Gem Diamonds saw revenue and profits increase in FY2024, as high-value recoveries more than made up for persistent downward pressure of the diamond market.
In its Full Year 2024 Results published today (13 March), the UK-based miner reported a 10 per cent increase in revenue to $154.2m, largely driven by the sale of 13 +100-cts diamonds from its Letseng mine, in Lesotho.
Underlying EBITDA almost doubled to $29.7m and profit for the year increase from $1.6m to $8.1m.
Exceptional sales included an 11 carat pink diamond that was sold for $45,537 per carat, a 63 carat Type IIa white diamond that was sold for $41,007 per carat (the highest per carat price of the year) and a 113 carat Type IIa white diamond that was sold for $39,345 per carat.
The number of carats recovered during the year fell 4 per cent to 105,012.
Clifford Elphick, CEO at Gem, said: “2024 was another challenging year for the diamond market with decreasing rough and polished diamond prices. Our relentless focus on factors within our control – cost containment, operational efficiencies and appropriate capital allocation, has yielded pleasing results.”
Looking to the future, the company expects the market to remain under pressure during the year, with signs of a modest recovery in diamond prices.
More than half of all couples are now buying a lab grown diamond engagement ring, according to research carried out in January for The Knot wedding website.
A survey of almost 17,000 couples who married in 2024 found that 52 per cent opted for lab grown – the first time the balance has tipped from natural.
The figure for 2023 was 46 per cent and in 2019 it was just 12 per cent.
Couples are now spending less and getting bigger stones, according to the newly-published The Knot 2025 Real Weddings Study.
“The rise in popularity of lab-grown stones is fueling the decrease in the average cost of an engagement ring,” it says.
“2024 served as a continuation of that trend with proposers spending $5,200 on average for their ring. This is a decline from $5,500 in 2023, and $5,800 in 2022.
“Back in 2021, it was $6,000. Lab-grown stones typically begin at a lower price point than mined stones which is reflected in the average cost.
“A proposer purchasing a lab-grown engagement ring could expect to spend $4,900 versus spending $7,600, on average, for a mined diamond engagement ring.”
The average carat weight of an engagement ring bought last year was 1.7 carats, says the study, up from 1.5 carats in 2021.
The world’s largest pearl – weighing 27.65kg and valued at $98m is currently being displayed at a secret venue in Canada.
The Giga Pearl belongs to Toronto-based artist Abraham Reyes and is being shown as part of his Beneath The Surface exhibition of pearls, diamonds, and other precious stones.
The pearl was created 1,000 years ago by a giant clam, the largest of all bivalve molluscs (soft-bodied sea creatures with a hinged shell).
It has been certified by the GIA as the world’s largest natural blister pearl and holds the Guinness World Record.
Reyes inherited the pearl in 2019 from a great aunt after his grandfather bought it from a fisherman in the Philippines.
“I wanted to educate people about it,” Reyes said. “A lot of people don’t know that these giant clams exist because they’re endemic in the South Pacific. So this is something fascinating for people here in Toronto.”
The location of the Giga Pearl is being kept private for security reasons.
Chopard has unveiled a high jewelry collection crafted from one of the world’s largest emeralds.
The Swiss jeweler bought the 6,225-carat monster (1.22kg) from Gemfields in 2018 for an undisclosed sum.
The rough emerald, named Insofu -“elephant” in the local Bemba language – has since yielded 850 carats of gem quality emeralds, the first of which now feature in a 15-piece ensemble of necklaces, chokers, rings, earrings, a bracelet, and a watch.
Among the highlights of the Insofu collection are an elephant-shaped pendant with 50 carats of emeralds, and diamonds forming tusks, which can also be worn as a brooch; a Great Gatsby-inspired 4-in-1 necklace featuring a 15.53-carat octagonal emerald and a diamond choker with a 2.50-carat square-cut emerald.
Insofu was recovered by London-based Gemfields at its Kagem mine, in Zambia.
At the time Gemfields CEO Ian Harebottle said: “This is a unique find. The Insofu displays wonderful color and good translucency. Its sheer size, rich color and fine protective biotite shell makes it difficult to see deep into the gem.
“However, all indications suggest that the core of the emerald is competent and that it should yield a number of cut gems of significant size.”
It’s hard to swallow. In fact most of us would probably choke trying to down over 13 carats of Tiffany’s finest diamonds.
But that, allegedly, is how Jaythan Lawrence Gilder, aged 32, responded when cops in the US finally caught up with him last week.
