Are Laboratory-Grown Diamonds Really Sustainable and Eco-Friendly?

Diamonds have long been revered for their beauty, rarity, and association with luxury. However, traditional diamond mining comes with ethical concerns and environmental impacts. In recent years, laboratory-grown diamonds have emerged as an alternative, marketed as a sustainable and eco-friendly choice. This article explores whether laboratory-grown diamonds truly live up to their claims of sustainability and environmental friendliness.

The Process of Laboratory-Grown Diamonds:
Laboratory-grown diamonds, also known as synthetic or cultured diamonds, are created in controlled environments using advanced technology. They are produced through two primary methods: High-Pressure High-Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both methods involve replicating the natural conditions that cause diamond formation but in a shorter time frame.

Environmental Impact:
a) Land Disruption: Traditional diamond mining often requires extensive land clearing and excavation, leading to habitat destruction and soil erosion. In contrast, laboratory-grown diamonds are produced in labs, eliminating the need for land disruption.

b) Energy Consumption: The production of laboratory-grown diamonds does require significant energy inputs, mainly in the form of electricity. However, advancements in technology have made the process more efficient, reducing energy requirements over time. Renewable energy sources can also be used to power these facilities, further minimizing their carbon footprint.

c) Water Usage: Traditional diamond mining can consume substantial amounts of water, contributing to local water scarcity and ecosystem degradation. Laboratory-grown diamond production generally requires significantly less water, making it a more environmentally friendly option.

d) Chemical Usage: While the production of laboratory-grown diamonds involves the use of chemicals, the industry is continually striving to reduce their environmental impact. Responsible manufacturers are working on developing greener chemical processes and minimizing the use of harmful substances.

Ethical Considerations:
Traditional diamond mining has long been associated with human rights issues, including exploitative labor practices and conflicts (so-called “blood diamonds”). Laboratory-grown diamonds, on the other hand, offer a more transparent and traceable supply chain. Consumers can be confident that their diamonds are not contributing to human suffering or funding conflicts.

Long-Term Sustainability:
a) Repurposing Waste: Laboratory-grown diamond production generates significantly less waste compared to mining. Additionally, by-products from the manufacturing process can be repurposed, further reducing the ecological impact.

b) Circular Economy: As laboratory-grown diamonds gain popularity, a potential future advantage lies in their ability to be recycled and repurposed. This aligns with the principles of a circular economy, where materials are reused rather than discarded.

Conclusion:

Laboratory-grown diamonds offer an alternative to traditional diamond mining that addresses many of the ethical and environmental concerns associated with the industry. While there are energy and chemical inputs involved, the overall impact is significantly reduced compared to mining. Furthermore, the transparency and traceability of laboratory-grown diamonds provide assurance to consumers seeking an ethical and sustainable choice.

As with any industry, continuous improvements are needed to enhance the sustainability of laboratory-grown diamond production. Manufacturers should prioritize the use of renewable energy, minimize chemical usage, and explore recycling options. By doing so, laboratory-grown diamonds can truly become a more sustainable and eco-friendly option, offering consumers the beauty and luxury they desire without compromising the environment or human rights.

Botswana threatens break-up with De Beers in push for better diamond deal

Botswana may not renew a five-decade sales agreement with De Beers if the diamond producer doesn’t offer a larger share of rough diamonds to the state’s gem trading company, Okavango Diamond Company (ODC).

The move comes after the southern Africa nation acquired last month a 24% stake in Belgian diamond processing firm HB Antwerp for an undisclosed sum.

Analysts saw this deal as a way for Botswana to loosen the Anglo American-owned miner’s grip on its diamond sector, which is a major source of employment and tax revenue for the country.

De Beers and Botswana jointly own Debswana, which mines almost all of the roughs gems in the country — the world’s second-largest diamond producing nation after Russia.

The partnership has helped Botswana become one of Africa’s fastest growing economies, while supplying De Beers 75% of Debswana’s rough diamonds, which are then sorted and sold to sightholders around the world.

Debswana’s diamond sales hit a record $4.6 billion in 2022, compared to $3.4 billion in 2021.

President Mokgweetsi Masisi has threatened to walk away from the talks if Botswana does not get a larger share of Debswana’s output for marketing outside the De Beers system.

The government has not publicly stated what share it seeks, but it is believed to be as high as 50%, double its current allocation.

The two parties have been negotiating for several years to extend their 2011 mining rights and sales agreement, which is due to expire in June this year.

