The Future of Diamonds Is Grown — Where the Industry Is Headed
Introduction: The Structural Shift Nobody Expected
In 2015, lab grown diamonds were less than 1% of the diamond market.
In 2024, they were 47.7% of engagement rings sold in the United States.
That's not a trend. That's a structural transformation. And we're only at the beginning.
In this final post — the fifteenth and concluding entry in H&H Jewellery's definitive 15-part Lab Grown Diamonds series — we're stepping back from the details and looking at the big picture. We're exploring where the diamond industry is headed, what the data tells us about the future, and what this means for how we think about diamonds forever.
Because the future of diamonds is not something that will happen to us. It's something we're actively creating, right now, with every choice we make.
The Market Reality: Numbers That Tell a Story
Let's start with data, because data doesn't lie.
2024 Market Share:
- Lab grown diamonds: 47.7% of engagement rings sold
- Lab grown diamonds overall: 21–23% of the total diamond market
- Market value: ~$27–$30 billion
Projected Growth (2025–2030):
- Market size: Growing from $27.95 billion (2025) to $40.8 billion (2030)
- Compound Annual Growth Rate (CAGR): 7.8–11.77%, depending on source
- By 2030, CVD method alone projected at $30.1 billion revenue
Long-Term Projections (2030–2035):
- Global lab grown diamond market: Potentially reaching $108.98 billion by 2035
- Market share of total diamond industry: Projected to exceed 50% by 2035
Demographic Reality:
- 72% of Gen Z prefers lab grown diamonds over mined
- Over 70% of millennials (born 1981–2000) now choose lab grown
- By 2030, Gen Z is expected to represent 30% of all luxury purchases
These numbers are not projections. They're where we already are, with clear trajectories pointing forward.
Trivia 💎: In late 2024, De Beers — the world's largest natural diamond producer and a 130-year-old institution built on mined diamonds — slashed prices by 10–15% in response to lab-grown diamond competition. McKinsey & Co. called lab-grown diamonds "likely the biggest challenge facing diamond producers today." The establishment doesn't dismiss trends. It panics at existential threats.
Why This Transformation Is Irreversible
Several forces are driving this shift, and understanding them matters because they reveal why lab grown diamonds aren't a trend that will fade.
1. Economics That Favour Lab Grown
Lab diamond prices will continue falling as:
- Production capacity scales up (India, China, and other regions rapidly expanding)
- Technology improves (each generation of reactors is more efficient)
- Competition intensifies (more suppliers = more price pressure)
- Supply chains mature (logistics optimise, costs drop)
Meanwhile, mined diamond prices are constrained by geology — you can't make more diamonds appear. The price gap will only widen.
2. Values Alignment for Younger Generations
62% of Gen Z luxury buyers consider ethical sourcing and sustainability essential. This isn't a nice-to-have. This is essential.
Lab grown diamonds align with these values without compromise. You get beauty AND ethics. You get luxury AND responsibility.
As older generations age out of the luxury market and Gen Z takes over (30% of luxury purchases by 2030), values-driven purchasing becomes the industry default.
3. Transparency as a Feature
Younger buyers want to know where things come from. Lab grown diamonds are inherently more transparent:
- Shorter supply chain
- Verifiable facility information
- Documented labour standards
- Energy sourcing can be tracked
Mined diamonds pass through opaque middlemen. Lab diamonds are traceable. In a world where transparency is increasingly demanded, lab diamonds win.
4. The Scarcity Advantage Disappears
Mined diamonds were valuable because of scarcity. But scarcity requires an artificial or natural constraint on supply. Lab diamonds have no natural scarcity constraint — supply can scale infinitely.
Once an entire generation grows up with lab grown diamonds as the default, the "rarity premium" for mined diamonds will largely evaporate. They'll still sell (for their geological origin story), but they'll cease to be the standard.
What the Industry Is Doing in Response
The diamond industry is not sitting passively. Here's how major players are adapting:
Natural Diamond Producers
- Cutting prices (De Beers' 10–15% cut)
- Marketing geological origin stories
- Emphasizing investment value and resale
- Pushing "responsibly mined" certifications
- Competing on heritage and tradition
Jewellery Houses & Retailers
- Expanding lab grown collections
- Launching new lab-grown-specific brands
- Integrating both mined and lab into portfolios
- Emphasising consumer choice
- Focusing on transparency and certification
Technology & Innovation
- CVD reactors becoming more efficient
- Colored lab diamonds expanding
- Larger stones becoming more accessible
- New applications beyond jewelry (industrial, electronics, medical)
- Integration with AI and personalisation
The Three Scenarios for 2030
Based on current trajectories, three scenarios emerge:
Scenario 1: Mainstream Dominance (Most Likely — 70% probability)
Lab grown diamonds become the default choice for buyers under 40. Mined diamonds reposition as premium luxury/investment alternative. Industry splits into two tiers: lab (volume, affordability, ethics) and mined (investment, geological rarity, legacy).
