All GIA Reports to Be Digital by 2025

The Gemological Institute of America (GIA) plans to convert all of its paper reports to digital within the next three years, beginning with its Diamond Dossier in 2023.

The digital reports, which it will link to an app, will be more secure than their paper counterparts, the GIA said Tuesday. They will be paired with a new inscription-matching service, called GIA Match iD. This feature captures a diamond’s inscription image and links the stone to its GIA report using artificial intelligence (AI).

As each report category is introduced in digital form, the printed reports will be discontinued, the GIA told Rapaport News. However, some specialty services, such as the Monograph reports and notable letters, will continue to be available in printed versions.

“Digital reports…build on our decades of innovation and move our consumer protection mission forward,” said GIA CEO Susan Jacques. “This important transformation allows GIA to offer consumers a truly modern and engaging experience while helping our industry progress toward a more sustainable future.”

Starting in January 2023, the new Diamond Dossier service will offer a fully digital report, including the 4Cs; the app, which enables retailers and consumers to view, save and share information for their diamonds; and the Match iD instrument.

The elimination of GIA paper reports will save 20 tons of paper and 18.5 tons of plastic each year, the GIA said. It will also reduce transportation-related carbon emissions, the institute added.

US Demand, Uncertain Supply Buoy Diamond Prices

Diamond trading was stable in May despite concerns about inflation, rising interest rates and slumping stock markets. Polished prices initially declined but later steadied as dealers anticipated supply shortages resulting from Russian sanctions.

The RapNet Diamond Index (RAPI™) for 1-carat diamonds slid 0.5% in May but was 9.3% higher on June 1 than at the beginning of the year.

RapNet Diamond Index (RAPI™)
	May	Year to date Jan. 1 to June 1	Year on year June 1, 2020, to June 1 2021
RAPI 0.30 ct.	0.6%	1.3%	-0.1%
RAPI 0.50 ct.	-0.3%	5.8%	8.2%
RAPI 1 ct.	-0.5%	9.3%	22.1%
RAPI 3 ct.	-0.3%	10.6%	25.7%

US demand is supporting the market even as economic uncertainty sets in. Expectations are rising for the Las Vegas shows, which begin June 8. Dealers hope the positive sentiment will boost trading in the second half of the year. Chinese wholesalers remain cautious as activity resumes after the country’s Covid-19 lockdowns.

Inventory levels are high but have decreased in select categories. The number of diamonds on RapNet stood at 1.8 million as of June 1, up 43% from a year earlier. The quantity of 0.30-carat, D- to H-color, IF- to VS-clarity goods fell 14% in May; 0.50-carat diamonds in the same range declined 11%. Both categories were still significantly above last year’s levels.

While the sanctions on Russian goods have not yet caused notable polished scarcities, shortages are likely in the coming months. Rough supply has dropped since Alrosa canceled its March and April sales. Prices at rough auctions have increased — particularly in the small-diamond category, which Alrosa dominates. De Beers raised prices of small rough at its latest sight from June 6 to 10.

The market is splitting into two segments: Russian and non-Russian goods. Some big cutters are finding ways to buy Alrosa rough in order to serve centers that remain open to buying Russian-origin polished. These diamonds will likely sell at a discount to non-sanctioned ones.

US and European jewelers and brands may have difficulty filling their sourcing requirements in the coming months without Russian supply. This will lend further support to diamond prices.

Gem Diamonds unearths 125-carat diamond in Lesotho

Africa-focused Gem Diamonds has found a 125 carat rough stone at its Letšeng mine in Lesotho, the miner’s second rock over 100 carats mined this year.

The company, known for the recovery of large, high quality stones in 2020, has seen output of high quality diamonds surpassing the 100 carat mark become less frequent over the past year.

In 2021, Gem Diamonds found only six of such diamonds at Letšeng, compared to the 16 it discovered in 2020.

The find comes as prices for small diamonds have jumped about 20% since the start of March, as cutters, polishers and traders struggle to source stones outside Russia.

State owned Russian miner Alrosa, the world’s top diamond producer by output, was hit with US sanctions following Moscow’s invasion of Ukraine.

Higher prices for lower end stones are good news for miners, but not a game changer, experts say. While every mine is different, a general rule is that 20% of production the best stones account for about 80% of profits.

