The 118.74 carats diamond recovered in late April.
Africa-focused miner Gem Diamonds (LON: GEMD) has unearthed a new major Type II white diamond at its prolific Letšeng mine in Lesotho, barely six days after the previous find.
The 118.74-carat diamond is the fifth greater than 100-carat precious stone recovered this year at the operation, the company said.
Type IIa diamonds are the most valued and collectable precious gemstones, as they contain either very little or no nitrogen atoms in their crystal structure. Boart diamonds are stones of low quality that are used in powder form as an abrasive.
The prolific Letšeng mine is one of the world’s ten largest diamond operations by revenue. At 3,100 metres (10,000 feet) above sea level, it is also one of the world’s most elevated diamond mines.
Diamond miners are going through a rough patch as US and Chinese demand for diamond jewellery continues to be weak and the popularity of cheaper laboratory grown diamonds continues to rise.
In 2015, man-made diamonds had barely made an appearance as a competitor to natural diamonds. By last year, these stones accounted for more than 10% of the global diamond jewelry market, according to industry specialist Paul Zimnisky.
The market values of small to medium diamond mining companies, including Canada’s Lucara (TSX: LUC), South Africa’s Petra (LON: PDL), and Gem Diamonds itself, are around $100 million or less. This is only about a third or a fourth of the price the large stones they aim to find may be worth.
Gem Diamonds Limited (LSE: GEMD) is pleased to announce the recovery of a high quality 113 carat white Type II diamond, recovered at the Letšeng mine in Lesotho on 17 February 2024.

Together with the 295 carat high quality Type II white diamond recovered on 8 January 2024 and a 139 carat low quality Boart diamond recovered on 17 January 2024, the 113 carat is the third greater than 100 carat diamond recovered to date this year.
Gem Diamonds has recovered a 117.47-carat rough from its Letšeng mine in Lesotho, its fourth over 100 carats so far this year.
The miner discovered the gem-quality, type IIa diamond on October 29, it said Tuesday. The find follows that of a 101.96-carat high-quality rough on September 28, and a 163.91-carat yellow diamond on June 22. The company also unearthed a 122-carat stone on March 5.
Letšeng has been known for producing high-quality rough diamonds topping the 100-carat mark, but recently that supply has been dwindling. However, the newest recovery brings this year’s total to a tie with last year, when the miner also retrieved four diamonds in that category. That compares with six in 2021 and 16 in 2020.
The declining number of special-size stones has put a dent in the company’s revenue, with sales falling 28% year on year to $71.8 million in the first six months of 2023. The miner incurred a loss of $1 million, versus a profit of $3.8 million during the same period in 2022.

While Letšeng had previously been known for producing high-quality rough diamonds topping the 100-carat mark, that supply has been declining. Last year, the miner retrieved only four diamonds of that magnitude, versus six in 2021 and 16 in 2020.

