What is the difference between a natural mined diamond and a laboratory grown diamond?

*Laboratory grown rough diamond type 2A carbon crystal.*

The main difference between a natural mined diamond and a laboratory grown diamond is their origin. Natural diamonds are formed deep within the Earth’s mantle under extreme heat and pressure over millions of years, while laboratory grown diamonds are created in a controlled environment in a laboratory setting.
Some other differences between natural mined diamonds and laboratory grown diamonds include:

Cost: Laboratory grown diamonds are generally less expensive than natural mined diamonds, as they don’t require expensive mining and extraction processes.
Clarity: Laboratory grown diamonds are generally more consistent in terms of their clarity, as they are grown under controlled conditions. Natural mined diamonds can have inclusions or blemishes, which can affect their clarity and value.
Size and Colour: Laboratory grown diamonds can be grown to larger sizes and in a wider range of colours, which may not be as easily available in natural mined diamonds.
Environmental impact: The environmental impact of laboratory grown diamonds is generally considered to be lower than that of natural mined diamonds, as mining can have a significant impact on the environment.
Rarity and Value: Natural mined diamonds are still considered more rare and valuable than laboratory grown diamonds, due to their long history and cultural significance.
Ultimately, whether someone chooses a natural mined diamond or a laboratory grown diamond may depend on their personal preferences and priorities, such as environmental concerns, budget, or the desire for a natural, unique stone.

It is worth noting that both natural mined diamonds and laboratory grown diamonds are chemically and physically identical, and both can be certified and graded by independent gemmological laboratories based on the same criteria.

De Beers Lifts Prices of Its Smallest Rough Diamonds

De Beers has increased prices of small rough diamonds for the second consecutive sight as a combination of demand and supply factors continue to create a hot market for the category.

Prices for tiny stones rose by around 10% on average at this week’s trading session, with sharper advances in certain segments, customers and insiders estimated Monday. The changes were mainly for minus-7 sieve sizes, which weigh about 0.03 carats, across a range of qualities. De Beers was unavailable for comment.

The February sale runs this week from Monday to Friday in Gaborone, Botswana.

Rough under 0.75 carats became a sought-after asset in the second half of 2022 as melee demand from luxury brands strengthened and Indian manufacturers needed cheaper material to fill factories amid thin profit margins. In addition, Western sanctions on Russian diamonds created a mixture of real and perceived shortages in those sizes, for which Alrosa is the biggest supplier. The trade is watching for potential further restrictions as the one-year anniversary of Russia’s invasion of Ukraine approaches.

“Are people preempting what the [new] measures might be on Russia? [The strong market] might have to do with that,” a rough-market participant told Rapaport News on condition of anonymity.

Last year, De Beers made only modest increases in the prices of smalls, even when the segment saw robust demand, a sightholder explained on condition of anonymity. The miner raised prices at last month’s sight by approximately 10% — alongside decreases in the slower, larger goods.

The fresh hikes caught many dealers by surprise, as they were expecting De Beers to monitor the Chinese recovery before making further price adjustments.

G-7 and EU looking at ways to track and trace Russian diamonds

Group of Seven nations and the European Union are discussing ways to track Russian diamonds across borders, a move that could pave the way for restrictions on their trade in future, according to people familiar with the matter.

Previous EU attempts to sanction Russian gems have run into resistance from importer nations such as Belgium who argue that the effort would be futile because transactions will simply shift elsewhere without a mechanism to trace precious stones.

A diamond’s origin is clear at the start of the supply chain when it is issued a certificate under the Kimberley Process, which was designed to end the sale of so-called blood diamonds that financed wars. But after that they can become difficult to track.

Cut and polished stones are often intermingled at trading houses and the original certificate will be replaced with “mixed origin” documentation, making it near-impossible to keep track of where Russian diamonds are eventually sold.

The US has sanctioned the Russian mining giant, Alrosa PJSC, which accounts for about a third of the $80 billion global trade in rough diamonds. But the measures have had limited impact as much of the trade flows through other markets such as India.

The people with knowledge of the G-7 and EU discussions said a solution is not imminent, because tracing polished diamonds in a global market is extremely complicated. Still, two of the people said the G-7 could issue a statement on the matter as early as next week as part of the effort to maintain pressure on Russia as its war in Ukraine approaches the one-year mark.

Botswana, De Beers row over diamond profits

Botswana’s President Mokgweetsi Masisi warned Sunday that his country could sever ties with South African diamond giant De Beers if talks to renegotiate a sales agreement prove unfavorable for his country.

The 2011 sales agreement governing the terms of marketing diamonds produced by Debswana – a 50-50 joint venture between the government and De Beers – expired in 2021.

