The diamond market is changing fast.

Lab-grown diamonds went from 12% of engagement ring sales in 2019 to 46% in 2023. That's not a small shift—it's a complete flip in how people buy diamonds.

I've been tracking this change for years, and what I'm seeing isn't just about price (though lab diamonds do cost 20-40% less than mined ones). It's about something deeper.

Are lab grown diamonds more ethical? The answer is pretty clear when you look at the facts.

Lab diamonds eliminate mining entirely. No digging up massive amounts of earth. No contaminating water supplies. No unsafe working conditions.

But here's what really caught my attention:

Mining a single carat of natural diamond requires 1 billion joules of energy. Creating the same diamond in a lab? Just 250 million joules.

The price gap tells the story too. Back in 2018, lab diamonds sold for only 20% less than natural ones. Today? That discount has jumped to 80%.

(Which explains why lab-grown diamonds have caused natural diamond prices to collapse.)

Throughout this article, I'll walk you through 11 facts about the diamond supply chain that most jewelry buyers never see. These insights explain exactly why lab-grown diamonds are winning over consumers—and why that trend will only accelerate in 2026.

Key Takeaways

Lab-grown diamonds are revolutionizing the jewelry industry by offering ethical, sustainable, and affordable alternatives to mined stones. Here are the most important insights from analyzing the diamond supply chain:

• Environmental impact is dramatically lower: Lab diamonds use 75% less energy, 86% less water, and create 99.98% less waste than mined diamonds

• Human rights violations are eliminated: Lab-grown gems avoid child labor, unsafe mining conditions, and conflict zone connections that plague traditional diamond mining

• Price advantage is massive: Lab diamonds cost 70-90% less than mined stones of identical quality, making luxury accessible to more consumers

• Supply chain transparency is complete: Unlike mined diamonds that pass through 7-8 middlemen, lab diamonds offer full traceability from creation to sale

• Gen Z drives market transformation: 46% of engagement rings now feature lab-grown diamonds, up from just 12% in 2019, as younger consumers prioritize ethics

The shift toward lab-grown diamonds represents more than a trend—it's a fundamental change in how consumers value sustainability, ethics, and transparency in luxury purchases. As technology continues advancing and renewable energy adoption increases, lab diamonds will only strengthen their position as the superior choice for conscious consumers in 2026 and beyond.

The Environmental Toll of Traditional Diamond Mining

Most people see a sparkling diamond and think "beautiful." They don't see the environmental destruction behind it.

Traditional diamond mining leaves scars on the planet that take decades to heal—if they ever do.

What Mining Actually Does to the Environment

The numbers are staggering.

Every single carat of mined diamond disturbs nearly 100 square feet of land and creates over 5,798 pounds of mineral waste. That's like excavating your entire backyard to find one small stone.

The land damage goes way beyond the initial dig. Mining operations strip away forests, cause massive soil erosion, and destroy wildlife habitats that animals depend on for survival. In many cases, the soil becomes so damaged it can't grow anything—ever.

But that's just the beginning.

Diamond mining operations pump out approximately 727 pounds of carbon dioxide per carat. A single mine can release roughly 164,900 metric tons of CO2 annually. To put that in perspective, that's like adding 35,000 cars to the road for a year.

Water gets hit hard, too. Mining consumes more than 126 gallons of water per carat, often draining local water supplies that communities depend on. The process contaminates nearby rivers and streams with sediment, chemicals, and heavy metals—poisoning fish and making water unsafe to drink.

How This Affects the Diamond Industry

These environmental problems create serious headaches throughout the diamond supply chain.

Consumers are getting smarter about environmental impact. They're asking tough questions about where their diamonds come from. Retailers now face pressure to prove their gems don't trash the planet.

The Kimberley Process tried to address some environmental concerns by requiring participating countries to implement environmental management plans. But these measures can't undo the fundamental problem: diamond extraction requires massive environmental destruction.

This reality has opened the door for cleaner alternatives.

Why Lab-Grown Diamonds Crush Mining on Environmental Impact

The environmental comparison isn't even close:

• Lab diamonds disturb just 0.07 square feet of land versus 100 square feet for mined stones

• They produce only 1 pound of mineral waste compared to 5,798 pounds

• They use approximately 18 gallons of water per carat instead of 126 gallons

• They create zero sulfur oxide emissions versus 30 pounds from mining

Lab-grown diamonds eliminate habitat destruction entirely. No digging up forests. No contaminating water supplies. No poisoning wildlife.

