Belgium’s diamond trade slowed in June, with polished exports down 44% year on year to $469 million, according to data from the Antwerp World Diamond Centre (AWDC). However, the rate of decline eased following heavier drops in April and May, when the global industry shut due to the coronavirus. US orders rose 4% to $173 million in June, indicating a gradual recovery as the important retail market reopened.

About the data: Belgium is usually a net exporter of polished diamonds. As such, net polished exports — representing polished exports minus polished imports — will normally be a positive number. The nation is also a net exporter of rough. While Antwerp is home to some high-value manufacturing, its main role in the market is as a facilitator of rough-diamond trading, with companies from around the world coming to the city to buy rough. The net diamond account is total rough and polished exports minus total imports. It is Belgium’s diamond trade balance, and shows the added value the nation creates by exporting rough or manufacturing it into polished.

Two Fancy Colored Heart Shaped Diamonds

A fancy vivid pink Diamond and a fancy vivid blue diamond

Two hearts, one blue, the other pink, will appear at Sotheby’s Hong Kong Magnificent Jewels auction as if they were always meant to be together. They will be sold separately during the July 10 sale at the Hong Kong Convention & Exhibition Centre. Combined, their high estimate is $18.5 million.

The first is a 5.04 carat fancy vivid blue heart modified brilliant-cut diamond. The gem has a VS2 clarity grade, according to its lab report. The heart-shaped gem is mounted on a platinum ring flanked by two pear-shaped diamonds. Its estimate is between $7.7 million and $9.7 million.

Its would-be partner is a 4.49-carat heart modified brilliant-cut, internally flawless, fancy vivid pink diamond. It’s mounted on an 18k white gold ring flanked by pear-shaped diamonds. Its estimate is between $7.5 million and $8.8 million.

India Extends Import Curbs as Surat Shuts Again

Melee grading at De Beers Group

Indian trade bodies have recommended continued limits on rough-diamond imports in July, with a fresh weeklong shutdown of the Surat cutting sector adding to concerns about the market.

The Gem & Jewellery Export Promotion Council (GJEPC) and four other organizations have called for the industry to avoid shipping rough into the country between July 10 and 31. They are giving companies a window of July 1 to 9 in which to import goods to keep factories operational, and will review the policy in the final week of the month, the groups said in a letter to members Tuesday.

“Over [the] last few weeks, manufacturing operations have commenced, albeit under several constraints because of issues [such as social distancing],” they noted. “In view of this, it was generally felt that some new raw materials would be needed for continuing operations and keeping the labor force employed.”

Weak polished demand during the coronavirus pandemic led to fears of a diamond oversupply, prompting the GJEPC, the Bharat Diamond Bourse, the Mumbai Diamond Merchants Association, the Surat Diamond Bourse and the Surat Diamond Association to call for a rough-import pause for a month from May 15. They later delayed it to June 1 so companies could complete outstanding shipments.

These initial curbs have helped reduce stockpiles and manage cash flow, while miners have also offered support by being flexible with contract clients’ purchasing obligations, the groups added. The GJEPC will write to the large rough producers, urging them to continue that policy to avoid a collapse in the value of inventory, the letter stated.

However, the industry must still “proceed with great caution,” the organizations warned following a Saturday meeting with trade members.

“It is difficult to say when the Indian diamond industry will be fully operational,” said GJEPC chairman Colin Shah. “The industry [has] resumed manufacturing activities in a limited way, while maintaining all the stringent safety norms. But these are unprecedented times.”

The trade must, therefore, strike a delicate balance between continuing operations and maintaining workers’ livelihoods on the one hand, and ensuring health and safety on the other, Shah added.

Surat closure

The sector suffered a setback on Monday when the Surat Municipal Corporation ordered the closure of all diamond-manufacturing units in the city for seven days, according to a note the Surat Diamond Association released on Tuesday. More than 700 diamond workers in Surat have tested positive for Covid-19 in recent weeks, with the polishing industry becoming a local virus hot spot, the Deccan Herald reported.