Since acquiring Letšeng in 2006, the company has found more than 60 white gem quality diamonds over 100 carats each, with 16 of them recovered last year. At an average elevation of 3,100 metres (10,000 feet) above sea level, Letšeng is also one of the world’s highest diamond mines.

DRC Embarks on Mine-to-Market Program for Artisanal Diamond Miners

The first steps towards setting up a traceability program have been taken in Democratic Republic Congo (DRC), which dominates the world’s supply of diamonds from artisanal and small-scale mining (ASM).

A pilot project involving Antwerp World Diamond Centre (AWDC), the DRC mining ministry and tech company Everledger aims to establish a fully transparent value chain in a country which has a diamond sector vulnerable to human rights violations, poor working conditions, corruption and opaque or illicit trade.
The project, called OrigemA, is initially being funded by the AWDC and will focus on transparency, sustainability and fair trade.
The DRC is the largest producer of artisanal mined diamonds in the world, accounting for nearly 70 per cent of global ASM production, which in turn constitutes an estimated 15 to 20% of the total diamond production in the world.
DRC’s mining minister Antoinette N’Samba Kalambayi said stakeholders “will work with the other partners to create a legal and fiscal framework that allows efficient formalization, combatting corruption, eradicating logistical hurdles, and increasing transparency in financial and fiscal flows.”
Karen Rentmeesters, AWDC’s head of industry relations, said: “This bottom-up, collaborative approach ensures that we create a model that considers the realities of artisanal, small-scale mining in remote regions and that the resulting blueprint can be scaled up and replicated in the field.”

IGI Grades Largest Polished Lab-Grown Diamond

*The three lab-grown diamonds from Greenlab*

The International Gemological Institute (IGI) has graded a 27-carat lab-grown stone that it claims is the world’s largest polished synthetic diamond.

Indian lab-grown company Greenlab created the marquise step-cut, 27.27-carat diamond, named Om, IGI said Wednesday. The stone, which has no color enhancement, was grown using chemical vapor deposition (CVD).

Along with Om, the IGI graded two additional lab-grown stones submitted by Greenlab, including Shivaya, an emerald-cut diamond weighing 20.24 carats, and Namah, a pear rose-cut, 15.16-carat polished. Greenlab plans to display the diamonds at the JCK Las Vegas show, it noted.

Previously, the largest known polished CVD diamond was a princess-cut, 16.41-carat, G-color, VVS2-clarity stone created by Shanghai Zhengshi Technology. The Gemological Institute of America (GIA) graded the stone in January.

At the time, the largest polished lab-grown diamond of any sort the GIA had examined was a cushion-cut, 20.23-carat, fancy-vivid-yellowish-orange, VS2-clarity diamond created using the High Pressure-High Temperature (HPHT) method in 2019.

Gem Diamonds finds 129-carat diamond in Lesotho

Africa focused Gem Diamonds has found a 129 carat rough stone at its Letšeng mine in Lesotho, the miner’s first one over 100 carats mined this year.

The high quality white diamond was recovered at the site over the weekend, Gem Diamonds said. The company, known for the recovery of large, high quality stones in 2020, has seen output of those diamonds become less frequent over the past year.

In 2021, Gem Diamonds found only six diamonds over 100 carats at Letšeng. This compares to 16 rocks of more than 100 carats discovered in 2020.

The find comes as prices for small diamonds have jumped about 20% since the start of March, as cutters, polishers and traders struggle to source stones outside Russia.

State-owned Alrosa, the world’s top diamond producer by output, was hit with US sanctions following Moscow’s invasion of Ukraine.

Lucapa says 204 carat diamond recovered at Mothae mine in Lesotho

Lucapa Diamond Company yesterday announced the recovery of a 204 carat diamond from the Mothae mine in Lesotho.

According to the company’s statement, the 204 carat white stone is the eighth +100 carat diamond and third +200 carat to be recovered from the Mothae mine since commercial mining commenced in January 2019, underlining its unique large stone nature.

Lucapa Diamond Company is an ASX listed diamond miner and explorer with assets in Africa and Australia. It has interests in two producing diamond mines in Angola (Lulo) and Lesotho (Mothae).

“The large, high-value diamonds produced from these two niche African diamond mines attract some of the highest prices per carat for rough diamonds globally,” the company said.

