The Purchase That Keeps Nagging You
You’re at a jewellery counter in Jayanagar, looking at a solitaire ring that costs ₹2.5 lakh. It’s beautiful. But somewhere in the back of your mind, a question surfaces — where did this actually come from? Who moved the earth, and at what cost, to put this stone in a glass case?
For a growing segment of Bangalore’s urban professionals, that question no longer stays in the back of the mind. It moves to the front of the buying decision. And it’s reshaping what fine jewellery looks like in the city in 2026.
This isn’t a fringe concern. Increasing disposable incomes and changing consumer behaviour are driving urban, value-conscious buyers toward lab-grown diamonds, with the category appealing especially to Millennial and Gen Z buyers. In a city like Bangalore — where sustainability already influences decisions around food sourcing, fashion, and home design — it was only a matter of time before it filtered into jewellery.
What the Numbers Actually Tell Us
In India, lab-grown diamonds are no longer a niche — they are fast becoming the centrepiece of a jewellery revolution. In the first three months of 2025 alone, Indian LGD startups raised over $14 million, marking a 50 percent year-on-year increase compared to the whole of 2024, according to Redseer Strategy Consultants.
The broader market picture confirms this is structural, not cyclical. India’s lab-grown diamond jewellery market is valued at USD 453.7 million in 2026 and is projected to reach USD 1,798.6 million by 2036, with the market expanding at a 14.8% CAGR. And India’s production capacity has already crossed a significant threshold: in fiscal year 2025–26, polished lab-grown diamond exports from India reached 18.80 lakh carats, significantly outpacing polished natural diamond exports of 16 lakh carats for the same period.
These are not vanity metrics. They reflect a genuine consumer shift — one that Bangalore, with its concentration of tech professionals, startup founders, and globally exposed millennials, is leading from the front.
With prices 30–60 per cent lower than mined diamonds and identical certification, sustainability narratives and access to larger stones are compelling younger buyers. “Millennials and Gen Z seek conscious, affordable luxury,” said Ricky Vasandani, CEO and co-founder of Solitario. That framing — conscious luxury, not cheap luxury — is exactly what resonates with the Jayanagar or Koramangala buyer who spends carefully but refuses to compromise on quality.
The Environmental Case, Honestly Stated
Lab-grown diamonds do have an environmental footprint — it would be misleading to suggest otherwise. The CVD and HPHT processes that create them in controlled laboratory settings are energy-intensive, and the carbon impact depends significantly on the energy source used. Lab-grown diamond laboratories still run using a large amount of energy, and the source of that energy has a large impact on the carbon footprint of lab-created diamonds unless it comes from renewable sources such as solar or wind power.
But compared to mined diamonds, the environmental gap is substantial. It is estimated that for every carat of diamond mined, about 160 kilograms of carbon dioxide are released into the atmosphere. One carat of mined diamond equates to nearly 100 square feet of disturbed land and nearly 6,000 pounds of mineral waste, while one carat of lab-grown diamond disrupts just 0.07 square feet of land and results in 1 pound of mineral waste.
Unlike mined diamonds, lab-grown diamonds do not require large-scale land excavation, meaning there is no deforestation, habitat destruction, or significant alteration of landscapes. For Bangalore’s sustainability-oriented buyers — people who already think about their carbon footprint when booking flights or choosing EV vehicles — this math matters. The jewellery on your wrist carries a story, and increasingly, buyers want that story to be a clean one.
The ethical dimension goes beyond carbon. Lab-grown diamonds are guaranteed to be 100% conflict-free, and every step of the process is clear and traceable, so buyers know exactly where their diamond comes from. In a world where supply chain transparency has become a marker of brand trust, that traceability is worth paying attention to.
Why Certification Is the Non-Negotiable
One of the earlier hesitations around lab-grown diamonds — but is it real, and how do I know? — has largely been resolved by the standardisation of third-party certification. In 2026, Indian buyers are choosing lab-grown diamond jewellery with IGI-certified lab-grown stones dominating purchase decisions. Certification has moved from a nice-to-have to a baseline expectation.