Diamond cutting in India has struggled to restart, even after the government relaxed the lockdown rules it introduced in March to contain the coronavirus. The Surat sector gradually reopened in May following a full closure, with the government allowing 50% of workers in factories and 33% in offices. But several outbreaks at manufacturing units have forced companies to shut again and send workers into quarantine.

Local media have carried reports of staff members attending work while unwell, with communal meals and the use of air-conditioning intensifying the risk of infection.

China dispute

Adding to the troubles, a diplomatic rift with Beijing has led to unsold memo goods being held up at Indian customs on their return from Hong Kong and China, traders told Rapaport News. The Indian government has reportedly told customs officials to check all imports from China following a June 15 military clash in a disputed Himalayan border region that killed 20 Indian soldiers and caused an unknown number of Chinese casualties.

Companies might need to route goods via other locations such as Dubai at extra cost to avoid the bottleneck, an executive at a diamond manufacturer explained.

“We have been instructed [by customs agents] not to export anything, specifically diamonds, from Hong Kong to India, as customs have completely refused to release those parcels,” he said. “I see a problem escalating, and if this situation doesn’t get under control in the next two or three weeks, there definitely will be an issue.”

A 28 carat emerald shape type 2A diamond became the most expensive auctioned online

28.86 carat diamond ring

On Tuesday, Christie’s auctioned off the most expensive jewel ever sold on an online auction. The 28.86 carat diamond sold for $US2,115,000 million.
One of the rarest diamonds in the world, the Type 11a diamond is formed from pure carbon.

“The spectacular 28.86 carat D colour diamond received immediate attention upon its announcement,” Christie’s Head of Jewellery Rahul Kadakia said in a statement. “The stone possesses a transparency and purity which can only be found in the world’s finest diamonds.

The sale of this exceptional stone established the record for a jewel sold in an online only auction, demonstrating greater client confidence in Christie’s digital ability and online sale platform.”

The sale was the final day of Christie’s Jewels Online sale.

Buyers Snub De Beers and Alrosa over High Prices

Rough diamonds

De Beers and Alrosa continued to see rock-bottom sales in June as buyers rejected the miners’ high rough prices in favor of cheaper goods from smaller suppliers.

“[The major miners] want to hold on to prices, so people don’t see any [incentive] to buy because it’s difficult to sell and make money,” a sightholder told Rapaport News. “[Manufacturers and dealers] are already sitting on large inventories of polished and rough.”

The two largest producers have maintained their prices at pre-coronavirus levels, while other miners holding tenders in Antwerp have sold at prices 15% to 25% lower than in February, an Alrosa client observed. Even the smaller producers’ prices were inflated, he explained, as they were serving customers seeking specific items in small quantities.

If De Beers or Alrosa were to put their monthly allocations on the open market, they would fetch prices up to 30% below their current levels, the dealer estimated. “There is no appetite for rough, as factories [in India] have been operating on a very, very small capacity for a month,” he stressed.

“Sales of polished have not improved dramatically, and stocks are still there,” a sightholder added. “Factories have no reason to open, so why would we buy rough?”

De Beers held its June sight last week, with limited viewings in Antwerp instead of at the usual location in Gaborone, Botswana, due to Covid-19 travel restrictions. The sight had an estimated value of around $40 million, according to a source with knowledge of the sale. De Beers hasn’t released sales data since its February sight, and is scheduled to publish its earnings for the first half of the year on July 30.

Alrosa also struggled to attract buyers to its latest trading session, which ended June 15, after reporting record low revenues in April and May. The Russian miner is due to publish its June data on July 10.

Kick-starting sales

Rough buyers have sensed an increased urgency for both De Beers and Alrosa to increase revenue, after the miners allowed 100% deferrals of purchase allocations during the coronavirus crisis. They introduced that flexibility to protect prices and avoid flooding the market with goods, but now customers are unwilling to resume buying unless value improves. Five Alrosa clients have already given up their statuses as Alrosa contract customers since March, perceiving pressure to make purchases.

