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.

Record Lab-Grown Stone Turns Up at GIA

The Gemological Institute of America (GIA) recently graded the largest known synthetic diamond to be created using chemical vapor deposition (CVD), it claimed Wednesday.

The stone, produced by Shanghai Zhengshi Technology, is a princess-cut, 16.41 carat, G colour, VVS2 clarity lab grown diamond. Spectroscopic readings the GIA performed confirmed the stone had no post growth treatments to improve the color, it noted.

“The first CVD diamond I examined in 2003 was a 0.23 carat pear shape, with clear brown colour,” said Wuyi Wang, GIA vice president of research and development. “This 16.41 carat laboratory grown diamond demonstrates the advances in CVD growth technology. This achievement has important implications for the many scientific and industrial applications for high quality laboratory grown diamonds.”

The previous record for a synthetic diamond grown using CVD was held by an emerald cut, 14.60 carat, F colour, VS2 clarity diamond, which was produced in India and graded by the International Gemological Institute (IGI). Meanwhile, the record for the largest lab grown diamond the GIA has examined was in 2019 for a cushion cut, 20.23 carat, fancy vivid yellowish orange, VS2 clarity stone made using High Pressure High Temperature (HPHT).

Natural-Diamond Trade Hits Back at Pandora

Leading trade organizations have lashed out at Pandora’s recent statements about lab-grown stones, claiming the retailer misrepresented natural diamonds and caused harm to the industry.

Pandora announced it would no longer sell mined diamonds and would instead stock synthetics, linking the decision to its environmental goals. The launch of a lab-grown line will help “transform the market for diamond jewelry with affordable, sustainably created products,” the Danish jeweler asserted last week.

Pandora’s proclamation wrongly positioned lab-grown as an “ethical choice versus natural diamonds,” five jewelry groups said in a joint statement Friday. The signatories were the Responsible Jewellery Council (RJC), the Natural Diamond Council (NDC), the World Jewellery Confederation (CIBJO), the World Diamond Council (WDC) and the International Diamond Manufacturers Association (IDMA).

The diamond industry employs tens of millions of people around the world, the organizations pointed out. The communities that benefit from the sector need its support “more than ever” given the hardship resulting from Covid-19, they added.

“The misleading narrative created by the Pandora announcement implying the natural-diamond industry is…less ethical and the impetus behind Pandora’s move to lab-grown diamonds, particularly given the inconsequential [quantity] of diamonds Pandora features in its collections, can have unintended but substantial consequences on communities in developing nations,” the groups said. “The industry organizations have called upon Pandora to support communities by correcting the record.”

Pandora used mined diamonds in about 50,000 of the 85 million pieces it created in 2020, it said.

Pandora was not immediately available for comment.

Pandora Taps Lab-Grown, Drops Mined Diamonds

Pandora has launched its first lab-grown jewelry line and pledged to cease using mined diamonds in any of the company’s pieces.

The Danish jeweler will introduce the collection, Pandora Brilliance, in the UK on May 6, before debuting it globally in 2022, it said Tuesday. Pandora believes offering synthetics will make its products more accessible to a wider audience looking for more affordable and sustainable diamond jewelry, it explained.

“Pandora continues its quest to make incredible jewelry available for more people,” said Pandora CEO Alexander Lacik. “[Pandora Brilliance] is a new collection of beautifully designed jewelry featuring lab-created diamonds. They are as much a symbol of innovation and progress as they are of enduring beauty and stand as a testament to our ongoing and ambitious sustainability agenda. Diamonds are not only forever, but for everyone.”

As part of its effort to be carbon-neutral, Pandora will use synthetic diamonds that have been grown with more than 60% renewable energy. The jeweler expects to use stones made using 100% renewable energy by the time it launches the line globally, it noted.

The new collection includes rings, bangles, necklaces and earrings, each featuring a single lab-grown diamond ranging from 0.15 to 1 carat, with prices starting at GBP 250 ($347), Pandora added.

Mumbai Bourse to Vote on Lifting Synthetics Ban

Mumbai’s Bharat Diamond Bourse (BDB) is on the verge of allowing lab-grown trading, with members due to vote on the matter next week.

The board of the world’s largest diamond hub has recommended the move, arguing that better detection and increased awareness have made it easier to segregate synthetic stones from natural ones. The poll will take place at the annual general meeting (AGM) at the BDB on December 28, according to the exchange’s annual report, which it released last week.

The bourse banned synthetics in 2015, but has been reconsidering the rule for more than two years and holding talks with India’s Natural Diamond Monitoring Committee on how to keep watch of the trade. The board received numerous requests for a meeting in which members could pass the amendment, BDB president Anoop Mehta told Rapaport News Monday.

“I think the vote result will be positive, because a lot of people want to diversify,” Mehta commented.

In the past, “you didn’t have many detection machines, and they were pretty expensive,” he added. “Detection…has gotten much more accessible and reasonable.”