Many lab diamond companies now use renewable energy sources like solar and wind power. This makes their environmental footprint even smaller.

Yes, lab diamonds still need energy to produce. But the overall environmental impact stays dramatically lower than traditional mining. As more companies switch to clean energy, that gap will only get wider.

The Hidden Human Cost Behind Mined Diamonds

Most people don't want to think about where their diamonds come from.

I get it. When you're shopping for an engagement ring, the last thing you want to hear about is human suffering.

But the reality is hard to ignore.

The Human Toll You Don't See

Approximately one million children work in diamond mines worldwide. These aren't teenagers with part-time jobs—we're talking about kids working in dangerous conditions that would be illegal in any developed country.

Here's what actually happens:

Children crawl into unstable pits that collapse without warning. They develop respiratory diseases from dust, back injuries from hauling heavy rocks, and mercury poisoning that causes permanent brain damage.

Adult miners don't have it much better. In some regions, workers become victims of forced labor and human trafficking. Try to escape? You risk violence. And for this dangerous work, many African miners earn less than $1 per day.

The violence goes beyond the mines themselves. In Zimbabwe's Marange diamond fields, security forces have beaten women with batons and fired tear gas at families, sending children to hospitals.

One miner shared this with investigators: "The guards handcuffed me and my colleagues and ordered us to sit down. They set vicious dogs on us which mauled us for about 10-15 minutes as they watched, leaving us severely injured".

How These Diamonds Reach Your Jewelry Store

Despite all this, diamonds from these problematic sources still make it to market.

The Kimberley Process Certification Scheme was supposed to prevent "conflict diamonds"—but it has serious gaps. It only covers diamonds that fund rebel groups, not those linked to government abuses or human rights violations.

Here's the bigger problem: once diamonds get cut and polished, tracking their origin becomes nearly impossible. Problematic stones slip into the legitimate market undetected. Even diamonds with Kimberley certification might have been mined under terrible conditions.

Why Lab Diamonds Are Different

Lab-grown diamonds sidestep these ethical issues completely.

They're created in controlled environments, usually in countries with strong labor protections. This eliminates the risk of supporting:

• Child labor practices

• Unsafe mining conditions

• Human rights abuses

• Forced labor

Lab-grown gems offer complete traceability from creation to sale. You know exactly where your diamond came from and under what conditions it was made.

Now, I'll be honest about the complexity here. As one industry expert pointed out, "If people stop buying our diamonds, we won't be able to eat". Many communities do depend on diamond mining for survival.

The ideal solution isn't avoiding all mined diamonds—it's supporting initiatives that organize miners into cooperatives with fair wages and safe working conditions.

But until those reforms happen across the entire industry, lab-grown diamonds remain the clear ethical choice.

The Myth of Ethical Mining Certifications

Those "conflict-free" diamond certificates? They're not telling you the whole story.

The Kimberley Process—the main certification that's supposed to guarantee ethical diamonds—has some serious problems that most jewelry shoppers never hear about.

Certification Doesn't Mean What You Think It Means

Here's the thing: The Kimberley Process only covers "rough diamonds used by rebel movements to finance conflict aimed at undermining legitimate governments".

That's it.

A diamond can get certified as "conflict-free" even if it involves:

• Human rights abuses by governments

• Child labor and unsafe working conditions

• Environmental destruction

• Corruption and money laundering

Take Zimbabwe's Marange diamond fields. Government forces killed approximately 200 miners in 2008—yet diamonds from these fields still carry Kimberley Process certification.

The system gets even worse when you realize it certifies batches of rough diamonds, not individual stones. Once those batches get cut and polished, tracking becomes impossible. Only about 20% of diamonds can be traced back to their specific mine.

How This Affects What You Actually Buy

When you walk into a jewelry store asking for an ethical diamond, the staff usually can't tell you which country your stone came from, let alone which mine.

The Guardian calls the certification process "a convenient smokescreen"—and they're right.

Diamond parcels contain stones from multiple sources under one certificate. So even if you're trying to make an ethical choice, you're buying blind.

The numbers tell the real story: About 1 in 4 diamonds on the market today was mined under terrible conditions, despite having certification.

Even Global Witness—one of the organizations that helped create the Kimberley Process—eventually abandoned it after watching the scheme approve exports from Zimbabwe's controversial fields.

