Pink and yellow diamonds from two iconic Rio Tinto mines – Argyle and Diavik – have been brought together to create a unique ring.
It’s called Diavik Midnight Sun and has been valued at $1.24m.
An 18.08 carat fancy intense yellow oval diamond from Diavik, in sub-Arctic Canada, contrasts with an intricate setting of rare Argyle pink diamonds, from the now-closed mine in in the remote East Kimberley region of Western Australia, weighing 4.09 carats in total.
The yellow diamond was cut from a 36.75-ct rough gem, described as one of the finest large yellow diamonds uncovered at Diavik.
Rio Tinto’s general manager of sales and marketing for its diamonds business, Patrick Coppens said “This combination of a rare yellow Diavik diamond and Argyle Pink Diamonds, the rarest diamonds in the world, is a special moment in the history of Rio Tinto’s unique place in the natural fancy coloured diamond industry.
He paid tribute to luxury jeweler Musson for creating the ring. The Diavik Midnight Sun takes its inspiration from the exquisite natural phenomenon that occurs when the sun is seen at midnight in the Arctic, exhibiting beautiful golden and pink hues.
A rivière diamond necklace was the top seller at Christie’s Magnificent Jewels in Hong Kong on Monday, bringing in $5.9 million.
The sale price for the piece, which features 52 round brilliant-cut, D-flawless and internally flawless diamonds weighing a total of 104.84 carats, was within estimates. In total, the November 28 auction achieved $46.2 million, with 50% of the jewels on offer exceeding their high estimates, Christie’s said Monday.
The company sold 86% of available lots, or 82% by value, and drew global participation from 21 countries across three continents.
The auction also included a collection of jewels from Hong Kong actress Rosamund Kwan, which fetched a combined total of $11.1 million. The two leading lots from that sale saw heavily competitive bidding, lasting over 15 minutes, Christie’s noted. The top item in the group was a necklace featuring a pear brilliant-cut, 22.18-carat, D-color, VVS1-clarity diamond pendant with rubies and pink diamonds, which went for $2.1 million, within estimates.
Here are the rest of the top five:
A jadeite, diamond and sapphire necklace by Etcetera sold for $2.8 million against a presale estimate of $2.6 million to $3.8 million.
This cushion modified brilliant-cut, 60.79-carat, fancy-vivid-yellow, VS2-clarity diamond ring brought in $2.7 million, in the middle of its $2.3 million to $3.6 million presale range.
A round brilliant-cut, 19.61-carat, D-flawless, type IIa diamond ring exceeded its $1.7 million to $2.3 million presale estimate, bringing in $2.4 million.
This oval-cut, 5.32-carat Burmese pigeon’s blood ruby ring with pear-shaped diamonds by Cartier Paris achieved $2.1 million, within its expected range of $1.9 million to $2.3 million.
A 13.15 carat pink diamond will no longer be available at the upcoming Christie’s Magnificent Jewels auction in New York.
The emerald-cut, fancy vivid pink, VVS1 clarity stone, which carried a price estimate of $25 million to $35 million, was poised to be the December 6 sale’s showcase piece. Christie’s described the diamond as one of the largest of its kind to appear at auction.
“Christie’s confirms that the fancy vivid pink diamond ring has been withdrawn from sale in New York on December 6,” a spokesperson said. The company declined to comment further or provide a reason.
The item was scheduled to appear on display in Hong Kong on Friday. The removal was “very surprising,” said one colored diamond dealer in the municipality.
Colored diamonds have had a mixed season at auction. On November 8, the 18.18-carat Fortune Pink fetched CHF 28.4 million ($28.9 million) at Christie’s Geneva, toward the lower end of its presale estimate. The following day, a 5.53 carat diamond from the De Beers Exceptional Blue Collection failed to find a buyer at a Sotheby’s auction in the Swiss city.
With the 13.15 carat pink off the list, the top remaining item at the Magnificent Jewels sale is a pear modified brilliant cut, 31.62 carat, fancy blue diamond pendant with a price estimate of $10 million to $15 million.
Lucara Diamond Corp.’s sales dropped in the third quarter as the company supplied fewer large and expensive stones from its lucrative Karowe mine in Botswana.
Revenue fell 31% year on year to $49.9 million, while net profit slumped 86% to $1.8 million, Lucara reported Wednesday.
Sales of rough from Karowe declined 36% to $46.5 million, with volume down 15% at 99,301 carats and the average price falling 43% to $337 per carat. The remaining revenue came from sales of third-party goods on Lucara’s Clara online platform.
Management blamed a decrease in the number of high-value diamonds the company sold to HB Antwerp through the pair’s supply agreement. The Belgian manufacturer is contracted to buy all Karowe rough of 10.8 carats or more, with Lucara receiving a proportion of the final polished proceeds.