To drum up interest, Alrosa is considering holding contract sales outside Moscow for its July session, with Antwerp the likely venue, and is weighing up whether to continue its deferrals policy.

“Being committed to the prudent sales policy, in subsequent trading sessions of the year we will use all available instruments to maintain supply-and-demand balance and help to normalize cutters’ level of inventories,” an Alrosa spokesperson said. De Beers declined to comment.

Most manufacturers in India have enough rough to keep their factories going until August, and are only buying if they have specific shortages, dealers explained. That has boosted sales at smaller miners that are in need of liquidity and have sold low volumes at reduced prices to cutters looking to fill limited inventory gaps.

The recent increase in Covid-19 cases in Surat has added to the predicament, dealers asserted. The Indian polishing industry hasn’t returned to consistent operations since the government allowed it to reopen last month, with several companies forced into temporary shutdowns following virus outbreaks.

“Most [Alrosa] clients have the same attitude as me — they don’t need the goods, and they’re not ready even to look at the goods at this price,” a dealer said.

Gradual release

However, deep and sudden discounts on rough could damage the entire market, sightholders acknowledged. As such, they only foresee De Beers and Alrosa reducing prices when the market recovers, which the buyers expect to happen in the fall, assuming retail stores and trading centers continue to reopen. Only then will the largest miners gradually release their stockpiles, dealers predicted.

“Let [the goods] come in very small quantities, so in the meantime overall inventory will slowly decline, the industry will generate money, and banks will feel comfortable,” a dealer argued. “We will start our business from September onward, when the Christmas season begins.”

Indeed, buyers will have to return to De Beers and Alrosa if they need more significant volumes when the market improves.

“Maybe by then we will have more of a balance of supply and demand, and maybe we’ll have more confidence to buy at certain prices that we don’t have now,” a sightholder said.

GIA to Reopen New York Lab

The GIA’s New York laboratory

The Gemological Institute of America (GIA) is reopening its New York grading laboratory Monday following a three-month shutdown due to the coronavirus.

“As restrictions are lifted and the global gem and jewelry industry begins to recover, we are safely reopening GIA locations, returning staff to work and preparing to engage in our mission-driven activities,” GIA CEO Susan Jacques said Thursday. “We are strictly following government regulations and guidelines, implementing new processes, and adapting our facilities to keep everyone who comes to GIA — staff, clients, students and visitors — healthy and safe.”

With the 47th Street venue back in action, all 11 of the GIA’s laboratories will have unlocked their doors. The 10 other sites are steadily increasing their hours and adding extra shifts to meet growing demand for their services, the GIA said.

Meanwhile, its gemological schools in Taipei and Hong Kong are open, and all other GIA educational centers will welcome back on-campus students “in the near future,” it said.

The organization closed most of its sites in March as the virus spread, and gradually reopened them as lockdown restrictions eased. It will continue to monitor local-government and health rules in each location and adjust its services as necessary.

Origin of British Crown Jewels’ diamond revealed

Queen Elizabeth the II British Crown Jewels

The famous Cullinan diamond, which is now the centrepiece of the British Crown Jewels, likely originated in Earth’s lower mantle, right beneath the rigid and stable continental plates, where the mantle is slowly moving or convecting.

The finding is part of ongoing research carried out by Evan Smith and Wuyi Wang at the Gemological Institute of America. The new insight was presented by Smith at the virtual 2020 Goldschmidt Conference organized by US-based Geochemical Society and the European Association of Geochemistry.

Smith and his team concluded that the Cullinan diamond was likely formed in the lower mantle and can be considered a ‘super-deep’ stone after examining an analog, large 124-carat diamond from Gem Diamonds’ (LON: GEMD) Letšeng mine in Lesotho.

According to the researchers, recent analyses of this walnut-sized diamond revealed that it contains remains of an important element: bridgmanite.

The Cullinan II or the Second Star of Africa, a diamond that weighs 317.4 carats, is mounted in the Imperial State Crown. 