Why Lab-Grown Diamonds Actually Deliver on Ethics

Unlike the murky world of mining certification, lab grown diamonds offer something simple: complete traceability.

Every lab diamond can be tracked from the specific laboratory where it was created straight to your jewelry box. No guessing. No wondering if your purchase supported something you'd never want to fund.

Lab diamonds eliminate all the problems that certification schemes can't fix:

• No child labor

• No unsafe working conditions

• No human rights abuses

• No environmental destruction

Even Martin Rappaport, a leading figure behind the Kimberley Process, resigned from the system. When the people who created the certification admit it's broken, that tells you everything.

The choice becomes pretty clear when you compare a transparent lab-grown supply chain to a certification system that can't actually certify what matters most to conscious consumers.

The Energy Efficiency of Lab-Grown Diamonds

Energy consumption tells a different story than most people expect when you dig into the diamond supply chain.

Lab-grown diamonds do require substantial electricity to produce—typically 250-750 kilowatt hours (kWh) per carat. But that number needs context.

How Lab Diamond Energy Actually Works

The two main production methods have very different energy appetites:

• Chemical Vapor Deposition (CVD): Uses 500-2,000 kWh per carat

• High-Pressure High-Temperature (HPHT): Needs 800-2,500 kWh per carat

To put this in perspective, the average UK home uses just 10 kWh daily. So creating one lab diamond uses roughly the same electricity as powering a house for 2-8 months.

DeBeers claims their mining operations use only 80 kWh per carat—but here's what they don't include in that figure: exploration costs, transportation from remote mining sites, and all the infrastructure needed to reach diamonds buried deep underground.

The energy source matters enormously. Over 60% of lab diamonds currently come from China and India, where coal still powers much of the electricity grid. This connection to fossil fuels has created legitimate concerns about lab diamonds' true environmental impact.

How Smart Companies Are Solving the Energy Problem

Forward-thinking producers aren't just accepting high energy use—they're doing something about it.

Kira invested in a 100+ MW solar plant specifically to power its diamond manufacturing. Other companies are switching to wind and solar energy to cut their carbon footprint.

This shift creates transparency that's impossible with mined diamonds. You can now track both where your diamond came from AND what type of energy created it.

The Real Energy Comparison

When lab diamond producers use clean energy, the numbers become compelling:

Lab diamonds with renewable energy produce just 0.028 grams of greenhouse gas emissions per carat. Mining? 57 kilograms per carat.

Lab diamonds also avoid the hidden energy costs that mining requires—no exploration, no extraction equipment, no transportation from remote locations. Plus they eliminate creating 2.63 tons of mineral waste per carat.

The technology keeps improving too. Manufacturers are building more efficient reactors and heat recovery systems. Each improvement makes lab diamonds an even better choice for the diamond industry supply chain.

The Role of Traceability in Diamond Ethics

_{Image Source: McKinsey}

Most jewelry buyers have no idea where their diamond actually came from.

That's a problem when you're trying to make ethical purchases.

Explanation of Traceability

Here's how complicated diamond tracking gets: a single mined diamond can pass through up to 7-8 different owners before it reaches your finger. Each time it changes hands, the trail gets murkier.

Without proper tracking systems, there's no way to verify if your diamond was ethically sourced.

Blockchain technology is trying to solve this mess. Companies like Tracr (owned by De Beers) and Everledger create a "digital twin" for each diamond. Think of it as a permanent ID card that can't be forged.

Here's how it works:

When a diamond gets registered, it receives a unique digital signature recording everything—cut, clarity, color, origin. This ID follows the stone throughout its entire journey, creating what should be a tamper-proof record.

Impact on Diamond Supply Chain

The traceability push is changing how the diamond industry operates. Tracr now tracks over 2.8 million rough diamonds worth about $3.40 billion.

More importantly, blockchain tracking helps companies meet regulations like the OECD Due Diligence Guidance, which requires responsible mineral sourcing. Retailers can now tell customers the actual story behind their diamonds.

Fred Meyer Jewelers uses traceability platforms across 100 U.S. stores to show customers exactly where their diamonds traveled. It's the kind of transparency the industry desperately needed.

Why Lab-Grown Wins

Lab-grown diamonds make this whole traceability puzzle much simpler.

Since lab diamonds are created in controlled environments, every step gets documented from day one. No mystery middlemen. No lost paperwork. No wondering which country your diamond actually came from.

