There's a question we hear almost every day at Goenka Jewellers - from a young couple in Kolkata picking their first solitaire, to a Delhi professional gifting a milestone anniversary piece.
"Should I go for a lab grown diamond or a natural one?"
It's not a simple question. And anyone who tells you it is - probably doesn't know diamonds well enough.
We've spent years working closely with IGI-certified lab grown diamonds, seen how the Indian jewellery market has shifted, and spoken with hundreds of real buyers about what actually matters to them. So here's our honest, experience-backed answer for 2026.
First - Let's Clear the Biggest Myth
A lab grown diamond is not a fake diamond. It is not cubic zirconia. It is not moissanite.
A lab grown diamond has the exact same chemical composition, crystal structure, optical properties, and hardness as a mined diamond. The only difference? It was grown in a controlled laboratory environment in weeks - rather than formed over billions of years beneath the Earth's surface.
In fact, even gemologists with decades of experience cannot tell them apart with the naked eye. Only specialised equipment can distinguish the two.
That's the starting point. Now let's go deeper.
Natural vs Lab Grown Diamond: An Honest Side-by-Side
1. Price - The Most Talked-About Difference
This is where the conversation gets real for most Indian buyers.
A natural diamond of 1 carat, good cut, VS clarity, and G colour can easily cost ₹3–5 lakh or more. The same specifications in a lab grown diamond will typically cost 50–70% less.
That's not a small saving - that's the difference between a modest stone and a stunning 2-carat solitaire for the same budget.
For lab grown diamond India buyers, especially, this is transformational. Families who once had to compromise on size, clarity, or design now have genuine freedom of choice.
2. Quality - Are They Truly Equal?
Yes — and in some ways, lab grown diamonds can actually be more consistent in quality. Since they're grown under precise conditions, inclusions and colour inconsistencies that naturally occur during geological formation are far less common at the same price point.
Every diamond at Goenka Jewellers comes with IGI (International Gemological Institute) certification - the gold standard for grading both mined and lab grown diamonds. This means you know exactly what you're buying: the carat, colour, cut, and clarity are fully documented and verified.
3. Ethics & Sustainability - The New Generation Cares
In 2026, this is no longer a niche concern. A significant share of Indian millennial and Gen Z buyers are actively asking about the origin of what they wear.
Natural diamond mining has well-documented environmental and human rights concerns - large-scale land disruption, significant carbon emissions, and in certain regions, troubling labour conditions.
Lab grown diamonds use considerably fewer resources, produce a substantially smaller carbon footprint, and carry no conflict supply-chain concerns. For buyers who want their jewellery to align with their values, the choice is clear.
4. Resale Value - Let's Be Honest
This is the part where we believe in giving you the complete picture rather than the comfortable answer.
Natural diamonds have historically held better resale value. The secondary market for mined stones is established and more liquid.
Lab grown diamonds are newer to the resale ecosystem. Prices have dropped as production has scaled, which has affected resale value in the short term.
However — here's what most jewellers won't tell you - very few people actually sell their diamond jewellery. Most pieces are passed down, repurposed, or kept as heirlooms. The resale question is emotionally weighted but practically less relevant for the majority of buyers.
At Goenka Jewellers, we also offer a 100% buyback policy on our pieces — which means you're protected regardless of the broader resale market.
5. Emotional Value - This One is Personal
Some people feel a deep emotional connection to the idea of a stone formed over billions of years in the Earth's mantle. That's completely valid. Sentiment is real, and we respect it.
Others feel just as strongly that a diamond created through scientific brilliance — optically perfect, ethically sourced, and more accessible — carries its own profound meaning. Especially when it allows them to buy something significantly more beautiful for the same money.
There is no wrong answer here. The right diamond is the one that feels right to you.
So, Which Is Winning in 2026?
In India, the market has spoken clearly. Lab grown diamonds are growing at an extraordinary pace, particularly in metros like Kolkata, Delhi, Mumbai, and Bengaluru.
Here's why:
- Indian buyers are value-conscious and quality-driven. Lab grown diamonds deliver both.
- The IGI certification removes the trust barrier that held early buyers back.
- Younger buyers are reshaping what "luxury" means — it's no longer just about rarity, it's about intelligence, ethics, and personal meaning.
- Bridal and gifting segments are seeing massive uptake as families realise they can get a dramatically larger, cleaner stone for the same budget.
Natural diamonds still have their place — particularly in ultra-premium heirloom pieces or for buyers who specifically want the geological origin story. But in terms of market momentum, buyer preference, and sheer value delivered, lab grown diamonds are unquestionably leading in 2026.

We don't just sell diamonds. We help people make the right decision for their lives, their budgets, and their values.
Frequently Asked Questions
Is a lab grown diamond real?
Yes. A lab grown diamond is chemically, physically, and optically identical to a mined diamond. It is graded by the same gemological institutes using the same 4C standards.
Are lab grown diamonds cheaper in India?
Yes — significantly. Lab-grown diamond prices in India are typically 50–70% lower than those of equivalent natural diamonds, making fine diamond jewellery accessible to a much wider segment of buyers.
Will lab grown diamonds last forever?
Absolutely. They have the same hardness (10 on the Mohs scale) and durability as natural diamonds. A lab grown diamond will last generations.
Can I tell the difference just by looking?
No. Even trained gemologists cannot distinguish a lab grown diamond from a natural one without specialised equipment.
