Lab-Grown Diamonds: Do They Stay As much as the Hype?

The diamond business has been rife with controversy for many years, each humanitarian and environmental. Lately, there was a rising hype round lab-grown diamonds, which many see as a extra moral and environmentally acutely aware various to historically mined diamonds. The manufacturers producing them definitely market them that approach. 

Analysis has proven that just about 70% of millennials, the demographic that contains a majority of the marketplace for diamonds for engagement rings, would contemplate a lab-grown diamond for an engagement ring. Along with moral and environmental causes, many acknowledged the decrease value of lab-grown diamonds as an vital issue of their choice. In line with a report conducted by Bain, the worth of lab-grown diamonds is anticipated to proceed dropping, making them accessible to a bigger part of the market. 

However is that this sparkly resolution too good to be true? We did some digging to seek out out. 

First up, what precisely is a lab-grown diamond? 

There are two methods used to create diamonds in labs: high-pressure, high-temperature (HPHT) and chemical vapor deposition (CVD). For HPHT, the diamond is engineered from graphite, utilizing machines that generate excessive stress or warmth, replicating situations through which naturally shaped diamonds had been created. CVD, however, is a technique of rising a strong diamond from a hydrocarbon gasoline combination on a substrate materials. 

Bodily, the ensuing artificial diamond is almost an identical to a mined diamond, and also you undoubtedly received’t have the ability to differentiate it simply by taking a look at it.  

Lab-grown vs. Mined Diamonds: Environmental Influence

When evaluating the environmental affect of lab grown versus mined diamonds, each the overall quantity of vitality wanted in addition to the form of vitality used are vital elements to contemplate. For instance, a lab might have a excessive vitality utilization to supply a diamond, but when that vitality comes from clear, renewable sources, it might nonetheless be a greater possibility than a mine that makes use of oil to energy its actions. 

“Diamond mining sometimes requires diesel for the vehicles and different gear. Energy can be required for the processing plant,” says business analyst Paul Zimnisky. Lab-diamond manufacturing can eat very important quantities of vitality, as in some instances the expansion chamber needs to be heated to the temperature of the solar. The method also can require gases akin to methane, nitrogen, and boron.” 

Power and gas utilization varies broadly amongst artificial diamond labs and mines. In line with a 2016 paper by Saleem H. Ali, Professor of Power and the Setting on the College of Delaware, the Argyle mine in Western Australia has a gas utilization of 4.2 kilos per carat, and the Diavik mine in distant northern Canada makes use of 11.5 kilos per carat created by diesel mills. 

In the meantime, on the subject of vitality, the Argyle mine required 7.5 kWh of vitality per carat, artificial lab Gemesis used 20 kWh of vitality per carat, the lab Apollo Diamonds required 28kWh per carat, the Diavik mine used 66.3 kWh per carat, and the De Beers’ marine mine off the Skeleton Coast of Namibia consumed 80.3 kWh per carat, no less than in 2016. These numbers might have modified, but it surely demonstrates that neither mines nor labs could be assumed to be higher than the opposite.  

Nevertheless, Ali cautioned in his paper that we shouldn’t take these numbers at face worth. For proprietary causes, diamond producers don’t at all times disclose the supplies they use to make the artificial diamonds. And this issues lots. If comparatively ample metals like iron and copper are used for manufacturing, the environmental affect might be considerably decrease than if the manufacturing course of makes use of uncommon earth metals.

Equally, on the subject of chemical utilization, there’s no option to actually know what precisely goes into these lab-grown diamonds, and the way these chemical compounds are being disposed of, except the corporate decides to launch that data. 

Alternatively, “Chemical substances should not sometimes utilized in diamond mining and restoration, as the method sometimes simply consists of crushing the rock till the diamonds are liberated. Diamond mining is taken into account one of many cleanest types of mining, but it surely does require water to ‘wash’ particles when liberating the diamonds,” says Zimnisky. 

Wanting on the complete image

When discussing sustainability, we will’t cease at details and figures associated to environmental affect. The societal, financial, and humanitarian impacts on native communities are equally vital elements to contemplate, and sure mines (if managed effectively) present robust advantages to those communities. 

We work with artisanal diamond mining communities to help their empowerment and diamond mining is a crucial supply of revenue for these communities and producer nations,” says Zuzia Danielski, Communications Director at IMPACT, a non-profit working to handle the sourcing of pure assets in areas of battle. “Lab-grown diamonds are diverting vital revenue away from creating communities. Our work is to make sure pure assets, like diamonds, can help sustainable improvement in producing international locations and artisanal mining communities.”