In the third quarter a year earlier, Lucara sold four pink diamonds and two white, type IIa stones — weighing 393.5 and 257.5 carats — to HB. As a result of the unfavorable comparison, revenue from the agreement plummeted 46% to $27.1 million.
“Despite the overall decrease in revenue recognized in [the third quarter], diamond-market fundamentals continued to support healthy prices as steady demand and some inventory shortages were reported,” Lucara said. Fluctuation in the availability of 10.8-carat production is expected, it added.
Output from Karowe slid 19% year on year to 78,879 carats for the quarter.
oronto-listed Mountain Province Diamonds will next week put on sale an “exceptional” coloured rough diamond, which it recovered from the Gahcho Kué mine, in Canada’s Northwest Territories.
The diamond, a 151.60 t octahedron of exceptional clarity, will be offered for sale alongside a selection of more than 90 individual special rough diamonds recovered from the company’s Canadian diamond mine.
The upcoming sale represents the biggest offering of +10.8 ct gem quality diamonds offered by the company to date.
“This important diamond represents a clear example of the Gahcho Kué mine’s ability to consistently recover high-quality gems of exceptionally large size. These gems are highly coveted by collectors around the globe not only for their beauty but increasingly, for their Canadian origin,” commented VP for diamond marketing ReidMackie.
Diamond is a naturally occurring rare mineral that is composed of pure elemental carbon. Due to the extremely rigid arrangement of the carbon atoms in a crystal structure, diamonds possess the maximum hardness and thermal productivity than any natural material. Diamonds are also in high demand as gemstones and as luxurious commodities. Despite having a reputation for being used in jewelry like rings and necklaces, 80% of mined diamonds are used for research and industrial purposes because of their toughness and shine.
The hardest substance known to man, diamonds, are frequently used to drill, grind, or cut other difficult materials. Initially, its reserves were only discovered in Africa and provided to the rest of the globe, but today, exploration and production of diamonds have also begun on other continents. Currently, Russia produces 30% of the world’s diamonds, and approximately 39.12 million carats of diamonds were produced in Russia in 2021, making it by far the greatest diamond-mining nation in the world. With a production of 22.9 and 17.6 million carats of diamonds, respectively, Botswana and Canada are placed in second and third place, followed by the Democratic Republic of the Congo and South Africa.
1. Russia (39.12 Million Carats)

Russia presently leads the world in diamond output after it began mining in 1947. Regarding volume, it is also the top exporter of rough diamonds worldwide. ALROSA is Russia’s largest diamond miner, maintaining a virtual monopoly over the sector and producing over 90% of the nation’s annual output. Russia houses some of the world’s greatest mines and diamond reserves (some of which have not yet been explored), including Udachny, Grib, and Aikhal. It was revealed in 2014 that Alrosa intends to expand the Udachny mine into a 5 million carat per year project, making it the most significant diamond mine in both Russia and the entire globe. Alrosa first used Udachny in 1971, and during the following 43 years, it has helped the company make over $80 billion. Alrosa should be able to keep its position as the world’s biggest diamond producer by volume for the foreseeable future due to Udachny’s figures.
2. Botswana (22.88 Million Carats)

A significant diamond mine was found in 1966, the year Botswana declared its independence from Britain, in a rural region called Orapa, about 250 miles from the nation’s capital of Gaborone. De Beers, the firm that discovered the mine, was and still is the world’s largest supplier of “rough stones.” The two most significant of the seven mines in the country are Orapa and Jwaneng. Despite ranking second in terms of volume, Botswana tops the list of the world’s top producers of diamonds. Botswana, which was one of the world’s 25 poorest nations, has achieved upper-middle income status due to the revenue from diamonds. The nation is currently vying for a more significant position in the sector as the No. 1 player Russia faces condemnation from around the world for its invasion of Ukraine.
3. Canada (17.62 Million Carats)

The Northwest Territories, which were once used as hunting grounds, are now used mainly for large-scale resource extraction, including diamond mining. Diamonds weren’t found by non-natives until 1991, specifically by two geologists named Chuck Fipke and Stewart Blusson. The first diamond mine in the Northwest Territories, known as Ekati, opened in 1998 because of this finding. The Arctic Canadian Diamond Company presently oversees the operation of Ekati, which is a responsible steward of the environment and a significant source of high-quality employment and money for the area. Most of Canada’s diamonds are mined in the Northwest Territories, which comprise about 40% of the total geographical area. There are currently four working diamond mines in Canada, three in the NWT – the Ekati, Diavik, and Gahcho Kué mines – and the Renard diamond mine in Quebec.
