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.
London, England, Westminster Magistrates Court in London
A cleaner has appeared in court in London, charged with stealing diamonds, watches and jewelry worth $1.3m (£1m) from her employer, Princess Firyal of Jordan.
Maria Taborda Henao, aged 69, from Colombia, is accused of stealing the items between February and November 2020 and of selling them through an auction house.
The case against her at Westminster Magistrates’ Court (pictured) was adjourned on Monday (10 March) because there wasn’t a Spanish interpreter in court.
Princess Firyal, aged 80, is a noted humanitarian and philanthropist, and has served as a UNESCO Goodwill Ambassador since 1992. She is the former wife of Prince Muhammad bin Talal, the second son of the late King Talal of Jordan.
The thefts of diamond rings, bracelets, watches and earrings allegedly took place at the princess’s $7.5m home in the exclusive Belgravia area of London. The case will resume next month.
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.
The Russian government could buy more rough diamonds from the state-run miner Alrosa, as it faces ongoing G7 sanctions and weak global demand.
The Finance Ministry says it will assess the situation after seeing second quarter results.
Alrosa last week reported a 77 per cent slump in profits for 2024 (down to $223m) and has said it could suspend some less profitable activities and lay off some of its 35,000 workers.
“As we have already said, it is possible that Gokhran will buy some of the stones, said Deputy Finance Minister Alexey Moiseyev, according to a report by the privately-run Interfax news agency.
“At this stage, we are still observing the market dynamics, indeed, it is quite weak, but not much time has passed. In principle, the first quarter is rarely good.”
Alrosa has previously offloaded excess inventory to Gokhran, the Russian State Precious Metals and Gemstones Repository in times of weak demand.
During the financial crisis of 2009 Gokhran bought up $1bn of Alrosa’s diamonds. And it sold back millions of carats in 2022, when a surge in post-lockdown demand outstripped the miner’s production capacities.
Last November it said it would be selling a batch of rough diamonds, including its largest recovery in a decade – an irregular-shaped diamond weighing 390.7 carats
Sales of watches and jewelry in the US dipped in January, for the first time in well over a year. They were 3.0 per cent less than the previous January, according to the latest figures from the US Department of Commerce.
In addition, revisions to November and December sales figures now show slower growth than originally reported.
Figures based on actual through-the-till transactions, rather than estimates, put sales at +2.6 per cent and +1.5 per cent respectively, rather than the revised figures of +3.0 per cent and +4.0 per cent.
Sales of watches and jewelry had been in positive growth since October 2023, and they peaked last September and October at around 10 per cent. Prior to that they’d been in overall decline since October 2022.
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.
The 1,094-carat Seriti diamond recovered last September from Lucara’s Karowe mine, in Botswana, is now in Belgium, where it will be cut by HB Antwerp as part of an ongoing partnership.
HB, founded in 2020, cut the 1,758-carat Sewelo diamond and the 549-carat Sethunya diamond – both of which were recovered at Karowe and both of which were bought by Louis Vuitton.
Exact prices were not disclosed, although Lucara did say last month that the Sethunya and the 1,080 carat Eva Star, sold for a combined $54m. HB gave no details of a buyer for the Seriti.
Seriti is the world’s sixth largest rough diamond, and the sixth +1,000-ct diamond recovered at Karowe.
HB says it will use “groundbreaking technology, traceability, and expertise to unlock the full brilliance of nature’s most exceptional creations”.
That includes its proprietary Hyperloupe technologies, designed specifically for large (up to 6,000 carats) and complex diamonds.
HB has a 10-year contract with Lucara to cut all its +10.8-cts stones. They account for around 70 per cent of the miner’s revenue.
Rio Tinto reported a $127m loss for 2024 from its Diavik diamond mine, in Canada, as weak market conditions led to “fixed cost inefficiencies”.
That compares with underlying earnings of $26m in 2023. Rio Tinto’s diamond sector generated $297m of revenue during the year, a 37 per cent drop on $444m the previous year.
The British-Australian multinational emailed over 1,300 employees last September, offering them voluntary separations to reduce operating costs as it prepares to close the mine next year.
In its Full Year Results 2024 the company noted the tragic loss of four Diavik workers and two air crew when a plane headed for the mine crashed last January.
Rio Tinto reported a 17 per cent drop in production, from 3.3m carats in 2023 to 3.4m carats in 2024.
The company acquired full ownership of the mine in November 2021 after it bought out a 40 per cent stake from Dominion Diamond Mines.
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.