In “The Diamonds of Botswana,” the third a part of “Fashionscapes,” a docu-series exploring the style provide chains, Livia Firth talked to folks working within the diamond mining business in Botswana and located that the diamond business supplied many alternatives to the locals, whether or not it was employment, schooling, or entry to know-how. 

“We had been the poorest nation in Africa, and diamonds had been found simply after independence. And the constructions that had been put in place at the moment have benefitted Botswana going ahead,” Naseem Lahri, the Managing Director of Lucara Botswana, informed Firth. “I used to be born in Botswana, I’ve schooled in Botswana, and I’ve gone to College in Botswana, and it’s all due to the diamonds which have created the faculties that I’ve schooled at, and even the employment proper.”

“In Botswana, what occurs is that each one authorities revenues from minerals are put right into a central pool after which it’s used for the event of the nation,” says Susanne Swaniker, CFO of World Sightholder Gross sales on the De Beers Group. She acknowledges that the diamonds aren’t a renewable useful resource and a few level the mines will run dry. That’s why, in response to her, it’s key for the federal government to make use of the income from the business well, and make investments it in improvement to create different sustainable industries that may proceed to maintain the financial system even after the diamond mines are tapped out. 

“The socio-economic empowerment that’s taking place on account of diamonds in Botswana is a take a look at of what could be achieved,” says Pat Dambe, vp of company affairs and authorities relations on the De Beers Group. “I’m a product of the diamond business. All people that you just meet in Botswana is a product of it as a result of it’s been our coronary heart and soul. It took us from being the third poorest nation in Africa to being most likely essentially the most profitable medium-sized economies.”

After all, this isn’t at all times the case. There have been a number of situations the place diamond mining has been damaging to native communities and other people. For instance, a study by the Kimberley Process Civil Society Coalition examined the affect of diamond mining on close by communities in Lesotho in Southern Africa and located shockingly excessive ranges of nitrate in water sources for communities in surrounding villages, in addition to a scarcity of employment alternatives and environmental air pollution. Another study by the identical coalition discovered that 133 youngsters below the age of 15 had been working throughout 13 mining cites in Boda, and one other 15 every in Berberati and Nola within the Central African Republic. 

One of many predominant responses to the outcry in opposition to blood diamonds was the Kimberley Process, which goals to eradicate battle diamonds from the worldwide provide chain. Nevertheless, the important thing right here is to grasp the way it defines battle diamonds: “tough diamonds used to finance wars in opposition to governments.” 

A Kimberly Course of certificates (simply) signifies that a diamond was not a supply of revenue for a insurgent group overthrowing a legit authorities,” says Zimnisky. 

It doesn’t get into different impacts of diamond manufacturing, together with employee situations and environmental affect. So whereas it’s an excellent benchmark to keep away from diamonds which can be used to fund insurgent teams, it doesn’t inform us far more past that.

It All Comes All the way down to Transparency

Sadly, there is no such thing as a hard-and-fast rule on the subject of selecting between lab versus mined diamonds. As in most issues in vogue, it’s much less concerning the materials and extra about transparency. 

For my part, proper now no less than, the lab-diamond business is far much less clear than the pure diamond business,” says Zimnisky. “There’s loads of “greenwashing” by many lab-diamond corporations, which is why, once more, this must be taken on a case by case foundation.”

So theoretically, whereas a lab-grown diamond might have a decrease environmental affect than a mined one if created below optimum situations, now we have to take claims made by manufacturers with a grain of salt. 

Moreover, and that is the shocking one, mined diamonds (when mined responsibly), present important advantages for the native communities. If stopped, the livelihoods of those communities may very well be misplaced. 

“Our view is that the business must help the situations for traceability and due diligence so that buyers can have faith within the alternative they make if they’re shopping for a mined diamond,” says IMPACT’s Danielski.

Backside line: Do your analysis. Mined or artificial, your jeweler ought to have the ability to let you know the journey of the diamond all the way in which from the place and the way it was mined or created, to how the jewelery was produced and offered. 

“I might argue {that a} recycled (repurposed or second-hand) diamond has the bottom environmental affect of all – and this doesn’t sometimes come up on this dialog,” concludes Zimnisky. 

We are inclined to agree.