It has been extended by the parties, who cited the coronavirus outbreak as the reason for the delay in concluding negotiations, and will end on June 30, 2023.

Speaking at a rally of his ruling Botswana Democratic Party (BDP) in his home village of Moshupa, about 65 kilometers from the capital Gaborone, Masisi warned, “If we don’t reach a win-win situation, each side will have to pack up and go home.”

Under the 2011 agreement, the mining company De Beers received 90% of the rough diamonds produced while Botswana, Africa’s largest diamond producer, received 10%. In 2020, Botswana’s share was increased to 25%.

In 2020, Botswana’s share was increased to 25%.

Today, “we got a glimpse of how the diamond market works, and we found out that we received less than we should have,” said Mr. Masisi, who spoke in both English and the local language, Tswana.

“We also found out that our diamonds are bringing in a lot of profit and that the (2011) agreement had not been favorable to us,” he added, before warning: “We want a bigger share of our diamonds. Business cannot continue as before.

Botswana Has the World’s Two Richest Diamond Mines

A new list names the Jwaneng diamond mine, in Botswana, as the world’s richest diamond mine.

A new list by miningintelligence.com, quoted by IDEX Online, names the Jwaneng diamond mine, in Botswana, as the world’s richest diamond mine for the first three quarters of 2022. Jwaneng produced 10.3 million carats in 2022.

Orapa, also in Botswana, came second with 8 million carats. Both Jwaneng and Orapa are operated by Debswana, a partnership between De Beers and the government of Botswana. Jwaneng and Orapa were also listed as the two highest value diamond mines in the world, estimated at $1.25 billion and $976 million respectively, “based on average historic annualized prices of $121.5 per carat,” according to the report.

Alrrosa’s Udachny mine came third. Although Alrosa has not published production figures since the war with Ukraine, miningintelligence.com bases its conclusion on the mine’s 2021 production of 4.6 million carats. Fourth comes the Venetia mine in South Africa 4.6m carats, operated by De Beers. In fifth is Nyurba, in Russia, with 3.6 million carats, based on 2021 numbers.

Tanzania Reports Record $63 Million in Diamond Exports Despite Williamson Mines Closure

The Bank of Tanzania announced that the country’s diamond exports increased significantly to $63.1 million (USD) in value by November 2022. This is more than seven times of the $8.4 million export value that was recorded in the year-over year analysis since November 2021.

The good performance of the company has been attributed to the country’s diamond producer Williamson Mines which has temporarily shut down operations due to a recent tailings breach on November 7, 2022. The mine is an open pit operation located on the 146-hectare Mwadui kimberlite pipe, which is one of the world’s largest economic kimberlites.

The company belongs to the parent company Petra Diamonds, which owns 75 percent of the company, and the Tanzanian government owns the remainder. According to Petra’s official statement, production at the Williamson mine will resume in the 2024 fiscal year.

Tiffany Buys Some of a Legendary Diamond Mine’s Last Finds

The new Tiffany Collection comprises 35 gems, including an unusual red stone, from the Argyle Diamond Mine in Australia.

About a year ago, a representative of the Argyle Diamond Mine — a site in Western Australia that was the pre-eminent source of pink diamonds until it closed in 2020 — approached Tiffany & Company’s chief gemologist with an unusual offer: the chance to purchase a collection of diamonds that were among the last stones taken from the mine.

The decision, Tiffany executives said, didn’t require much consideration.

“We had to do it,” Anthony Ledru, the brand’s president and chief executive, said in his bright office in New York’s Flatiron district. “It’s perfect with what we stand for.”

The purchase, which was finalized several months ago, involved 35 diamonds of various shades: pink, almost purple and even one red gem, an especially unusual color for a diamond. The gems, which had already been cut in various styles, “checked off all of those boxes: rarity, scarcity and beauty,” said Victoria Reynolds, Tiffany’s chief gemologist.

But the stones are small, ranging from 0.35 carats to 1.52 carats, considerably more petite than the statement-size gemstones frequently used in engagement rings and solitaire necklaces.

“These are small, there’s no doubt,” Ms. Reynolds said, “but for connoisseurs, collectors who understand how rare these are, it’s incredibly appealing.”

How much did the jeweler pay for what it now calls the Tiffany Collection? Mr. Ledru wouldn’t disclose the sum, but said it was “probably not enough compared to what it’s going to become in the next five, 10 years.” (He did note that it was Tiffany’s largest single purchase of 2022.)

Exactly how the diamonds will be used in jewelry hasn’t been decided, although Mr. Ledru said it was likely that they all would be used in one-of-a-kind designs. In the meantime, the diamonds are being shown to select clients in New York City and, next month, in Doha, the capital of Qatar.