4. Democratic Republic Of The Congo (14.09 Million Carats)
The Democratic Republic of the Congo is the country that turned South Africa’s diamond industry profitable. Miniere de Bakwange (MIBA), a joint venture between the Belgian business Sibeka and the DRC government, which controls 80% of the company, is the only commercial diamond producer in the DRC. Although ongoing political unrest has caused production to fall recently, the DRC has the capacity to produce more diamonds. Only a tiny area has been examined, and mining has only ever been done on a small basis. Most of the DRC’s output is mined by the informal sector rather than mining companies. De Beers markets about one-third of Sibeka’s production and holds a 20% stake in the company.
5. South Africa (9.72 Million Carats)

Almost all the modern diamond trade originates in South Africa. The earliest diamonds found in South Africa were alluvial diamonds. Diamonds were initially discovered in yellow earth in 1869, and then later below ground in hard rock called blue ground near and in what would become Kimberley in the Northern Cape, the diamond center of the world. Later, the blue rock was given the mining town’s name: kimberlite. One of the country’s biggest diamond deposits is located in the South African province of Gauteng. As the government and miners continue to find significant diamond resources and pipelines, the demand for diamonds in South Africa is anticipated to rise.
One can therefore expect the global diamond industry to keep expanding and displaying a bright future as long as economic prosperity continues to improve and as long as there are still diamond reserves that have not yet been mined.
India, which cuts or polishes about 90% of the diamonds sold in the world, is ramping up sales of laboratory-made gems as demand from the US surges and they become more accepted in other markets.
Exports of polished lab-grown diamonds may double in the current financial year started April 1 from $1.3 billion in the prior year, Vipul Shah, vice chairman of the Gem & Jewellery Export Promotion Council, said in an interview. “We have a huge potential to grow exports to $7 billion-$8 billion in the next few years on the back of US demand and acceptability in the UK and Australia,” he said.
“It is going to be treated as a fashionable jewelry, which is affordable to the youngsters, and that’s the way the market is going to shift,” Shah said.
Diamonds grown in labs represent a small portion of the market currently — India shipped nearly $24 billion of polished diamonds mined naturally last year. Still, the much cheaper variety has been growing its share as it has the same physical characteristics and chemical makeup as mined stones, with experts needing a machine to distinguish between synthesized and mined gems.
Lab-made diamonds are developed from a carbon seed placed in a microwave chamber and superheated into a glowing plasma ball. The process creates particles that crystallize into diamonds in weeks.
Exports of polished lab-grown diamonds from India jumped about 70% in the April-July period to $622.7 million, while those of cut and polished mined diamonds fell around 3% to $8.2 billion during the same period, GJEPC data showed.
One advantage of the man-made gem is that it has a tracking system that helps monitor the supply chain and maintain consumer confidence in the gems.
“Commercial gem-quality earth-mined diamonds are being replaced completely by lab-grown diamonds,” said Ritesh Shah, director at ALTR, one of the first global lab-grown brands to start business in India. The product’s affordability, low carbon-footprint, size and fine quality offer a big draw for buyers, with the US the front-runner in the shift in consumer behavior, he said.
From a handful of companies growing diamonds in labs in the mid-2000s, there are now about 25 such growers in India, he said. The country contributes about 15% of the global production of lab-grown diamonds, according to the GJEPC.
Signet Jewelers has signed a deal to acquire online retailer Blue Nile for $360 million in cash.
The purchase will boost Signet’s bridal, “accessible luxury” and digital businesses, while expanding the group’s consumer base, the US retail chain said Tuesday. The company expects to complete the transaction in the third fiscal quarter, which runs until late October. Either side can pull out if the deal hasn’t closed by November 3, 2022.
“Blue Nile brings an attractive customer demographic that is younger, more affluent, and ethnically diverse, which will broaden our customer-acquisition funnel,” Signet added.
The announcement comes around two months after Blue Nile revealed plans for a stock-market flotation via a merger with Mudrick Capital Acquisition Corporation II, a special-purpose acquisition company (SPAC). The proposed deal valued Blue Nile at $873 million. Mudrick was not immediately available for comment on how that transaction progressed. The current owners are Bain Capital Private Equity and Bow Street, which acquired the e-commerce jeweler for around $500 million in 2017.
Blue Nile’s sales exceeded $500 million in 2021, according to Signet, which has stated its intention to reach total annual revenues of $9 billion in the coming years. Last October, it agreed to acquire Diamonds Direct USA for $490 million; in 2017, it bought diamond retail website James Allen for $328 million.
“By joining Signet, we will extend our premium brand and fine-jewelry offering to millions of new customers while bringing new capabilities to our leading e-commerce business that will drive additional growth opportunities for Blue Nile,” said Blue Nile CEO Sean Kell.