However, companies won’t be able to start trading in synthetics immediately: They will have to apply for this right, Mehta explained. Companies active in both sectors must have detection equipment and keep natural and lab-grown stones in separate rooms, with clear markings on the door to indicate what’s inside. The BDB will cancel the membership of companies that flout the rules.

Meanwhile, the BDB board has recommended removing “natural” from its definition of diamonds, bringing it in line with industry standards, Mehta added. This will also be included in next week’s vote.

Buy Laboratory created diamonds

Largest ever CVD laboratory-grown diamond hailed a “remarkable achievement”

The International Gemological Institute’s (IGI) Hong Kong laboratory has certified the largest chemical vapor deposition (CVD) laboratory-grown diamond received to date.

With a finished weight of 12.75 carats, this collection-quality man-made gemstone was fashioned from a 46.20 carat CVD-grown rough crystal.

According to its creator, Shanghai Zhengshi Technology, it is the largest CVD lab-grown diamond ever produced.

“For the past 15 years, IGI has been at the forefront of lab-grown certification and education,” stated IGI CEO, Roland Lorie. “With this milestone, the Institute continues to establish itself as the prominent leader in the industry and opens the door for future opportunities to exceed current gemological standards.”

IGI gemologists confirmed the 12.75ct stone was Type IIa, giving it exceptional chemical purity and transparency, with VVS2 clarity, F color, and triple-excellent marks in cut-quality and finish.

Following detailed scientific analysis, the laboratory substantiated that the stone had not undergone any post-growth treatments, so it can be categorised as a pure CVD diamond.

“A laboratory-grown diamond of this carat weight, with such a high clarity and color grade, is a remarkable achievement in CVD cultivated diamond technology,” said IGI Hong Kong managing director, Bob Van Es. “As the industry leader in the certification of laboratory-grown diamonds, IGI will continue to follow these new developments closely.”

This news comes only three months after the IGI analysed the Guinness World Record-holding biggest black lab-grown diamond.

Blue Nile to Sell Lightbox Lab-Grown Diamonds

Blue Nile has launched an exclusive line of Lightbox lab-grown diamond jewelry, its first foray into synthetics in its 21-year history.

De Beers-owned Lightbox seemed like the obvious choice for a partner, given the alignment of the two companies’ perspectives, Blue Nile CEO Sean Kell told Rapaport News Thursday.

“We’ve been watching the lab-grown diamond market for some time. We think both natural diamonds and lab-grown diamonds have a place in the market,” he noted. “When we first discussed stepping into the lab-grown space, Lightbox was the only brand partner that came to mind.”

The online jeweler’s partnership with the lab-grown brand is an effort to offer a greater range of products to its customers.

“The launch of the Blue Nile Lightbox collection…now adds even more variety, quality and value for our customers as we head into the new year,” Kell said. “[This] will further expand and transform [our] product assortment to meet the needs of evolving consumers in the jewelry space.”

The collection will feature new and exclusive styles of jewelry, including earring, pendants, bracelets and rings, set with white, blue or pink lab-grown diamonds in 14-karat white or yellow gold. The pieces, which range from $600 to $1,750, will be available both online and in Blue Nile’s newly launched and soon-to-open showrooms, Kell noted.

While Blue Nile’s Lightbox collection will feature fashion jewelry, it will not include engagement rings, for now.

“At this time we do not [plan to carry them],” Kell added. “We think of lab-grown diamonds versus natural diamonds as two separate categories. Our belief is consumers will continue to select natural diamonds for engagement and significant milestones, whereas lab-grown diamonds…will give shoppers an opportunity to expand their jewelry box with…jewelry they can wear every day.”

Lightbox opens its doors

The launch coincides with the debut of Lightbox’s new 60,000-square-foot manufacturing facility in Gresham, Oregon. The synthetics maker began production at the facility during the summer, as construction was being completed, and plans to ramp up output at the $94 million plant to reach 200,000 carats annually.

“Manufacturing lab-grown diamonds in the US was a goal from the beginning,” said Lightbox CEO Steve Coe. “With this facility and our…partnership with Blue Nile, we have an incredible opportunity to grow our business, improve consumer education and further establish Lightbox as the leading lab-grown diamond jewelry brand.”

Lightbox first dipped its toe in the retail space through partnerships with Bloomingdale’s and Reeds Jewelers. Earlier this month, the company announced an expansion to 10 independent retail jewelers in the US and Canada, a move it believes will enable it to gain insight into different audience segments, and learn how they shop and which products appeal to them most.

While the De Beers brand is currently focused on retail partnerships, Coe told Rapaport News he wouldn’t rule out the possibility of “one or two” self-operated stores “at some point.”

The company is also looking to expand its product offering, including creating larger sizes for its lab-grown diamonds, which currently weigh up to 1 carat.

“The biggest priority for us in 2021 is exploring the opportunity to go to larger sizes,” Coe noted. “That is something we are working on — going up to 2 carats.”