He swallowed two pairs of earrings that had been stolen a couple of days earlier from the Tiffany & Co store at the Mall of Millenia, in Orlando, Florida, according to an arrest affidavit.
The Orlando Police Department say X-rays taken in custody appear to confirm their suspicions, though at the time of writing they were waiting for nature to take its course.
Gilder allegedly posed as the representative of an Orlando Magic basketball player so that he’d be taken to a private room to view high-value items.
Police said he grabbed a pair of 8.19-carat diamond earrings (valued at $609,500), and a 4.86-carat diamond pair (valued at $160,000) together with a ring valued at $587,000 (no description given).
He then pushed past an employee, according to the arrest affidavit, and escaped in a blue 2024 Mitsubishi Outlander.
Two days later he was apprehended by Florida Highway Patrol troopers who spotted his vehicle. He was arrested on 48 outstanding warrants for other offences, but the officers couldn’t immediately locate the stolen Tiffany jewelry.
While in custody, however, Gilder reportedly asked jail staff whether he was going to be charged with “what’s in my stomach”. A scan revealed “foreign objects” that appeared to be the stolen earrings.
“These foreign objects are suspected to be the Tiffany & Co earrings taken in the robbery but will need to be collected by WCSO (Washington County Sheriff’s Office, Florida) after they are passed through Gilder’s system prior to confirming,” the arrest report states.
It is indeed a bizarre crime, but it is not unique. In fact Joan Hannington, aka The Godmother, perfected the technique of diamond swallowing over a long and notorious criminal career.
It started when she was working in a high-end jewelry store in London in the 1970s. Realizing that the surveillance cameras weren’t working, she took a handful of loose diamonds from the safe on impulse and swallowed them. It later turned out they were worth £800,000.
“Swallowing diamonds was my life, my buzz, my drug,” she later wrote in her memoir I Am What I Am.
For the next 20 years she used the same technique – as described in her second memoir, Joan: The True Story of Britain’s Most Notorious Diamond Thief, and as depicted in the fictionalized 2024 TV series Joan.
She’d visit a jewelry store, posing as a wealthy US tourist, often in a fur coat. She’d flirt outrageously with the salesman, while carefully memorizing her target piece.
She’d later return with a cheap but convincing replica, fake a sneeze as she was viewing the piece for a second time, and swallow the genuine item. She’d then sterilize the stolen gems in a bowl of gin and sell them on to a fence.
Hannington, now aged 68, was sentenced to 30 months for possession of a stolen check book when she was 24,but she says she was never jailed for her diamond swallowing escapades. She does however suffer painful ulcers as a long-term consequence.
Jewelry from the collection of screen icon Elizabeth Taylor are to be sold at a Beverly Hills auction.
The highlight is a ruby, diamond, and gold necklace (pictured) with lion’s face design and matching earrings. Estimate $100,000 to $200,000.
There’s also a 1935 Art Deco emerald and diamond brooch – old mine-cut and European cut – mounted in platinum and gold, with an estimate of $20.000 to $30,000.
And a gold and diamond Star of David pendant necklace designed by Theo Fennell and marking her conversion to Judaism in 1959. Estimate $20,000 to $30,000.
They’ll be offered for sale at Bold Luxury: The Limelight Edit auction by Julien’s Auctions, on 27 March 27 at The Peninsula Beverly Hills, along with fashion and other items owned by Marilyn Monroe, Cher, Victoria Beckham and Amy Winehouse.
“Bold Luxury is not just an auction — it’s an invitation to step into the limelight and own a tangible piece of cultural history,” said Martin Nolan, co-founder and executive director of Julien’s Auctions.
Diamond Foundry, which has just opened a lab grown factory in Trujillo, western Spain, is facing an environmental backlash over claims it uses more water than the entire 8,500-population town where it is located.
Residents at a meeting earlier this month were told the new facility, built with $85m of European Union cash, was estimated to consume more than 730,000 cubic meters of water annually.
The huge facility will produce at least 4m carats a year and create 300 jobs. But environmental groups are concerned about the factory’s water usage, which is, they say “completely unsustainable”.
“There would be enough water for the diamonds but the population of Trujillo would have to buy jugs at the supermarket to drink, shower, cook, etc,” says an article in
Diamond Foundry, a Silicon Valley startup with Leonardo Dicaprio, star of the Blood Diamond movie, among its backers, is valued at $1.8bn.
“The water supply to Diamond Foundry is, once again, also in question, as it would cause serious supply problems for drinking water for the population of Trujillo and its surroundings,” according to the El Salto local news website.