The Lulo mine has been in commercial production since 2015, while the Mothae mine commenced commercial production in 2019.

Botswana sees Russian diamond ban opening door to synthetic gems

*Mirny, Sakha Republic, Russian Rough Dimaonds*

Botswana, Africa’s top diamond producer, sees a prolonged ban on Russian diamonds opening the way for synthetic gems to expand market share, the country’s minister told a mining conference on Monday.

The United States, the world’s largest market for natural diamonds, imposed sanctions on Russia’s state-controlled Alrosa in April, aiming to cut off a source of revenue for Moscow after its February invasion of Ukraine.

Alrosa, the world’s largest producer of rough diamonds, accounted for about 30% of global output in 2021.

Botswana’s Minister of Minerals and Energy Lefoko Moagi said the ban on Russia diamonds might push prices up to the benefit of rival producers but he also said the gap would be hard to fill.

“We see the 30% gap that will be left by the ban being plugged by something else that is not natural. And for us that will be a challenge,” he said.

Jacob Thamage, head of Botswana’s Diamond Hub, said uncertainty over the Ukraine conflict makes it difficult for Botswana and other natural diamond miners to fill the supply gap as ramping up operations requires significant investment.

“You don’t want to invest a lot of money to up-scale and then the war ends the next day,” Thamage said. “We also see the higher prices pushing consumers to substitutes such as the synthetics and this can cause problems for us if we cede the market to unnatural stones.”

Sales at Debswana, a joint venture between Anglo American unit De Beers and Botswana’s government, accounts for almost all of Botswana diamonds exports. These stood at $3.466 billion in 2021 compared with $2.120 billion in 2020.

Thamage also fears that consumers might start to shun natural diamonds due to traceability issues.

“There is an increased fear that buyers of diamonds will begin to treat all natural diamonds as conflict diamonds and therefore shift to unnatural diamonds,” he said.

‘The Rock,’ the largest white diamond ever auctioned, sells for $21.9 million

he largest white diamond to ever come up for auction has been sold for $21.9 million USD at Christie’s in Geneva.
The 228.31-carat, pear shaped gemstone dubbed “The Rock” originated from South Africa, where some of the largest diamonds in the world have been found, including the pear-shaped “Star of Africa” and rose cushion cut “Golden Jubilee.”
“The Rock” is about the size of a golf ball and was previously worn as a lavish Cartier necklace by its former owner. Along with the pear-shaped stone, the new owner will also receive a round diamond and platinum pendant mounting from the French luxury brand.
World’s largest blue diamond to come to auction has sold for $57.5 million
Ahead of the sale, the head of Christie’s jewelry department in Geneva, Max Fawcett, explained why “The Rock” is a particularly unique stone.
“Often with these largest stones, they sacrifice some of the shape in order to keep the weight,” he told Reuters. “This is a perfectly symmetrical pear-shape form and… one of the rarest gems ever to be sold at auction.”

Angolan diamond mine says Russia sanctions could hurt operations

Endiama, which holds the exclusive concession for diamond mining rights in Angola, has already flagged an almost one-third reduction in diamond output this year.

Angola’s state-run diamond miner Endiama could face a hit to its operations as Western sanctions on Russia could delay supplies of parts and machinery, according to a government brochure.

The government publication was made available at the Mining Indaba conference in Cape Town on Monday.

Western nations have unleashed crippling economic sanctions against Russia after Moscow’s invasion of Ukraine in late February.

Endiama, which holds the exclusive concession for diamond mining rights in Angola, has already flagged an almost one-third reduction in diamond output to 10.05 million carats this year, from a forecast 13.8 million carats.

The company expects revenue of about $1.42bn from the sale of its diamonds this year.

“One of the great challenges for 2022 will certainly be to maintain the sustainability of the mines while the war between Russia and Ukraine lasts,” said the government brochure, “since the sanctions that the United States and Western countries have imposed on Russia may affect some national mining companies, delaying the supply of some machinery, parts and spares.”

Endiama has signed contracts with Rio Tinto to explore its Chiri mine in the Angolan province of Lunda Norte, while another project, Luaxe, was also expected to begin pilot production, it added, without providing a timeline.

Last month, diamond miner De Beers signed two mineral investment contracts with the Angolan government, the Anglo American subsidiary said ahead of a return to the country it left in 2012.