“Colonial” model
Rafael Papismedov, co-founder of HB Antwerp, told the Financial Times that a revised deal would help Botswana break free from the current model of being “stuck in a box that says you can only dig and wash the diamonds.”

Papismedov added that De Beers’ operating model carries on “colonization” principles, acting as if Botswana was incapable of building midstream capabilities for polishing diamonds.

Masisi wants more locals employed in the diamond sector, which accounts for a fifth of the country’s gross domestic product.

The largest diamond producer by value has said it is confident that it can maintain its partnership with Botswana, but that some of the negotiations are complex and require more time.

De Beers has said that the arrangement must make economic and strategic sense for both parties, adding that it is committed to supporting Botswana’s aspirations to grow its diamond industry.

The stakes are high for both sides, as they seek to secure their future in a volatile and competitive industry that has been hit by the covid-19 pandemic, changing consumer preferences and ethical concerns.

A new deal between Botswana and De Beers could have significant implications for the global diamond supply chain and the balance of power in the sector.

De Beers finds diamond within a diamond, names it the “Beating Heart”

De Beers, the largest diamond producer by value, has unveiled a unique piece it named the “Beating Heart”, a 0.33-carat rough specimen that consists of a diamond within another diamond.

The unusual discovery – a D-colour, type IaAB diamond – has an internal cavity enclosing a smaller loose diamond, which is trapped, yet free to move around within the space.

De Beers said the gemstone was discovered at one of its mines in either Africa or Canada, but the exact origins can’t be pinpointed.

It arrived at the De Beers Institute of Diamonds facility in Maidenhead, England, in November last year, where it was verified to be a natural occurring stone.

Initial conclusions from the Institute’s experts suggest that an intermediate layer of poor-quality diamond etched away during its travel to the surface of the Earth, leaving only the better-quality material: the outer diamond and the core.

“The ‘Beating Heart’ is a remarkable example of what can happen on the natural diamond journey from formation to discovery,” Jamie Clark, Head of Global Operations at De Beers Institute of Diamonds, said in the statement.

Now registered on De Beers’ Tracr blockchain platform, which certifies a diamond’s provenance and production journey, the “Beating Heart” will be kept in its rough form for research and educational purposes.

Competitor Alrosa found a similar diamond in 2019, which was named “Matryoshka” after the famous Russian nesting dolls. The 0.62 carat gem, estimated to be over 800 million years old, resulted from one diamond growing inside another, according to Alrosa’s scientists.

The 10.57-Carat ‘Eternal Pink’ Diamond Could Fetch $35 Million At Sotheby’s

“The Eternal Pink,” a 10.57-carat internally flawless fancy vivid purplish-pink diamond, will be offered at Sotheby’s New York on June 8. Its estimate is $35 million, which if achieved, would make it one of the most valuable gems ever sold at auction.

Its per-carat estimate of more than $3.3 million is the largest such estimate ever placed on a diamond or gemstone, according to Sotheby’s.

Quig Bruning, head of Sotheby’s Jewelry, Americas, says it’s the most vivid pink diamond to ever to come to market. “This color is the most beautiful and concentrated shade of pink in diamonds that I have ever seen.”

The cushion-shaped diamond will first be on view in Hong Kong April 1 – 7 to coincide with the 50th anniversary of Sotheby’s presence in Asia. The gem will then travel to Dubai, Singapore, Shanghai, Taiwan and Geneva before being offered as the top lot at Sotheby’s New York Magnificent Jewels auction on June 8.

The 23.78-carat rough which yielded The Eternal Pink was mined by De Beers at the Damtshaa mine in Botswana. Diamond manufacturer, Diacore, took six months to cut and polish the gem into its current color, described as “bubblegum” by the auction house.

“This stunning diamond is the best of the best when it comes to exceptional pink diamonds and it is difficult to overstate its rarity and beauty,” said Wenhao Yu, chairman of Jewellery and Watches at Sotheby’s Asia.

Sotheby’s has had some experience with important pink diamonds. The auction house sold the record-breaking CTF Pink Star, a 59.60-carat oval mixed-cut Fancy Vivid Pink Internally Flawless diamond, sold for $71.2 million—a world auction record for a diamond and any gemstone or jewel—in Hong Kong in April 2017. More recently, Sotheby’s sold the Williamson Pink Star, an 11.15-carat fancy vivid pink internally flawless diamond, for $57.7 million in a single-lot auction at Sotheby’s Hong Kong on October 8, 2022, setting the world record price per carat for any diamond or gemstone at more than $5.1 million.