It says the building is one of the first industrial projects in the world powered entirely by solar electricity and insists it holds the necessary permits to use reclaimed water from local treatment plants.
Sarine says cost reductions and efficiency improvements allowed it to reverse a $2.8m loss in 2023 into a $1.1m profit in 2024.
But the Israel-based diamond tech company said revenue dipped 8 per cent to $39.2m amid ongoing difficult market conditions – primarily weak demand in China and “continuing disruption from lab-grown diamonds”.
Sarine said it was recouping some of the costs invested in adapting its rough planning technologies for lab growns, and had also benefitted from opening a GCAL by Sarine lab in India, largely grading lab growns.
As party of its “aggressive business streamlining and cost cutting”, the company plans to relocate its manufacturing activities to India, its main market.
Looking to the future, it said demand for natural diamonds is likely to remain “constrained” throughout 2025, although markets for both natural and lab grown would become more distinct.
“It is our belief that diamond jewellery retailing will settle on a new equilibrium in the near term, with natural diamonds trending towards a significant market share especially in the bridal segment and LGD dominating the fashion jewellery segment.”
Botswana’s government signed on Tuesday a long-delayed diamond mining and sales agreement with Anglo American unit De Beers, the world’s leading diamond producer by value.
As part of the deal, Botswana’s share of the diamonds produced by Debswana, a 50-50 joint venture between the country’s government and De Beers, will increase from 25% to 50%. Botswana will receive 10 billion pula ($712 million) in development funding, in line with a provisional 10-year arrangement reached in 2023.
The agreement, in negotiations since 2018, also extends the mining licenses for Debswana until 2054. Previously, the licenses were set to expire in 2029.
The signing of the contract had stalled under former President Mokgweetsi Masisi but was prioritized by President Duma Boko, who took office last October.
Botswana, the world’s largest producer of rough diamonds by value, depends on the sector for the bulk of its national revenue. President Boko, however, has voiced concerns that the industry is not generating enough employment opportunities.
While Debswana’s diamond production accounts for 80% of Botswana’s exports, the country has struggled to diversify beyond mining. Despite a relatively high annual per capita income of $7,820 — exceeding that of oil-rich Gabon and South Africa, the continent’s biggest economy—job creation remains limited.
The deal comes at a crucial time for De Beers, as its parent company, Anglo American, considers spinning out the diamond business through a sale or initial public offering. Analysts warn that weak global diamond prices could complicate such a move.
Botswana remains integral to De Beers’ operations, supplying 70% of its annual rough diamonds. The government also holds a 15% stake in De Beers, underscoring the long-standing strategic partnership between the two parties.
Canada’s Lucara Diamond achieved record-breaking production in 2024, highlighted by the recovery of two exceptional stones at its prolific Karowe mine in Botswana.
The miner increased its processed ore to 2.9 million tonnes last year, up from 2.8 million tonnes in 2023. It also set a new milestone with the recovery of 807 “specials”—diamonds larger than 10.8 carats—compared to 602 in the previous year. These accounted for 7.6% of the total recovered carats, up from 5.3% in 2023.
The two most important diamonds recovered last year were the 2,488-carat Motswedi and the 1,094-carat Seriti diamonds, both unearthed at Karowe.
Motswedi, found in August, is the largest diamond recovered in the last century. Its name means “water spring” in the local Setswana language, symbolizing underground water surfacing to bring life and vitality.
The Seriti stone, unearthed in September, translates to “aura” or “presence”, reflecting cultural identity and legacy.
Lucara’s discoveries have continued this year, with the recovery of a1,476-carat non-gem diamond in January.
Revenue jump The company sold 399,215 carats in 2024, generating $203.9 million in revenue — an 18% increase from $172.4 million the previous year.
“Our world-class Karowe mine continues to set new benchmarks,” CEO William Lamb said in a news release. “The open-pit operations delivered yet another remarkable milestone with the recovery of our seventh 1,000+ carat diamond.”
Lamb also highlighted steady progress on Karowe’s underground expansion, with shaft sinking marking a major step forward. The project is expected to begin commercial production in early 2028.
Since it began operations, Karowe has yielded some of the world’s most remarkable diamonds, including the 1,758-carat Sewelô in 2019, the 1,109-carat Lesedi La Rona in 2015, and the 813-carat Constellation, also in 2015.
Karowe is also credited for having yielded Botswana’s largest fancy pink diamond to date, the Boitumelo.
The mine remains one of the world’s highest-margin diamond mines, producing an average of 300,000 high-value carats each year.