The manufacturing process allows for detailed record-keeping at every stage. Digital certification platforms give buyers complete access to information about each lab diamond's origin and characteristics.

Unlike mined diamonds that zigzag through multiple countries and change hands constantly, lab-grown diamonds have a straight path from laboratory to customer.

Simple. Transparent. Traceable.

That's exactly what conscious consumers want in 2026.

The Carbon Footprint Comparison

Here's a number that stopped me in my tracks:

A single carat of mined diamond creates 106.9kg to 160kg of CO2 emissions. That's like driving 265 miles in a regular car.

Now compare that to lab-grown diamonds.

What The Carbon Footprint Numbers Actually Show

Lab diamonds powered by renewable energy? Just 4.8kg of CO2 per carat. That's a 95% reduction.

Even lab diamonds using fossil fuel electricity max out around 40kg CO2 per carat. Still way better than mining.

But here's the catch I discovered:

Over 60% of lab diamonds come from China and India, where coal powers 63-74% of the electricity grid. This definitely raises their carbon footprint compared to labs using clean energy.

(Though they're still cleaner than mined diamonds.)

How This Changes Everything

The carbon pressure is real. De Beers promises carbon neutrality by 2030. Rio Tinto targets 50% emissions cuts by the same date.

Meanwhile, some lab diamond companies have flipped the script entirely.

They're now carbon-negative. These operations pull CO2 from the air to create diamonds, removing 20kg of carbon per carat.

Think about that: instead of polluting, these diamonds actually clean the atmosphere.

The Clear Winner

Even accounting for energy sources, lab diamonds win on carbon:

• No emissions from exploration and heavy machinery

• No 2.63 tons of mineral waste per carat

• No transportation from remote mining sites

The carbon-negative lab diamonds take this even further. They're not just avoiding environmental damage—they're actively helping fight climate change.

Are lab grown diamonds more ethical? When you see companies turning diamond production into a climate solution, the answer becomes pretty obvious.

The Price Transparency Gap

When you walk into a jewelry store today, the price tags tell a story most buyers don't expect.

Lab-grown diamonds cost 70% to 90% less than natural diamonds of identical quality.

Let me show you what this looks like in practice:

A 2-carat VS1 round lab diamond sells for $2,800. The exact same natural stone? $29,500.

That's not a small difference. That's life-changing money for most people.

Explanation of Pricing Issues

The gap keeps getting wider, too. Lab diamonds dropped 16.64% in price over the past year, while natural diamonds fell only 8.90%.

But here's what's interesting:

Both types get graded using the exact same standards. The 4Cs (cut, color, clarity, and carat) apply equally to lab and mined diamonds. So you're getting the same quality assessment either way.

The price difference comes down to how they're made, not what they actually are.

Impact on Diamond Supply Chain

Traditional diamond pricing involves a long chain of markups. Natural diamonds pass through multiple dealers, cutters, and retailers before reaching you. Each step adds cost.

Lab diamonds skip most of this complexity. The supply chain is shorter and more direct. Fewer middlemen mean lower prices.

This disruption has hit mining companies hard. Natural diamond prices collapsed after February 2022, forcing miners to stockpile rough stones. The volatility makes diamond mining a risky investment.

Why Lab-Grown Wins

You know exactly what you're paying for with lab diamonds. No mysterious markups or hidden costs.

The price trend speaks for itself. Lab diamonds went from a 20% discount in 2018 to an 80% discount today.

That explains the market shift. Nearly half of all engagement rings now feature lab diamonds, up from just 12% in 2019.

For buyers who want transparency—both in pricing and sourcing—lab diamonds deliver exactly that.

The Rise of Gen Z Ethical Shoppers

Have you noticed how different young shoppers are today?

Gen Z (born 1997-2012) approaches luxury buying completely differently than previous generations. They're not just looking for beautiful jewelry—they want to know the story behind every purchase.

What Gen Z Actually Wants

These young buyers make their first luxury purchases at age 15—four years earlier than millennials did. But here's what's interesting: 80% say ethical standards matter when making purchases.

I've seen this shift firsthand. When I look at recent surveys, 72% of Gen Z participants preferred lab-grown diamonds, specifically because they viewed them as more eco-friendly and ethically sourced.

Why? 61% of this generation worries about climate change—more than any other age group.