Colored diamonds continue to demand high prices at auction with exceptional pink and blue diamonds leading the way. It is because of their rarity, according to Sotheby’s. Of all the diamonds submitted to the Gemological Institute of America, fewer than 3% are classified as colored diamonds. Within these colored diamonds, pink is one of the rarest to occur naturally in diamonds. A diamond that is more than 10 carats, with strong color, internally flawless clarity, and classified as a “vivid pink,” the highest grade for a pink diamond is extremely rare.

Mined diamond compared to laboratory grown diamond

*Mined Diamond and laboratory grown diamond*

Diamonds have long been a symbol of love, luxury, and status. However, in recent years, there has been a growing interest in the production of laboratory-grown diamonds as a more ethical and sustainable alternative to mined diamonds. In this article, we will explore the differences between a mined diamond and a laboratory-grown diamond.

Mined Diamonds:

Mined diamonds are formed naturally over millions of years deep beneath the earth’s surface. These diamonds are found in mines, usually in remote locations, and are extracted using heavy machinery and explosives. The mining process is often associated with negative environmental and social impacts, such as habitat destruction, water pollution, and exploitation of workers.

Mined diamonds are valued for their rarity and unique characteristics. The quality of a diamond is determined by the 4Cs – cut, clarity, carat weight, and colour. The more perfect a diamond is in each of these categories, the more valuable it is considered to be.

Laboratory-grown Diamonds:

Laboratory-grown diamonds are created using advanced technological processes that mimic the natural formation of diamonds. These diamonds are produced in a laboratory environment, where conditions are controlled and monitored to ensure consistent quality and purity.

The process of creating a laboratory-grown diamond involves using a small diamond seed, which is placed in a chamber and exposed to extreme heat and pressure. Over a period of weeks, carbon atoms are deposited onto the seed, gradually building up the crystal structure of the diamond.

The resulting laboratory-grown diamond is physically and chemically identical to a mined diamond, and can be graded using the same 4Cs criteria.

Differences between Mined Diamonds and Laboratory-grown Diamonds:

Mined diamonds and laboratory-grown diamonds have very similar chemical properties, as they are both made of pure carbon atoms arranged in a crystalline structure. However, there are some subtle differences in the impurities and defects that can be present in each type of diamond.

Mined diamonds can contain trace elements such as nitrogen, boron, and hydrogen, which can affect the diamond’s colour and other properties. Laboratory-grown diamonds can also contain these impurities, but they can be controlled more precisely during the growth process to produce diamonds with specific colours and properties.

One key difference between mined and laboratory-grown diamonds is the presence of defects in the crystal structure. Mined diamonds can contain defects such as vacancies, dislocations, and impurity atoms, which can affect the diamond’s hardness and other physical properties. Laboratory-grown diamonds are typically more pure and have fewer defects, which can make them more consistent in their properties and easier to work with for industrial and scientific applications.

In terms of their chemical composition, both mined and laboratory-grown diamonds are made of pure carbon, with each carbon atom bonded to four neighboring carbon atoms in a tetrahedral arrangement. This gives diamonds their unique hardness and other physical properties, as well as their optical properties such as high refractive index and dispersion.

Overall, while there are some subtle differences in the impurities and defects that can be present in mined and laboratory-grown diamonds, they are both essentially the same material in terms of their chemical properties.

One of the key differences between mined diamonds and laboratory-grown diamonds is their origin. Mined diamonds are natural, formed over millions of years in the earth’s mantle. Laboratory-grown diamonds, on the other hand, are created using advanced technological processes in a laboratory.

Another difference is the environmental and social impact of the two types of diamonds. Mined diamonds are often associated with negative environmental and social impacts, such as habitat destruction, water pollution, and exploitation of workers. Laboratory-grown diamonds, on the other hand, are generally considered to be more sustainable and ethical, as they do not involve the same level of environmental destruction or human exploitation.

Finally, there is a difference in price between mined diamonds and laboratory-grown diamonds. Mined diamonds are generally more expensive, due to their rarity and the high costs associated with mining and extraction. Laboratory-grown diamonds, on the other hand, are often less expensive, as they can be produced in larger quantities and do not require the same level of mining and extraction.

Conclusion:

Mined diamonds and laboratory-grown diamonds both have their pros and cons. While mined diamonds are valued for their rarity and unique characteristics, they are often associated with negative environmental and social impacts. Laboratory-grown diamonds, on the other hand, are more sustainable and ethical, but may be less valuable due to their artificial origin. Ultimately, the choice between a mined diamond and a laboratory-grown diamond comes down to personal values and priorities.