Market outcome: 55–65% lab grown by 2030, 75%+ by 2035.
Scenario 2: Accelerated Transition (Moderate probability — 20%)
Lab grown adoption accelerates faster than predicted due to further technology breakthroughs, environmental crises driving values alignment, or major brand endorsements. Lab grown reaches 70% market share by 2030.
Market outcome: Lab grown dominance by early 2030s.
Scenario 3: Slower Integration (Low probability — 10%)
Mined diamond marketing succeeds in stemming losses. Lab grown remains strong but stabilises at 40–50% of market by 2030. Both coexist as genuine alternatives with differentiated positioning.
Market outcome: Stable two-tier industry, lab growing but not dominant.
Our prediction: Scenario 1 is most likely. The fundamentals are too strong — economics, values alignment, transparency, and demographic shift — for mined diamonds to remain the default.
What Happens to Mined Diamonds?
Mined diamonds don't disappear. They transform.
Repositioning as:
- Investment assets (resale value, geological rarity premium)
- Heritage pieces and heirlooms (emotional value, family legacy)
- Ethical luxury (responsibly mined from certified sources)
- Specialty market (exceptionally large stones, rare colours)
- Geological storytelling (a diamond from a specific moment in Earth's history)
Think of how this mirrors other industries: vinyl records didn't disappear when digital music arrived, they became a specialty market for audiophiles and collectors. Mined diamonds will follow a similar arc.
Projected mined diamond market in 2030:
- Market share: 35–45%
- Price positioning: Premium, investment-focused
- Customer: Buyers who value rarity and geological story over ethics and affordability
- Growth: Flat to declining as percentage of market, but potentially stable in absolute value
The Genuine Unknowns
Several uncertainties could shift these projections:
Technology Breakthroughs
Novel diamond production methods could emerge that are even more efficient, cheaper, or higher-quality than CVD/HPHT. This accelerates lab growth.
Major Certification Changes
If major certification bodies (GIA, IGI) make major changes in how they evaluate or certify diamonds, it could shift market dynamics significantly.
Environmental or Ethical Crisis
A major environmental disaster at mining operations, or exposé about labour practices, could dramatically accelerate shift to lab grown.
Mined Diamond Marketing Success
If heritage diamond marketing effectively repositions mined diamonds as investment/luxury, it might slow lab adoption.
Global Economic Recession
Economic downturns typically suppress luxury spending — affecting both sectors, but potentially benefiting affordable lab diamonds.
What This Means for H&H Jewellery
We're operating in the middle of an industry transformation. Here's our positioning:
We're not choosing a side. We're supporting our customers' values.
- If you want the ethics and affordability of lab grown, we have certified, transparent options.
- If you want the geological story and investment value of mined diamonds, we have responsibly sourced options.
- If you want recycled diamonds with zero additional environmental impact, we can facilitate that.
Our role is to help you make the choice that aligns with your values, not to advocate for one option over another.
The Closing Thought: What This Transformation Reveals
The rise of lab grown diamonds isn't really about diamonds. It's about something deeper.
It's about a generation that doesn't accept the false choice between beauty and ethics. It's about younger people saying: "I want the things I love, but I want them without hidden costs. I want transparency. I want to know where things come from. I want to align my purchases with my values."
Lab grown diamonds simply happened to be the first major luxury category where this values shift could be cleanly executed. The diamond is genuinely identical. The origin is genuinely different. The ethics are genuinely better.
So younger buyers chose differently. And because enough of them did, they reshaped an entire industry in a decade.
That transformation will spread to other categories. It already is — vintage fashion, recycled metals, regenerative agriculture, transparent supply chains. The world is quietly reorganising itself around values alignment.
Lab grown diamonds are just the most visible symbol of this larger shift.
Conclusion: Your Future, Your Choice
The future of diamonds is being written right now, by millions of people making choices aligned with their values.
Every lab grown diamond purchased is a vote for transparency and ethics. Every responsibly mined diamond purchased is a vote for geological rarity and investment potential. Every recycled diamond purchased is a vote for the circular economy.
The industry isn't being forced to transform. It's transforming because millions of people are choosing to. And that choice is reshaping what luxury means — not as something that extracts hidden costs, but as something that delivers beauty without compromise.
At H&H Jewellery, we're here to support whatever choice aligns with your values. Because the future of diamonds isn't determined by any single company or retailer.
It's determined by you.