“Finding these remnants of the elusive mineral bridgmanite is significant. It’s very common in the deep Earth, at the extreme pressure conditions of the lower mantle, below a depth of 660 kilometres, even deeper than most super-deep diamonds,” Smith said in his presentation. “Bridgmanite doesn’t exist in the upper mantle, or at the surface. What we actually see in the diamonds when they reach the surface is not bridgmanite, but the minerals left when it breaks down as the pressure decreases. Finding these minerals trapped in a diamond means that the diamond itself must have crystallized at a depth where bridgmanite exists, very deep within the Earth.”

By aiming a laser at the tiny inclusions trapped inside the diamond, the researchers found that the way the light scattered (using a Raman spectrometer) was characteristic of bridgmanite breakdown products.

The Letšeng mine diamond is so pure that it doesn’t contain nitrogen in its crystal structure. This characteristic classifies it as a ‘Clippir’ diamond, which is the same category as that of the Cullinan diamond.

“What is special about this one is that it is the first Clippir diamond for which we can firmly assign a lower mantle origin, that is, below 660 kilometres,” Smith said. “Previously, we had known that Clippir diamonds are super-deep and speculated that their depth of origin might span 360 to 750 kilometres depth, but we hadn’t actually seen any that were definitely from the deeper end of this window.”

In the researcher’s view, this finding gives a better idea of exactly where Clippir diamonds come from and also shows that there is some overlap in the birthplace for Clippir diamonds and type IIb diamonds, such as the famous Hope diamond. This rare blue gem was owned by monarchs, bankers, heiresses and thieves until it landed at the Smithsonian National Museum of Natural History in Washington DC.

The overlap that Smith refers to points to a previous study in which the researcher showed that the Hope and other IIb diamonds originate in Earth’s deep mantle and that the boron that gives them a blue hue comes from the bottom of the oceans. To get into the diamond, the element is first dragged hundreds of kilometres by plate tectonics down into the mantle.

“It shows that there is a gigantic recycling route that brings elements from Earth’s surface down into the Earth, and then occasionally returns beautiful diamonds to the surface, as passengers in volcanic eruptions,” Smith said.

No Buyer for 3ct. Blue Diamond at Sotheby’s

3.01 carat fancy vivid blue diamond

A 3.01-carat, fancy-vivid-blue diamond ring, carrying a high estimate of $6.3 million was among a number of headline items that failed to find buyers at Sotheby’s Geneva auction.

Sotheby’s withdrew the stone from Tuesday’s Magnificent Jewels and Noble Jewels Part II at the request of the consigner, it told Rapaport News Wednesday. The sale, which achieved a total of $12.4 million, was the auction house’s first live event since the onset of the coronavirus pandemic, and followed Part I, which took place online.

An oval-shaped, 21.56-carat, D-color, VVS1-clarity diamond ring by Lorraine Schwartz, valued at $1.5 million to $2 million, also went unsold. Other colored diamonds were not purchased, including a duet ring set with a pear-shaped, 3.03-carat, fancy-intense-blue diamond and a pear-shaped, 2.82-carat, D-color, VVS1-clarity diamond, as well as a step-cut, fancy-vivid-yellow diamond ring weighing 16.43 carats.

Meanwhile, the top-selling lot at the sale was a marquise-shaped, 7-carat, fancy-intense-pink diamond ring, which was auctioned for the first time after spending 30 years in a private collection. The piece sold for $2.8 million, within its $2.4 million to $3.4 million estimate.

Other notable items included a pear-shaped, 5.29-carat, fancy-grey-blue diamond ring, which garnered $2.1 million, beating its $1.2 million high estimate. A pair of cushion-shaped, D-color, VVS2-clarity diamond earrings, weighing 13.50 carats and 13.52 carats, fetched $1.5 million against an estimate of $1.2 million to $1.8 million.

Sapphires also proved popular, with a cushion-shaped, 105.89-carat ring going for $1.7 million, more than double its $670,000 high estimate. A cushion-shaped, 16.11-carat sapphire ring bracketed by diamonds also sailed past its $490,000 upper valuation, achieving $524,000.