HB Antwerp Invests in Botswana’s Young Diamond Talent

HB Antwerp has announced a partnership with Botswana to foster a new generation of diamond talent.

It has signed a a five-year memorandum of understanding with the Botswana International University of Science and Technology (BIUST).

They will jointly organize traineeships for Botswanan youth, offer scholarships for promising local talent, drive innovative projects backed by digital supply chains, and create job opportunities in the diamond sector.

The move comes as Botswana threatens to walk away from its long-standing sales agreement with De Beers, which is due for renewal at the end of June.

There has been media speculation that the Okavango Diamond Company (ODC), wholly owned by the Botswana government, was planning to sell its specials (+10.8-carats) to Belgian manufacturer HB Antwerp and to Canada-based Lucara and instead of De Beers.

HB Antwerp says it promotes respect for local communities, fair labor and pay, and investment in skills training and job placement opportunities for local workers.

Rafael Papismedov, its managing partner and strategy director, said: “Young people in Africa have incredible potential, but often do not have access to meaningful opportunities.

“We believe in the power of diamonds to catalyze positive change and look forward to leveraging this partnership to deliver on that potential for the Botswanan people.”

How do I know where my diamond was mined ?

It can be challenging to determine the exact location where a diamond was mined, but there are several ways to get an idea of its origin:

Diamond certificate: A diamond certificate or grading report from a reputable laboratory such as GIA, AGS, HRD, IGI or DCLA will provide information about the diamond’s characteristics, including its colour, clarity, and carat weight. Some certificates may also include information about the diamond’s origin or a statement that the diamond is of natural origin.
Inscription: Some diamonds may have a laser inscription on the girdle (the thin outer edge) of the diamond that identifies the diamond’s report and sometimes brand origin or other information about the diamond. The inscription is a laser inscription or a micro-inscription that can only be viewed under magnification.
Jewellers and diamond dealers: An experienced jeweller or diamond dealer may be able to provide information about the diamond’s origin based on their knowledge and experience in the industry.
Diamond tracing programs: Some diamond companies offer programs that trace the origin of their diamonds from the mine to the consumer. For example, the De Beers Group has a program called Tracr that provides a digital certificate of a diamond’s journey from mine to retailer. It’s important to note that not all diamonds can be traced to their exact origin, but the above methods can provide some information about a diamond’s potential source.

Diamonds can be found in various places around the world, but the most famous diamond sources are:

Botswana: Botswana is the world’s leading producer of diamonds by value and is responsible for about 25% of the world’s diamond supply.
Russia: Russia is the world’s largest diamond producer by volume, accounting for about 27% of global diamond production. The majority of diamonds mined in Russia come from the Yakutia region in northeastern Russia.
Canada: Canada is the world’s third-largest diamond producer, and its diamond mines are known for producing high-quality gemstones. The majority of Canada’s diamond mines are located in the Northwest Territories.
Australia: Australia is known for producing some of the world’s most valuable pink and red diamonds. The Argyle Diamond Mine in Western Australia was the world’s largest source of pink diamonds until its closure in 2020.
South Africa: South Africa is one of the earliest sources of diamonds, and the country’s Kimberley region is famous for its diamond mines. The Cullinan Diamond, the largest rough diamond ever found, was discovered in South Africa in 1905.

HRD Antwerp Hits Back at ‘Upgrading’ Allegations

HRD Antwerp has sued its former Turkish partner company following allegations the Belgian laboratory had routinely “upgraded” diamonds.

The organization is in a dispute with Enstitü Istanbul Bilim Akademisi Yönetim Danışmanlığı, with which it ended a longstanding collaboration in 2021.

The messy divorce intensified last week when the Belgian press reported allegations that HRD, in 2020, had introduced a strategy of giving diamonds higher grades than other laboratories. On Wednesday, HRD said it had taken legal action against its former partners in Turkey for “damaging its business reputation.”

Belgian lawsuit

The disagreement revolves around a civil lawsuit that Enstitü Istanbul Bilim Akademisi Yönetim Danışmanlığı filed in late 2021 against HRD at an Antwerp court, according to a March 9 report by Belgian newspaper De Tijd. Investigators have also been looking into whether there was anything suspicious about the HRD’s grading methods, the report added.

