 Lucapa Diamond Company has recovered a 160-carat, high-quality rough from its Lulo mine in Angola, the sixth-largest stone the deposit has yielded.

The company found the type IIa diamond at the same alluvial mining block from which it unearthed a 170-carat pink — the Lulo Rose — in July, Lucapa said last week. The new addition marks the 28th diamond over 100 carats from Lulo.

Recently, Lucapa transitioned to mining rough from the lezirias, or flood plain area, of the site, which has led to the recovery of larger diamonds, it said. In the past two months, the miner has found more than 100 special stones — those weighing over 10.8 carats — at the deposit, including four type IIa rough diamonds weighing 99, 81, 74 and 66 carats.

11.15-Carat Internally Flawless Pink Diamond Could Fetch $21 Million

 11.15-Carat Internally Flawless Pink Diamond Could Fetch $21 Million

11.5-carat Williamson Pink Star diamond

The second largest internally flawless fancy vivid pink diamond to ever appear at auction was unveiled Wednesday in London by Sotheby’s. The 11.15-carat Williamson Pink Star will be sold in a single-lot auction in Hong Kong on October 5. Its estimate is $21 million.

The auction house says it has the potential to set a new per carat price record for a fancy vivid pink diamond.

“We do have the confidence that it will find a great collector and have the interest of multiple parties,” Wenhao Yu, chairman of Jewellery and Watches at Sotheby’s Asia, told Forbes on Tuesday. “It has the potential to reach a very strong price.”

He adds, “This diamond truly checks all the boxes. It has the best qualities you can have in a pink diamond.”

The current price per carat auction record for a fancy vivid pink diamond is $2,656,909 for the 18.96-carat Winston Pink Legacy, sold in 2018 by Christie’s Geneva. The largest internally flawless, fancy vivid pink diamond offered at auction is the 59.60-carat CTF Pink Star. It was sold by Sotheby’s Hong Kong in 2017 for $71.2 million, a world record for any gem or jewel sold at auction.

Yu compares the Williamson Pink Star to an exceptional work of art.

“We timed this lot to be offered between Sotheby’s modern and contemporary art auctions. That’s because instead of offering just another important diamond, we view this diamond as a work of art from mother earth and a wonder of nature,” Yu says. “It’s comparable to a Monet or a Picasso and is even more rare.”

The Williamson mine is one of the oldest operating diamond mines in the world, famous for producing what is described as “bubblegum” pink diamonds, according to the auction house. One of the best-known diamonds from the mine is the 23.6-carat Williamson Pink Diamond fashioned into a brooch by Cartier and owned by Queen Elizabeth II.

“We wanted to relate the important provenance of the Williamson mine when naming the diamond,” Yu says. “The unique saturated pink color is one of the important qualities of diamonds from this mine. It is an honor for us that after so many decades another important pink diamond comes from the Williamson mine and we can offer it at auction.”

The cushion-shaped diamond was crafted from a 32.32-carat rough diamond by Diacore, a diamond manufacturer that specializes in crafting rare, exceptional fancy-colored diamonds. The company purchased the gem in late 2021 for $13.8 million. Yu says crafting the diamond is just as important as discovering it, and Diacore is one of the few companies in the world capable of cutting and polishing such an important gem.

“Not every rough can yield a diamond of this high quality so we should also give credit to Diacore,” he says. “They really made cutting and polishing into an art. They are very skilled and experienced with the best technology and a lot of courage. It’s rare to have a vivid pink color. It’s rarer when it’s over 10 carats and even more rare if it’s internally flawless. It’s luck to find this kind of diamond that was formed underground for millions of years, and it takes a great amount of art and creativity to fashion it into a gorgeous stone with so many exceptional qualities.”

Pink diamonds are among the rarest colors to occur naturally in diamonds. Of all the diamonds submitted to the Gemological Institute of America (which analyzes and grades diamonds), fewer than 3% are classified as colored diamonds, and fewer than 5% of those are considered predominantly pink.