The Baselworld fair has received much criticism in recent years, but one of the final shows before its public implosion appears to have facilitated a diamond deal that counts among the biggest in history.
Antwerp-based manufacturers Taché and Samir Gems came to the March 2018 exhibition with the exquisite Lesotho Legend, a 910-carat, type IIa diamond they had bought together from Gem Diamonds for $40 million earlier that month. At the time, jewelers such as Graff and Harry Winston dominated the big-stone market. Displaying the massive rough at the prestigious Swiss event could help drum up broader interest in the category, Taché and Samir believed.
“We felt that the market was a bit saturated between one or two players,” says Jean-Jacques Taché, managing director for sales at Taché, from his office in Tel Aviv, Israel. “So we thought, let’s bring it to Basel, let’s…showcase the [rough], and let’s see the reactions.”
Plenty of visitors wanted selfies with the stone, which came from the famous Letšeng mine in Lesotho. Some suggested buying a sliver of the piece — polished of, say, 5 to 20 carats, Taché recalls. However, “none of them were really committed at that point to enter into a venture.”
The exception was Van Cleef & Arpels, a Richemont-owned luxury brand that, Taché explains, had been somewhat pulling back from big stones in recent years.
“From the minute they saw it, [Van Cleef] started to talk about the idea that they had,” the executive adds. The timing was perfect: The luxury brand had just finished a ruby collection and was seeking a new project on which to spend a few years. “Sometimes you need a lot of things to happen at the same time in order to make it a success.”
The buying executive representing Van Cleef needed approval from Nicolas Bos, the brand’s CEO, and the Richemont team. Not long after the event, Taché, Samir and Van Cleef signed an agreement calling for the jeweler to buy the final polished. The condition was that the finished goods met the French house’s high quality criteria.
Long wait
Only this month did Van Cleef reveal the finished jewelry, more than four years after the initial pitch. The result was a unique collection of 25 Mystery Set jewels featuring 67 D-flawless diamonds. The largest is an oval, 79.35-carat stone that takes pride of place in a necklace called Atours Mystérieux, meaning “mysterious attire.” The smallest is 0.29 carats. The parties have not disclosed the polished sale price.
Taché and Samir both took heavy risks by splurging on the rough back in 2018. (Gem Diamonds publicly named Samir as the buyer: As is often the case, a miner only invoices one entity, but the purchase was really a 50:50 partnership.)
The two companies have a long-standing collaboration, having also bought the 341.9-carat Queen of Kalahari together from Lucara Diamond Corp. a few years earlier. They sold that polished to Chopard. Samir has its expertise in purchasing large rough stones; Taché specializes more in relationships with the top jewelry brands.
“We’re the most successful Jewish-Indian partnership on the market, by far,” says Taché.
They outsourced the cutting and polishing to Diamcad, an Antwerp firm that also manufactured the Lesedi La Rona for Graff. The goods went for grading at the Gemological Institute of America (GIA) in New York, where all the stones received Diamond Origin Reports stating that they were from the Lesotho Legend.
Van Cleef took delivery of the polished as each stone was ready between January 2019 and March 2020, Taché notes. However, Covid-19 delayed the launch, as Van Cleef had been hoping to hold roadshows.

Quality over size
The manufacturers agreed to include Van Cleef throughout the process, including in the planning and design. The Taché and Samir teams even traveled with Van Cleef’s Bos to Lesotho in May 2019 to experience the Letšeng mine and learn about the local community there.
The brand would accept only flawless goods, so quality became a higher priority than size. The planning process, which took about seven months in 2018, saw the parties review around 180 possible combinations of outcomes. None of them included any “monster” stones, they note.
“Instead of 67 stones, you could also have a model with probably 12 pieces only, but [it would have been] much less interesting in terms of creation,” Taché continues.
There were other complicating factors. Van Cleef tends to avoid round and heart-shaped diamonds. It also wanted matching pairs: “Practically every stone in this collection between 10 and 30 carats is a couple,” he points out.
“If we went for something which was 100-carats-plus, we would have had to go into the VS range,” comments Antwerp-based Anjal Bhansali, managing director at Samir. The team even broke up a stone of roughly 75 carats into two matching stones weighing around 30 carats each, Bhansali reveals.
Boost for big stones
The manufacturers hope the collection will succeed in reinvigorating the large-diamond sector, expanding it beyond the traditional two giants.
“The goal is to create more awareness for big stones in the market and to bring in new players,” Taché concludes. “We started it with Chopard. We [are continuing] this now with Van Cleef.”
It’s unclear whether the Basel show will ever return. However, everyone involved in the Lesotho Legend project will agree that the 2018 edition was well worth it.
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.
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.