The eventual prices are sure to be high. “You pay a premium for anything that says ‘Argyle pink diamond,’” said Renée Newman, an independent gemologist and author based in Los Angeles.

Alrosa Finds 2 Huge Diamonds at Udachnaya on the Same Day

Two large high-quality diamonds – each larger than 50 carats – were unearthed in Yakutia on December 2, 2022, Bankers Day, “when Russian bankers celebrated their professional holiday,” according to Rough & Polished.

The two stones were extracted at Processing Plant No. 12 from the ore mined at the Udachnaya diamond pipe. One weighs over 67 carats, while the second diamond, a type IIa, weighs more than 52 carats,

Dmitry Amelkin, Alrosa’s Strategy Director, commented: “Finding two of these rare gem-quality diamonds on one and the same day is a unique coincidence. It is symbolic that this happened precisely on the Udachnaya diamond pipe, which has been accompanied by good luck since its discovery.

De Beers Slashes Prices of Larger Rough Diamonds

De Beers has made sharp price changes at this week’s sight, implementing deep reductions in larger goods and increases for smaller stones.

Prices fell by as much as 10% in 2-carat rough and above, with lower-quality items seeing the most significant drops, sources told Rapaport News Monday on condition of anonymity. Prices of diamonds under 0.75 carats rose by similar percentages, reflecting a market split that has persisted since late last year, insiders said. Sizes in between saw more modest declines.

“There have been quite wild increases and decreases,” one source said. “Not to say that they’re not justified, but it’s interesting that they’ve done that.”

De Beers declined to comment.

The adjustments follow months of sluggishness in larger, lower-quality rough as Chinese demand slumped during the country’s Covid-19 outbreaks and inflation dented mid-market US spending. Stones in the 3-grainer category and below have remained relatively strong due to steady sales of polished melee and Indian manufacturers’ efforts to fill factories with cheaper material.

De Beers kept its prices firm throughout 2022 despite the weakness in the larger categories, which constitute a significant proportion of its sales. This impacted profit margins at cutting firms, many of which perceived the miner’s rough to be expensive, insiders explained.

“These are the prices [at] which they should have been selling since October,” a sightholder commented. “It’s aligning with reality [rather than] reflecting a relatively poor end of year.”

De Beers is known for its reluctance to reduce prices during downturns, as was the case during the Covid-19 crisis. Now, as then, it has waited for a slight improvement in trading before taking action. China’s reopening has boosted sentiment, while the recent US holiday period was satisfactory, albeit slower than 2021’s record season.

The first sight of 2023, which runs Monday to Friday, comes amid uncertainty about the global economic situation, the Russia-Ukraine crisis, and the prospects for the Chinese New Year, which occurs on January 22.

It’s also a time of transition at De Beers, which is welcoming a new CEO, Al Cook, to succeed Bruce Cleaver on February 20 and is in the middle of negotiations with the Botswana government over an updated sales deal.

“Generally, things are a bit better than they were four or five months back, but that is because of low [polished] production, not because of an improvement of the market,” a manufacturing executive commented. “So the challenges remain.”

Sarine to Buy Majority Stake in Grading Lab GCAL

Sarine Technologies has agreed to acquire a majority share in New York-based Gem Certification and Assurance Lab (GCAL) amid a push to expand in the American market.

“At the beginning of last year, we started ramping up our activities in the US,” Sarine CEO David Block told Rapaport News on Thursday. “Due to that, the discussions with regard to this [deal] ramped up along with our involvement in the US market. This [deal] should be quite a significant jump in the scope of our business in the US.”

Israel-based Sarine has signed a nonbinding memorandum of understanding (MoU) to purchase the stake for an all-cash consideration, it announced in a statement on Wednesday. The parties plan to reach a final agreement in a few months once due diligence is complete, Block said. The companies have not disclosed the sale price or the size of the share.

GCAL will continue to offer its customers the same products and services as before the deal, and its executives will remain in charge, Sarine said.

However, while currently operating out of a single location in New York, GCAL will be able to implement Sarine’s e-Grading — an automated grading service using artificial intelligence (AI) — to develop the lab’s capabilities across the US and globally. The companies will begin integrating their technology and services even before the deal closes, Block explained. Sarine will continue to offer its services independently outside the US.

Founded in 2001 by Don Palmieri, family-owned GCAL is known for providing diamond certificates carrying a guarantee, rather than just reports that act as a description of grades. In 2021, it launched 8X, a cut-grading standard that it claims is more exacting than the industry’s triple Ex score.

“Sarine’s technologies will allow us to continue to abide by [our] key code of ethics while still expanding our services to meet the growing demand by consumers seeking confidence that their acquired products and services meet all norms of quality and sustainability,” said GCAL chief operating officer Angelo Palmieri.