They also do their homework. Nearly 70% consider a trusted certification crucial when buying diamonds. Unlike older shoppers who might rely on sales staff recommendations, Gen Z researches extensively online first. They trust user reviews over traditional advertising.

How This Changes Everything

Jewelry brands have noticed. They're scrambling to highlight sustainability practices and ethical sourcing in their marketing.

The lab-grown diamond supply chain gives Gen Z exactly what they want—complete transparency about where and how their diamonds were created. Even traditional retailers who previously ignored lab diamonds are now adding them to their offerings.

Why Lab Diamonds Win With Young Buyers

Three reasons explain Gen Z's preference for lab diamonds:

Ethics matter. These diamonds eliminate worries about environmental damage and labor issues.

Affordability works. Lab diamonds cost 30-40% less than mined ones, so young buyers can get larger, better-quality stones within their budgets.

Values alignment. Lab diamonds let them make purchases that reflect their commitment to sustainability without sacrificing quality or beauty.

When you can get the same sparkle for less money and zero guilt, the choice becomes pretty obvious.

The Supply Chain Complexity of Natural Diamonds

Natural diamonds take one of the most convoluted paths to market I've ever seen in any industry. From mine to the jewelry store, these gems pass through so many hands that tracking becomes virtually impossible.

How Complex Supply Chains Actually Work

Here's something most people don't realize: a single diamond changes hands 8-10 times before it even gets a Kimberley Certificate. After that? It goes through thousands more hands and crosses countless borders before reaching customers.

The process gets messier because mining companies don't sell individual diamonds. They bundle rough stones into mixed parcels of different sizes and qualities. Manufacturers have no choice but to buy these grab bags—that's just how natural diamonds come out of the ground.

But here's where it gets really problematic:

When those diamond parcels reach a second country for processing, that country becomes the official "exporter" on paper. This completely breaks any chance of tracing where individual stones actually came from.

What This Means for the Industry

This tangled web creates serious problems throughout the diamond supply chain.

Manufacturers get squeezed financially because they must sell their current inventory fast to pay for the next batch of rough diamonds. This constant pressure weakens their negotiating power and creates razor-thin profit margins across the industry.

Geopolitical issues make everything worse. Russian diamonds represent 30% of the global supply, so sanctions have disrupted availability worldwide. These disruptions cause major price swings that nobody can predict.

Why Lab-Grown Diamonds Win

Lab diamonds cut through this mess entirely.

No mining means no complex extraction process. No remote locations means diamonds can be produced closer to where they're actually sold, which reduces both costs and complexity.

Most importantly, lab diamond production isn't tied to specific geographic locations. You can create them anywhere you have the technology and energy supply.

This straightforward approach gives buyers exactly what they want: transparency, predictable pricing, and a clear path from creation to purchase.

The Role of Technology in Lab-Grown Diamond Production

What's fascinating about lab-grown diamonds is the technology that makes them possible.

Two methods create these gems: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both have gotten incredibly sophisticated over the past five years, producing diamonds you literally can't tell apart from mined ones.

The HPHT process mimics what happens deep in the Earth—extreme pressure and heat. CVD grows diamonds layer by layer, like 3D printing with carbon atoms.

But here's where it gets really interesting.

How AI Changed Everything

Artificial intelligence now handles the tricky parts of diamond growing:

• Perfect growth conditions: AI adjusts temperature and pressure in real-time

• Quality control: It spots flaws as they form, not after

• Consistent grading: No human bias in evaluating the final gems

MIT researchers have even developed quantum-enhanced CVD systems that track individual carbon atoms as they deposit. (That's atomic-level precision we're talking about.)

What This Means for Prices

These tech improvements have slashed lab diamond prices by 80-90% compared to mined stones. The market responded exactly how you'd expect—lab diamonds jumped from 1% of sales in 2015 to about 20% by 2024.

The supply chain also got simpler. Blockchain technology now tracks each diamond from the moment it's created. No more guessing where your diamond came from or who handled it along the way.

Why Technology Gives Lab Diamonds the Edge

The tech advantages keep stacking up:

• Cost efficiency: Production costs are 40-70% lower than mining costs

• Customization: Want a pink diamond? Or a specific shape? No problem

• Consistency: Every diamond comes out exactly as planned

Many manufacturers are now powering their labs with renewable energy. Solar-powered diamond production? That's something you'll never see with mining operations.

The technology keeps improving, too. What takes weeks to grow today might take days in a few years. Meanwhile, mining operations are still using the same basic methods they've used for decades.