Gem Diamonds’ revenue in Q1 2022 (ending March 2022) has gone up 4% quarter-on-quarter and 19% year-on-year to $52.1 million, IDEX Online reports.
The miner, which owns 70% of the Letseng mine in Lesotho, sold 28,461 carats during the quarter – a rise when compared to the 24,790 carats it sold in the previous quarter. However, prices fell from $2,018 to $1,831, according to the report.
Clifford Elphick, Gem Diamonds’ CEO, said: “We remain confident about the outlook for diamond prices, particularly for Letseng’s large high-value diamonds with an average price of $1,831 per carat achieved during the period. Prices achieved on a like-for-like basis continued the largely upward trend from 2021.”
Gem Diamonds has unearthed two large rough stones from its Letšeng mine in Lesotho, marking the fourth and fifth diamonds from the deposit over 100 carats this year.
The stones — weighing 245 and 102 carats — are high-quality, white, type II diamonds, the miner said Monday. The company found both stones on the same day.
The recoveries follow that of two diamonds weighing 370 and 254 carats in May. The company also discovered a 146.9-carat rough in January.
Output of large stones has been sluggish in the first half of the year as Gem Diamonds mined lower-value areas of the deposit, it explained. In the first six months of the year, the company unearthed three 100-carat-plus diamonds, compared to seven in the same period of 2020. Last year, Gem Diamonds recovered 13 stones greater than 100 carats by September 30, and 16 for the full year.

The auction came as the Mountain Kingdom explores how to ensure diamond mines are at least 51 percent-owned by locals, which will include the entry of small-scale miners into the sector.
Lesotho’s diamonds are usually auctioned in Antwerp, Belgium. Buyers from as far as the Netherlands and Israel were joined by those from neighbouring South Africa and locals at the inaugural auction.
Launched by Deputy Prime Minister Mathibeli Mokhothu, the auction sold off diamonds collected from the public and those confiscated by the police in recent months. Of the 493 diamonds auctioned, 140 were voluntarily handed over by the public while 353 were confiscated by the police.
The government offered an amnesty from November 2020 to March 2021 to anyone in possession of undocumented diamonds, allowing them to hand the gems over without fear of prosecution. The auction was held from May 27 to 29.
Mining Minister Serialong Qoo said all revenue from the confiscated diamonds would be forfeited to the state and proceeds from gems voluntarily handed to the government would be paid into the holders’ bank accounts.
“I am very delighted that this day has finally come after it was initially delayed by the COVID-19 pandemic. This is a big move as parliament has now embraced the idea of letting Basotho mine with their picks and shovels legally,” said Minister Qoo.
Mining Ministry spokesperson Ms ‘Makananelo Motseko this week said a final report on the auction was being compiled and would be made public.
At the auction, Deputy PM Mr Mokhothu said, “We hope this local auctioning will spell the end for illegal diamond dealing as trade will be done securely and legally. This occasion gives me hope that soon, all of Lesotho’s diamonds will be sold in-country and benefit it economically.”
He also said Lesotho should move towards ensuring that at least 51 percent of shareholding in the diamond mines is held locally while investors would hold the remaining 49 percent.

Gem Diamonds has recovered a 370-carat rough stone in Lesotho, the second over 100 carats in one week.
The “high-quality,” white, type II diamond came from the company’s Letšeng mine, known for producing large diamonds, it said Monday. The new find follows the discovery of a high-quality, 254-carat, white, type II diamond the miner reported on May 4.
The miner has unearthed three 100-carat-plus diamonds so far this year, including a 146.9-carat rough in January. Although output of large stones was sluggish in the first quarter as the company mined lower-value areas, it is still ahead of last year’s discovery of two stones greater than 100 carats by the middle of May.
In 2020, Gem Diamonds produced a total of 16 diamonds larger than 100 carats.

Gem Diamonds has announced the recovery of a high quality 254 carat Type II, white diamond, from the Letšeng mine in Lesotho, the highest dollar per carat kimberlite diamond mine in the world.
“It is pleasing to see that carat production during the Q1,2021 is up some 11% on the same period in 2020 and the average price of US$1 630 per carat is also slightly up on Q1,2020,” said CEO, Clifford Elphick in last month’s Q1,2021 report.
“Although the production from the mining mix was not as impressive as the second half of 2020, with fewer large diamonds recovered due to the areas accessed under the mining plan, prices achieved on a like for like basis remained strong for Letšeng’s high value diamond production.
“It is anticipated that the mining mix should improve over the coming months as the richer parts of the Satellite pit are accessed in accordance with the mine plan.”

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.