Meanwhile, the lab-grown brand is also looking to extend its color range beyond white, blue and pink.

“Our scientists are already looking at other color options, and in the lab at least, we’ve made yellows, greens, violets and other shades,” Coe added. “But that’s more likely in the 2022, 2023 timeframe, probably.”

GIA Unveils New Lab-Grown Reports

The new GIA lab-grown diamond reports. (GIA)

The Gemological Institute of America (GIA) has launched its new grading reports for lab-grown diamonds, offering an updated look and format.

The new documents, branded “LGDR by GIA,” come in digital-only form and use specific color and clarity scores rather than the descriptive terms and ranges that appeared in its previous reports, the organization said Tuesday.

“The evolution of GIA’s reports for laboratory-grown diamonds is fully aligned with our mission to protect all consumers,” said Susan Jacques, GIA president and CEO. “Everyone who purchases gemstone jewelry — whether natural or laboratory-grown — expects and deserves the information, confidence and protection that come with a GIA report.”

The offering includes two different Laboratory-Grown Diamond Reports for colorless synthetic diamonds — a standard report and a dossier — and two for colored diamonds: one with plot diagrams and one without.

Notably, the GIA avoids calling the documents “grading reports” — a term it reserves for natural diamonds. Earlier this week, the World Jewellery Confederation (CIBJO) recommended that laboratories use that term only for natural stones and instead call synthetics reports “Laboratory-Grown Diamond Product Specifications,” arguing that the concept of grading implies rarity.

“The color and clarity specifications for laboratory-grown diamonds are described on the same scale as GIA grading reports for natural diamonds, but that does not correlate to nature’s continuum of rarity,” the GIA noted.

The reports state that a stone was created by chemical vapor deposition (CVD) or High Pressure-High Temperature (HPHT) and that it may include post-growth treatments to change the color. Each report also comes with a QR code linking to a custom page on GIA’s website with information about lab-grown diamonds.

Each stone will also receive a laser inscription with the report number and the words “laboratory-grown,” unless another acceptable term already appears on the girdle.

‘Grading’ Is Just for Natural Diamonds, Says CIBJO

Laboratories should reserve the term “grading report” for natural diamonds rather than lab-grown stones, the World Jewellery Confederation (CIBJO) has urged.

Lab-grown diamonds lack the rarity that underpins the concept of grading, CIBJO argued Tuesday. Instead, documents providing details of synthetics should be called “Laboratory-Grown Diamond Product Specifications,” the organization says in a new set of guidelines it released to the trade this week.

The standard grading report implies “a degree of rarity of the product,” a CIBJO spokesperson told Rapaport News. “But on the other hand, the consumer has a right to know what the components of the product are. The important element is that the term ‘grading’ is taken out.”

CIBJO’s board has made its new Laboratory-Grown Diamond Guidance available for review by affiliated companies and national associations, the organization said. The consultation phase is the final stage in a two-year process to create harmonized standards for man-made stones.

The rule book, which is not binding, also calls for laboratories to include extra information such as the name of the manufacturer, the country and method of manufacture (chemical vapor deposition or High Pressure-High Temperature), and information about post-growth treatments. It also recommends that the letters “LG” precede the color and clarity grades on the report to indicate the stones are lab-grown.

The guidelines deal with how to describe lab-grown diamonds and display them at events such as trade shows. They also provide recommendations on how companies should disclose the origin of the stones on invoices and consignment documents, and discuss synthetics detection technology.

“A key principle of the Laboratory-Grown Diamond Guidance is that, to ensure confidence, consumers must receive complete and unambiguous information about what they are buying, so that they can make consciously informed purchasing decisions,” CIBJO explained.

CIBJO’s Blue Book, a separate document on grading standards and terminology, notably kept “natural” in its definition of diamonds even after the US Federal Trade Commission dropped the word in 2018.

IGI Grades Record Black Lab-Grown Diamond

The International Gemological Institute (IGI) recently graded a 116-carat, black synthetic diamond that ranks as the largest lab-grown diamond of its color.

The 115.65-carat, type IIb stone was produced by UK-based Meylor Global using High Pressure-High Temperature (HPHT), and was accompanied by a second black lab-grown diamond weighing 109.58 carats, IGI said Wednesday.

“The innovative approach in physical chemistry of diamond growth, combined with sophisticated technological methods and advanced high-pressure equipment, allowed us to obtain record-breaking extra-large diamond single crystals, having in mind the idea of getting the biggest possible diamond plate,” said Meylor CEO Yuliya Kusher.

Meylor grew the diamonds as part of its “World’s Largest Black Diamonds Project,” which it began at the beginning of the year. However, it intends to try for a larger one in the future. The larger stone holds the Guinness World Record for its category, IGI reported.

“The significant milestone of [over 100 carats] in diamond size was achieved by our company in a very short time, and the next even more promising target of [over 200 carats] is right now under deep scientific investigation,” Kusher added.