Meanwhile, Signet has reduced its sales guidance for the second quarter, which ended in late July, estimating revenue of $1.75 billion compared with an earlier forecast of $1.79 billion to $1.82 billion. Management cited “heightened pressure on consumers’ discretionary spending and increased macroeconomic headwinds.”
“We saw sales soften in July as our customers have been increasingly impacted by rapid inflation, so we’re revising guidance to align with these trends,” said Signet CEO Gina Drosos. The new outlook for the quarter still translates to a sales increase of around 25% compared with the equivalent period of 2019, before the Covid-19 pandemic, the executive noted.
Diamonds recovered at the Star-Orion South project.
There are few things that are more alluring and exciting than a diamond — but one of them is a significant new diamond discovery. Now those are truly rare.
In Canada, we haven’t had a significant diamond discovery for years — and the current lack of spending on exploration makes one less likely to happen in the future.
Globally, exploration for diamonds has nearly ground to a halt. In Canada last year, coal exploration attracted more spending than diamond exploration ($61 million vs. $50 million), which fell 21% from the previous year, hitting a 20-year low.
Adding to this downward momentum, in June, Rio Tinto suddenly pressed pause on its 75%-owned Fort à la Corne (Star-Orion South) diamond joint venture in Saskatchewan. After pouring more than $180 million over the past six years into a bulk-sampling program and other work to evaluate the project, Rio Tinto told JV partner Star Diamond it would not be spending more money this year “beyond what is necessary for care and maintenance.” Star Diamond, which holds 25% of the large but low-grade project, said that Rio also advised that it “intends to conduct a near-term review of its alternatives regarding the project, including its potential exit.”
It’s not clear yet what Rio Tinto will ultimately decide to do. But further investment, rather than pulling back, would have given the sector a much-needed shot in the arm. And the company, which saw its Argyle mine in Australia close in late 2020, certainly needs to replace that production and would be motivated to make the project work, if possible.
While the diamond trade and diamond prices were devastated by the pandemic, prices have made a strong comeback (in part benefiting from uneven efforts globally to avoid purchasing diamonds mined by Russia’s Alrosa). De Beers reported a 58% rise in its average selling price to US$213 per carat for rough diamonds in the first half of the year, and its rough price index rose 28% compared to the same period of 2021.
That’s not likely to help revive exploration immediately, however.
The fact is that there have been too many surprises in diamond development around the world, which have shattered investor confidence.
De Beers’ revenue rose 24% in the first half of 2022, but the miner gave a more somber outlook for the rest of the year.
“We can only have strong rough sales if that’s also coupled by what’s going on on the polished side,” De Beers chief financial officer Sarah Kuijlaars told Rapaport News on Thursday. “The polished position was very strong in the beginning of the year, but it has leveled off. We have much more caution about the next six months than we’ve had for the previous six months.”
Revenue jumped to $3.6 billion in the first half as strong consumer spending during the 2021 holiday season led to intense restocking in early 2022, parent company Anglo American reported the same day. Underlying earnings gained 84% to $491 million.
Rough sales grew 27% to $3.3 billion from five sights during the period. The remaining revenue relates to other businesses such as the company’s consumer brands and industrial-diamond business.
The miner’s rough-price index, which measures like-for-like prices, rose 28% compared with the same period of 2021. The average selling price for rough surged 58% to $213 per carat, reflecting the market upturn and a shift in the product mix to higher-value goods. Sales volume fell 20% to 15.3 million carats.
The higher average price resulted from the introduction of the new Benguela Gem mining vessel off the Namibian coast, which enabled the extraction of more lucrative stones, Kuijlaars explained. In addition, production at the Venetia deposit in South Africa was focused on the final cut of the open-pit mine, which has a relatively high grade — the number of carats per tonne of ore — and high quality, the executive added.
De Beers’ results painted a complex picture of the market. Last week, the company raised its production plan for the full year in response to strong demand, predicting output of 32 million to 34 million carats. It also noted that the sanctions and boycotts targeting Russian diamonds, as well as growing interest in provenance initiatives, would “underpin” demand for its goods. The sixth sales cycle of the year, which took place earlier this month, brought in proceeds of $630 million — 23% higher than for the equivalent period a year ago.
However, inflation in the US and lockdowns in China have created concerns across the industry.
“This time last year, our operation was coming out of Covid-19 [during which output slumped],” Kuijlaars pointed out. “To stabilize our production has been really important, and that strong production gives us confidence for the full year. That’s our part in delivering reliable supply. As we sell that through, we are very alert to signs of any slowdown in the remaining four sights of the year.”
