around the higher costs of operating in Canada’s frozen tundra. Everything — labour, fuel and construction — costs more in the remote north.

“You look at these diamond mines, you’ve got your own road, your own airstrip, your own power grids,” said Tom Hoefer, executive director of the NWT & Nunavut Chamber of Mines. “That may be okay if you’ve got a world class deposit, but not everybody is mining world class assets.”

FTC sends warning letters to companies regarding diamond ad disclosures

Federal Trade Commission

FTC staff sent eight letters to jewelry marketers warning them that some of their online advertisements of jewelry made with simulated or laboratory-created diamonds may deceive consumers, in violation of the FTC Act.

The letters note that in July 2018, the FTC issued updated Guides for the Jewelry, Precious Metals, and Pewter Industries that provide marketers with information on how to make non-deceptive representations about jewelry and related products, including mined, lab-created, and simulated diamonds.

Failure to follow the Guides, the staff warns, may result in enforcement actions if the FTC determines the companies engaged in unfair or deceptive acts or practices. Such actions could result in civil penalties if the company engaged in practices knowing that the Commission has already deemed them deceptive in earlier litigation.

In the letters, the staff expresses concerns that some of the companies advertising fails to conform to the current version of the Guides, and may therefore deceive consumers. Specifically, the staff points out examples where the advertising might imply that a simulated diamond is a lab-created or mined diamond, or that a lab-created diamond is a mined diamond, or where required disclosures about the source of the diamonds are not proximate to the individual product descriptions.

To help educate the companies, the letters caution them not to use the name of any precious stone, including diamonds, to describe a simulated or lab-created stone, unless the name is immediately proceeded by a clear and conspicuous disclosure that the product is not a mined stone. The staff also encourages companies selling simulated diamonds to avoid describing their products in a way that may falsely imply that they have the same optical, physical, and chemical properties of mined diamonds.

The letters also note that similar non-deceptive disclosures are required when advertising jewelry containing precious stones other than diamonds, including emeralds and rubies, as well as pearls.

Several letters also note that the companies have advertised their jewelry as Eco-friendly,Eco-conscious,or sustainable, and that such terms can be interpreted to imply certain specific environmental benefits. Sellers must have a reasonable basis for making such claims for any products and the claims should be adequately qualified to avoid deception. The letters admonish the companies not to use unqualified claims such as Eco-friendly,Eco-conscious,or sustainable, as it is highly unlikely that they can substantiate all reasonable interpretations of these claims.

Finally, in each letter, the staff asks the companies to advise them within 10 days within receipt of steps they plan to take to revise their marketing so that it follows the Jewelry Guides and therefore complies with the FTC Act.

88 Carat Flawless Diamond Fetches $13.7 Million USD

88.22 Carat Oval Diamond

A flawless 88.22 carat diamond fetched more than $13.7 million at the Hong Kong Sale of Magnificent Jewels and Jadeite held Tuesday.

The total, which includes commissions and fees, surpassed the high estimate of $12.7 million. The D color, type Ila, oval brilliant diamond was the top lot in the sale of 2oo items.

A Japanese private collector purchased the stone and named it the “Manami Star,” after his eldest daughter.

“We were thrilled to handle a diamond of such rarity, which now takes its place in the roster of top white diamonds to have come to the market here at Sotheby’s Asia,” said Patti Wong, Sotheby’s chairman in Asia.

GIA Aligns Lab-Grown Reports with FTC Standards

GIA lab grown grading report

The Gemological Institute of America (GIA) has updated the language in its lab-grown-diamond certificates to conform to the recent Federal Trade Commission (FTC) guidelines.

The grading lab will no longer use the term synthetic when referring to diamonds created in a lab, either inside its reports, or in the title, it said Friday. The GIA will continue to use descriptive terms of color and clarity for lab-grown diamonds, indicating the range of grading they refer to on a scale in the report.

Additionally, the certificate will include a QR code which will link to the GIA’s report-check service, and provide consumers with more information about the growth process of lab-grown diamonds. It will also list any detected clarity treatments the stone has undergone.

The GIA will include a comment on the report disclosing the fact that the stone is man-made and has been produced using either chemical vapor deposition (CVD) or High-Pressure, High-Temperature (HPHT).

“Over the past few years, there has been an incredible advancement in the technology by which laboratory-grown diamonds are made,” said GIA CEO Susan Jacques. “With the increased availability of man-made diamonds in commercial qualities, sizes and quantities, and with greater consumer awareness of and desire for this product, GIA is making these changes to align with the revised FTC guides and changes in the market.”

Earlier this month, HRD Antwerp announced changes to its lab-grown-diamond reports, including updating the language to match those of natural diamonds, and expanding its color categories for synthetic stones. It will also launch a lab-grown-diamond-jewelry report in September.

The new GIA lab-grown-diamond reports will be available from July 1. Customers that have purchased synthetic-diamond reports from the GIA prior to that date can exchange them for a new certificate at no cost, the GIA noted.

Correction: The GIA will not be adopting the same 4Cs descriptions that it uses for natural diamonds in its lab-grown diamond grading reports, as initially indicated in the above story. It will continue to use descriptions such as “near colorless” and “very slightly included” when describing the color and clarity of a lab-grown diamond.

Last kimberlite trucked to plant at De Beers Victor mine

De Beers last truck

The last truckload of kimberlite from Ontario’s first and only diamond mine has left the pit. De Beers Canada said mining ceased on March 5 – 11 years to the day after the official opening in 2008.

The honour of driving the last truck went to Nancy Wesley, of Kashechewan First Nation. She worked at Victor for 11 years, as a haul truck driver, dozer operator and production drill operator.

Stockpiled kimberlite will keep the recovery plant running until early May.

The Victor mine was forecast to produce 6 million carats of diamonds over its life, but it beat that by recovering a total of 8 million carats – with a record 936,000 carats produced in 2018.

The project provided about 1,360 jobs and $3.7 billion of revenue to the province.

Thieves tunnelled into jewellers to take £1,000,000 in diamonds and gems

Jewellery theft

An upmarket Fleet Street jewellers has been robbed by burglars who tunnelled in Hatton Garden style and made off with an estimated £1 million in diamonds and gems.

George Attenborough and Son Jewellers on Fleet Street in central London was hit at some stage over the weekend, as thousands of runners competing in the London Landmarks Half Marathon thundered past nearby. The firm advertises items worth tens of thousands of pounds such as Cartier diamond rings on its website.

The Sun suggested the thieves who are still at large used drills to gain access to the secure building and complete the raid. A Scotland Yard statement confirmed members of its Serious and Organised Crime Command were involved in the investigation.

It said: ‘Police were called shortly before 2am on Monday, March 25, to a report of a burglary at a jewellers in Fleet Street. ‘A quantity of jewellery was stolen. ‘An investigation has been launched, led by detectives from the Met’s Flying Squad.

‘Forensic examination work is continuing at the scene. ‘No arrests have been made. Enquiries are ongoing to establish the circumstances and identify those responsible.