IGI’s loose diamond reports clearly identify natural or lab-grown origin and document all aspects of the diamond’s value-setting 4Cs. With IGI-certified diamonds, consumers are assured of quality and authenticity. This is the same grading body that certifies natural diamonds — there’s no separate, lesser standard for lab-grown stones. The rigor is identical.
Buyers in Bangalore have also become noticeably more sophisticated in how they ask questions. Buyers now ask about certification, check sourcing, talk about resale, and compare long-term value — conversations that would have been rare even three years ago. The category has matured, and so has the buyer.
For anyone shopping for lab-grown diamond rings, diamond earrings, or a mangalsutra in Jayanagar or anywhere in Bangalore, ONYA’s entire collection carries IGI certification and BIS-hallmarked gold — the kind of documentation that lets you wear a piece with complete confidence in what you actually own.
The Price Argument Is Real, But It’s Not the Whole Story
Affordability is often the headline when people talk about lab-grown diamonds, and the price difference is genuinely significant. A 1-carat lab-grown diamond in India today costs roughly ₹25,000 to ₹55,000, depending on quality. The same look in a mined stone often costs three to four times more.
But reducing this choice to a budget decision misses what’s actually happening. This emerging trend is not just about affordability — it’s about making a statement. Consumers today, especially the younger generation, are more conscious of the choices they make. Today’s millennials and Gen Z are not just focused on owning beautiful jewellery, but are also thinking about its origins and sustainability.
The more accurate framing is this: lab-grown diamonds let you buy more diamond for the same budget, without the ethical compromise. A Bangalore professional who might have stretched to a 0.5-carat mined solitaire can now wear a 1.5-carat VVS-EF stone in hallmarked gold and still come in well under budget. That’s not a downgrade. That’s a structural advantage.
Younger demographics are driving this market, with Generation Z (aged 18–28) accounting for 51% of the total market value — a 19-percentage-point increase since 2022 — and Millennials contributing an additional 35%. Combined, these younger generations control 86% of the market’s value. These are not buyers who are settling. They are buyers who have done the math and made a deliberate choice.
And the category has gained institutional credibility too. Lab-grown diamonds are edging into mainstream retail, now further catalysed by the entry of Titan, the largest jewellery retailer in the country. When Titan validates a category, the trust signal reaches consumers who were still on the fence.
What Bangalore Buyers Should Actually Look For
Not all lab-grown diamond brands are equivalent, and in a fast-growing market, it pays to be specific about what you’re evaluating. Here are the questions worth asking before any purchase:
IGI or equivalent certification on every stone — not just the headline solitaire, but every diamond in the piece. Certification should be third-party, not self-declared.
BIS hallmarked gold — the metal matters as much as the stone. 14K or 18K gold with BIS hallmarking ensures the gold purity is independently verified.
VVS-EF clarity and colour grade — this is the range where lab-grown diamonds genuinely outshine what most people could afford in natural diamonds. Don’t accept lower grades just because the price seems right.
Exchange and buyback policy — a brand confident in its product offers lifetime exchange and a meaningful buyback percentage. These policies are a proxy for how seriously the brand stands behind what it sells.
Customisation — one of the underrated advantages of lab-grown diamonds is that the production process allows for more design flexibility. If a brand can’t accommodate custom sizing, metal choice, or stone shape, they’re probably not operating at the level the category deserves.
ONYA’s diamond jewellery collection — from solitaire rings to diamond pendants — is built around these exact standards: IGI-certified stones, BIS-hallmarked gold, VVS-EF clarity, 100% lifetime exchange, and 80% buyback. For Bangalore buyers who want the full package without having to verify each element separately, that’s a meaningful starting point.
The shift toward lab-grown diamonds in Bangalore isn’t a trend that needs explaining anymore. It’s a decision that has already been made by a large and growing segment of the city’s most thoughtful buyers. The question now is simply which brand earns that trust.