It's hard to compete with that kind of innovation.

The Future of Sustainable Diamond Supply Chains

The jewelry industry is at a tipping point.

One-third of fine jewelry purchases will be influenced by ESG factors by 2026. That's not just a prediction—it's already happening in showrooms across the country.

Where the Market is Heading

The shift isn't subtle anymore. We've gone from 12% to 46% of engagement rings featuring lab-grown stones in just four years. This pace of change tells you everything about where consumer preferences are moving.

What's driving this? Transparency.

Companies are now using blockchain to track every diamond from the lab to the customer. When buyers can see exactly where their diamond came from and how it was made, the choice becomes obvious.

The Supply Chain Split

The diamond market is splitting into two distinct paths. One for traditional mining. One for lab-grown alternatives.

Lab diamonds are projected to capture 21% of the total market by 2026. The Asia-Pacific region leads this shift, with sales jumping from $6.53 billion to $7.56 billion in just one year.

That's not growth—that's market disruption.

The Clear Winner

When you look at what lab-grown diamonds offer:

• 30-40% lower prices than mined stones

• Zero environmental destruction

• Renewable energy production

The trend becomes clear. Younger buyers especially want diamonds that match their values without breaking their budgets.

The future isn't coming—it's here. Lab-grown diamonds have already won the argument. Now they're just winning the market.

Here's How Lab Diamonds Stack Up

After walking through all these facts, the numbers tell a pretty clear story.

I wanted to put everything side-by-side so you can see exactly what you're choosing between. This comparison covers every major factor we've discussed—from environmental impact to supply chain transparency.

Mined vs Lab-Grown Diamonds Comparison Table

Feature	Mined Diamonds	Lab-Grown Diamonds
Land Impact	Disturbs 100 square feet per carat	Disturbs only 0.07 square feet per carat
Water Usage	Uses 126 gallons per carat	Uses 18 gallons per carat
Waste Created	Creates 5,798 pounds of mineral waste per carat	Creates 1 pound of mineral waste per carat
Energy Use	Uses 1 billion joules per carat	Uses 250 million joules per carat
Price Comparison	More expensive (baseline price)	70-90% cheaper than mined diamonds
Supply Chain Steps	7-8 different owners before reaching the customer	Direct path from lab to customer
Carbon Emissions	106.9-160kg CO2 per carat	4.8kg CO2 per carat (with renewable energy)
Traceability	Hard to track origin, multiple middlemen	Complete tracking from creation to sale
Human Rights Issues	Linked to child labor, unsafe conditions	No human rights violations reported
Market Share (2023)	54% of engagement rings	46% of engagement rings
Water Pollution	Contaminates water with chemicals and metals	No water contamination reported
Price Trend (2022-2023)	Dropped 8.90%	Dropped 16.64%

The difference is striking when you see it all laid out like this.

Lab diamonds win on almost every metric that matters to modern consumers. Lower environmental impact, better ethics, complete transparency, and significantly lower prices.

It's no wonder they've captured nearly half the engagement ring market in just four years.

The Bottom Line

The numbers don't lie. Lab-grown diamonds have won over nearly half the engagement ring market in just four years.

This isn't a fluke or temporary trend. It's what happens when an industry finally offers consumers what they actually want: beautiful diamonds without the ethical compromises.

I've watched this shift happen in real time, and what strikes me most is how obvious the choice has become. Lab diamonds deliver identical quality at a fraction of the price, with none of the environmental destruction or human rights concerns.

The traditional mining industry is fighting a losing battle.

Young buyers, especially, have made their preferences clear. They want transparency, sustainability, and value—exactly what lab-grown diamonds provide. Meanwhile, mined diamonds come with murky supply chains, certification schemes that don't actually certify ethics, and prices that keep climbing while quality stays the same.

Technology keeps making lab diamonds better and cheaper. Mining, by contrast, gets harder and more expensive as easily accessible deposits run out.

Here's what I think happens next:

Lab diamonds will continue gaining market share as more consumers discover them. Prices for mined diamonds will keep falling as demand shifts. And the jewelry industry will adapt by embracing the technology that makes diamonds accessible to everyone, not just the wealthy.

The diamond supply chain needed this shake-up. Consumers deserved better options. And now they have them.

Lab-grown diamonds aren't just winning in 2026—they're redefining what the diamond industry looks like for the next generation.
