Will Lab-Grown Diamonds Ever Be Considered True Luxury?

Diamonds may be forever, but the way we define luxury in the gem world is clearly in flux. Picture this: a perfect diamond shining as bright as any pulled from the depth of Earth, except this one was made in a lab, in the absence of environmental toll or billion-year wait. Once written off as mere imitation, lab-grown diamonds are set to shake the very core of the traditional luxury diamond market. But can a stone made in weeks ever be truly luxurious? Or are we seeing the dawn of a new definition of opulence — one that prizes ethics and accessibility above all considerations of scarcity and extravagance?

Lab-created diamonds have arrived. And, not only do they change how diamonds make money, but they also challenge the very nature of what we think of as luxury.

How Lab-Grown Diamonds Work

First of all, the science: A lab-created diamond shares the same chemical, physical, and optical properties as its mined brethren. Grown using two major processes, High-Pressure High-Temperature (HPHT) and Chemical Vapor Deposition (CVD), these diamonds essentially mimic the natural processes that create diamonds within the Earth. The result: a diamond with the same crystal structure and shining clarity as any stone pulled out of the mines of Botswana.

The key difference is time," says H. M. Strong in a review in The Journal of Physical Chemistry. "What would take nature billions of years, we are growing in days, or even in weeks." The Gemological Institute of America, the authority on diamond certification, has treated lab diamonds as real diamonds since 2018, grading them with the same terms as mined stones. Those days are over when lab-created gems were described as "synthetic" or inferior.

However, the notion of luxury has always transcended the technical brilliance of a gem alone. It's also about the story behind it, something which lab-grown diamonds are very actively rewriting.

Economics vs. Exclusivity

Luxury and exclusivity are inextricably linked, and herein lies the challenge for lab-grown diamonds. But a 1-carat lab-created diamond, which costs about $300 to $500 to make, is being sold for $2,500 to $4,000-a far cry from the $6,000 to $10,000 price of a mined diamond of comparable quality, according to industry analyst Paul Zimnisky. Much of this wide disparity in pricing is due to the economics of production. For one, lab-made diamonds can be produced on demand and largely avoid the high costs of exploration, mining, and logistics. The process, as described in Crystal Growth & Design, is increasingly efficient and scalable, meaning the supply of lab-grown diamonds is, for all intents and purposes, unlimited.

This ubiquity completely upends the historic concept of rarity, a hallmark of luxury. As Martin Rapaport, chairman of the Rapaport Group, so aptly put it, "Luxury has always been about scarcity-about having what others cannot. If diamonds are no longer rare, do they lose their allure?

But the answer is not quite so black and white as it might seem. Millennials and Generation Z buyers-now driving the diamond market, are redefining what constitutes luxury. To the new generation, exclusivity is about more than merely owning something rare; it's about owning something meaningful. The Journal of Crystal Growth highlights that while the initial investment in technology for producing lab-grown diamonds—such as CVD machines—can be high (ranging from $250,000 to $2 million per machine), the production cost per diamond plummets as more diamonds are produced. Over time, this has led to economies of scale, making lab-grown diamonds increasingly affordable. Despite this, the industry maintains a significant profit margin, as noted by Rapaport Magazine, where a lab-grown diamond that costs $300 to produce can still retail for over $3,000.

Ethical Luxury

Sustainability is no longer a nicety, but a necessity for modern luxury brands. Lab-grown diamonds are an overwhelming competitor to mined diamonds at a time when consumers are questioning the environmental and ethical implications of their purchases. According to a report by the International Grown Diamond Association, in 2020, producing a 1-carat lab-grown diamond released about 511 kilograms of CO2, compared to 1,400 kilograms for a mined diamond. Lab-grown gems avoid child labor, unsafe mining conditions, and the murky legacy of conflict or "blood" diamonds that has haunted the natural diamond trade.

That's ethical clarity far more valuable, to many buyers than the so-called prestige of a mined diamond. "I want a pretty fat ring… but I also want to know that my money isn't supporting environmental destruction or exploitation," says Jennifer Ali, a millennial engagement ring shopper quoted in a recent Axios report. Ali's sentiment is echoed across a growing demographic of consumers who value transparency and sustainability over tradition.

A 2021 report by Sustainable Luxury and Jewelry underscores that younger consumers—Millennials and Gen Z—are redefining luxury to focus less on exclusivity and more on ethical considerations. These consumers are highly attuned to issues like sustainability, traceability, and ethical sourcing. For them, the real luxury is knowing that their diamond did not contribute to environmental degradation or human rights abuses, which have long been associated with the natural diamond industry.

Lab-grown diamonds, with their smaller carbon footprint and transparent supply chain, offer exactly that. According to an MVI Marketing survey, nearly 70% of Millennials would consider a lab-grown diamond for an engagement ring, citing ethical sourcing as their primary motivation. For this generation, lab-grown diamonds represent a new kind of luxury—one that aligns with their values.

The Rise of Lab-Grown Glamour

The appeal of lab-grown diamonds is not limited to price-conscious consumers. High-end jewellers have started to fall in love with them, too. Jean Dousset, the great-great-grandson of Louis Cartier, introduced a lab-grown diamond jewellery collection under the banner "Never Mined. All Mine." His showroom in West Hollywood, which reaches a clientele looking for tailored designs, offers lab-grown diamonds whose customization can be done more inexpensively than mined diamonds.

Even celebrities are joining the fad. Lab-grown diamonds pop up from Billy Porter's glittering necklace at the Oscars to Emma Watson's responsible diamonds on the Vanity Fair Oscar Party red carpet; they're fast becoming the new status symbol. As Lady Gaga said, another lab-grown diamond devotee: "They shine just as bright, but with a story that's much better to tell.

It is a story of "better luxury" that has more advocates today, and designers like Anabela Chan and brands like Lark & Berry are at the forefront of this change. Their collections-adorned by the likes of Meghan Markle and Zoë Kravitz, provide diamonds with glamour and glitz sans ethical baggage.

Another key driver of the luxury appeal of cultured diamonds is personalization. Unlike mined diamonds, which are at the mercy of nature's whims, lab-created diamonds can actually be made to one's specific desires. Want a flawless 18-carat pink diamond? Lab-created options can grant that wish without waiting on nature's lottery.

According to industry expert Anil Kumar Bagathi, in Lab-Grown Diamond: The Shape of Tomorrow's Jewelry, "personalization has emerged as the new foundation of luxury. Consumers no longer want what everyone else has; they want something unique, something made just for them." Lab-grown diamonds, with their tailor-made designs at a fraction of the price of mined diamonds, are literally a perfect position to leverage such a trend.

The Future of Lab-Grown Diamonds

What is unmistakably evident is that lab-grown diamonds are here to stay. The question is not if they will be regarded as luxury, but how that very luxury will be reimagined to incorporate them. As consumers continue to put ethics, sustainability, and personalization at the forefront of their purchasing decisions, lab-grown diamonds might redefine what it means to be luxurious in the 21st century.

The diamond industry, said Bruce Cleaver, chief executive officer of De Beers, during a rare moment of candor, "is in the middle of an existential transformation. The future of luxury will look very different from the past."

Lab-grown diamonds will never have the exclusivity of the myth that mined diamonds do. Still, perhaps that is what makes them luxurious today. True luxury has always been about more than price, it's about meaning, and that's one thing these lab-grown gems have in spades.
The sparkle of a diamond is forever, but the future of luxury? That may belong to the lab.