The Argyle Mine in Australia, before it was retired in 2020 after exhausting its supply of gem-quality diamonds, produced more than 90% of the world’s pink diamonds. The absence of pink diamonds from this mine makes important pink diamonds like the one being offered even more rare, Yu says.

“Pink diamonds are still growing in demand in the market, and this now makes the Williamson Pink Star even more sought after,” he says.

The diamond is being presented in an 18k gold ring flanked by trapeze-cut diamonds and embellished with brilliant-cut diamonds.

London is the first stop where the diamond will be viewed by the public. It will then travel to Dubai, Singapore and Taipei before the final viewing and sale in Hong Kong.

Heritage Auctions has unveiled a 1.21-carat, fancy-orangey-red diamond that will go under the hammer at its Fall Fine Jewelry Signature auction on September 29.

“This gem is one of only a few diamonds to display enough saturation and intensity to be graded as a true red,” said Jill Burgum, Heritage Auctions’ executive director of fine jewelry. “Adding to the allure, the cause of a red diamond’s color remains a mystery to scientists, making this stone even more of a marvel.”

The stone has a presale estimate of $100,000 to $150,000.

Other notable diamonds included in the sale are a 17.63-carat, fancy-intense-yellow diamond ring from the estate of Dallas philanthropist Mary Anne Sammons Cree, which is expected to fetch $300,000 to $400,000. More than 125 jewels from Cree’s collection are up for sale, with the proceeds going to the Communities Foundation of Texas as well as Dallas-area nonprofits.

 The World’s Most Expensive Apple Watch Case

Apple watch Golden Concept
Apple watch Golden Concept

Apple Watches can do everything. You can use one to track your blood pressure or unlock your car. You can use it to pay when you’re shopping or even to order a pizza. But as fans of traditional mechanical watches, we have to ask – where’s the elegance? Where’s the extravagance? You can’t flex with an Apple Watch the way you can with a Rolex Daytona and there’s no smartwatch that catches the eye like James Bond’s Omega Seamaster. Well, that was until the Swedish luxury tech accessory brand Golden Concept announced its outrageous new diamond-encrusted Apple Watch case – the most expensive in the world.

Golden Concept

You read that correctly, these are the first and only Apple Watch cases decorated with real diamonds, and if you have $15,000 spare you can grab one. But be quick as there are only 7 of these spectacular cases available, each housing 443 diamonds. Based in Stockholm, Golden Concept is a world leader when it comes to crafting exclusive and ultra-high-quality cases for Apple products, but this new release had even its biggest fans doing a double take.

So what’s all the fuss about? Quite simply, it’s the diamonds. For a start, each watch case has nearly five hundred of them and they take a week to set and hand finish. And these are exceptional E colour grade diamonds – this is the second-highest colour grade, meaning they have exceptional clarity and colourlessness. They are set into a case carved from a single block of solid titanium, a metal both stronger and lighter than the stainless steel more commonly used for watch cases.

The result is a stunning design and the select buyers can have a case created for an Apple Watch 7 or opt to preorder one for the upcoming Series 8. In addition, each watch can be personalized with an engraving on the case back and, in a nice touch, the Golden Concept watches also come with a customised strap fashioned from high-performance fluoroelastomer. This is a famously durable material that is also resistant to changing temperatures making it ideal for sports use.

Yes, the price of the Diamond Edition case is insane, but we’re sure that buyers are going to love the opulence regardless. These Apple watches are neither sensible nor utilitarian. Instead, they’re over the top and excessive – ideal if you like your tech to be something to flaunt.

World's Top 5 Diamond-Producing Countries

Russian diamonds
                   ALROSA Russian diamonds

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.

US demand to lift India’s lab-made diamond exports to $8 billion


Lab-grown diamonds
                       Lab-grown diamonds

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.