Nearly six years ago, according to De Tijd, the International Diamond Council (IDC) — which the World Federation of Diamond Bourses (WFDB) set up in the 1970s to unify diamond grading around the world — excluded HRD from its membership. In a letter to HRD’s then CEO Michel Janssens, IDC president Harry Levy wrote that it was “no longer the case” that HRD graded according to IDC rules, the newspaper reported.

By then, HRD was in a bad financial state, according to leaked internal slides that the newspaper cited. This was still the case in 2020, when another leaked document read: “With current results, HRD is out of business,” the Dutch-language report said.

In a new strategy, HRD determined that stones that already had Gemological Institute of America (GIA) reports were allowed to receive one or two color “upgrades” or one clarity “upgrade,” the report alleged. The lab was not to downgrade the diamonds unless there had been a genuine mistake, the report continued. Stones from IGI were not allowed to receive an upgrade, it said. The paper cited an internal online meeting in which Mike Davey, then director of HRD Antwerp Istanbul, shot down the policy as a “way to commit market fraud.”

In the same meeting, HRD Istanbul owner Mehmet Can Özdemir said, according to the report: “Valuing diamonds involves a certain amount of subjectivity. If things are really tight, graders can go higher or lower. But that is never about one full degree. In our scenario, we immediately jump up two.”

HRD performed an audit of its standards following the allegations and found no irregularities, its CEO, Ellen Joncheere, told Rapaport News Wednesday.

“We are in fact a bit more lenient [than the GIA] on color but stricter on cut and fluorescence, but this is known by the market,” Joncheere said.

Trademark disagreement

On Wednesday, HRD also responded with allegations that Özdemir had “made shady deals” and had used HRD’s power and reputation unfairly.

“One of the main reasons for the termination [of the partnership] was that the partners holding the management of the company did not transfer the trademark ‘HRD,’ which was unfairly registered in the name of HRD Istanbul, to the clients [HRD Antwerp], despite their previous commitments,” said Tuncay Çaltekin, HRD Antwerp’s attorney, in a statement Wednesday.

The partners also placed liens on the HRD trademark through other companies owned by their family members and transferred HRD’s assets into those companies, Çaltekin alleged. “In other words, they committed irregularities contrary to the agreement,” he claimed.

Meanwhile, Joncheere gave an interview to Belgian newspaper Het Laatste Nieuws (HLN), published Wednesday, in which she alleged there had been “tax and financial fraud” at the Turkish counterpart.

Özdemir dismissed the CEO’s claims as “pathetic, dishonest and desperate.”

How are diamonds priced ?

*Diamond Colour is one of the 4c’s used to calculated diamond value*

Polished diamond prices are derived from a variety of factors, including supply and demand, the quality and characteristics of the individual diamond, and market conditions.

The prices of polished diamonds are primarily determined by the 4Cs: carat weight, colour, clarity, and cut. These factors are assessed by gemologists and other experts who evaluate the diamond’s physical properties, such as its size, colour, clarity, and overall quality of cut.

Other factors that may influence the price of polished diamonds include the type of diamond, such as whether it is a natural or lab-grown diamond, the country of origin, and the overall market conditions for diamonds. Additionally, the reputation and credibility of the seller or the dealer can also affect the price of the polished diamond.

Overall, polished diamond prices are determined by a complex combination of factors, and can fluctuate over time based on changes in supply and demand, market conditions, and other economic and industry factors.
There is no single diamond price list that accurately reflects the prices of all diamonds. This is because the price of a diamond depends on a number of factors, including its size, shape, colour, clarity, and other characteristics.

That being said, there are various industry-standard diamond price lists that are commonly used as references by professionals in the diamond trade. These lists are typically based on a standardized grading system and provide price ranges for diamonds of different sizes, shapes, and quality grades.

The most commonly used diamond price list is the Rapaport Diamond Report, which provides a benchmark price for diamonds based on their 4Cs grading (carat weight, colour, clarity, and cut). However, it is important to note that the Rapaport price list only reflects the wholesale price of diamonds and may not necessarily reflect the retail price that consumers will pay.

Other diamond price lists include the International Diamond Exchange Price List, the Idex Diamond Price Report, and the Polished Prices Diamond Index, among others. These price lists may differ in their methodologies and grading systems, and the prices they list may vary slightly from one another.

Ultimately, when buying or selling a diamond, it is important to work with a reputable and knowledgeable diamond professional who can help you evaluate the diamond’s characteristics and provide you with an accurate price estimate based on current market conditions.
