Walk into any jewellery conversation in India today, and lab grown diamonds come up almost as often as gold rate updates. But between certification terms, price ranges, and regulatory changes, most buyers still aren't sure what actually separates a well-made piece from a risky one.
Here's what this guide covers: what lab grown diamonds actually are, what they cost in India right now, how certification works, and what to check before you buy.
What Are Lab Grown Diamonds?
Lab grown diamonds are crystallized carbon formed in a controlled lab environment instead of underground, sharing the same chemical structure, hardness, and optical brilliance as mined diamonds. The difference lies entirely in where and how the stone formed.
The Science, Explained Simply
Two growth methods produce lab grown diamonds today: CVD (chemical vapor deposition) and HPHT (high pressure, high temperature), both replicating the conditions that form diamonds naturally, just in a lab setting. Neither method changes what the finished stone actually is.
● Made of pure crystallized carbon, identical to mined stones
● Rated 10 on the Mohs hardness scale, the highest possible
● Grown using CVD or HPHT methods over several weeks
● Visually and chemically indistinguishable without lab equipment
● Legally classified as real diamonds under global grading standards
● Distinct from simulants like cubic zirconia or moissanite
Understanding this origin story matters, because it's the foundation everything else - pricing, certification, and value - is built on.
How Much Do Lab Grown Diamonds Cost in India?
A 1-carat IGI-certified lab grown diamond in India currently ranges between ₹25,000 and ₹55,000 for the stone alone, depending on cut, color, and clarity. Setting it into hallmarked gold adds metal and craftsmanship costs on top.
What Actually Drives the Price
Price isn't just about the stone - cut quality, gold purity, and design complexity all factor in, the same way they do with any fine jewellery purchase. Understanding this breakdown helps you compare quotes properly instead of judging by sticker price alone.

Are Lab Grown Diamonds Certified in India?
Yes, reputable lab grown diamonds sold in India carry certification from labs like IGI or SGL, which grade the stone's cut, color, clarity, and carat weight. As of January 2026, India's Bureau of Indian Standards also enforces IS 19469:2025, a national standard requiring clear disclosure of a diamond's origin at the point of sale.
What This Regulation Actually Means for You
This standard exists to protect buyers from ambiguous terminology or undisclosed stone origin - a real gap the industry needed to close. It means any seller offering a diamond, mined or lab-grown, must state that origin clearly, not leave it implied.
● IGI certification is the most widely used for lab grown diamonds
● SGL is common in India and remains a reliable alternative
● Certificates state growth method: CVD or HPHT
● BIS IS 19469:2025 mandates clear origin disclosure at sale
● A missing certificate should be treated as a dealbreaker
● Certificates make future resale or exchange far more straightforward
Together, certification and regulation give Indian buyers a documented way to know exactly what they're purchasing, not just a jeweller's word for it.
What Should You Check Before Buying Lab Grown Diamond Jewellery in India?
Check four things before you buy: the certification report, the gold hallmark and HUID number, the exact making charges, and the seller's return or exchange policy. Skipping any one of these is where most buyer disappointment comes from later.
Verify the HUID number on your gold setting through the BIS CARE app before finalizing a purchase, since this confirms the metal purity independently of what the seller states. Ask for an itemized quote that separates diamond cost, gold value, and making charges, so you understand exactly what you're paying for. A seller confident in their sourcing will readily walk you through certification and hallmarking without hesitation - that willingness is itself a useful signal.
Which Lab Grown Diamond Jewellery Should You Choose?
The right piece depends on how often you'll wear it and what occasion it needs to serve - solitaire studs and pendants for everyday wear, statement pieces for events, and layered sets for weddings. Thinking through use first narrows the decision considerably.
Everyday pieces like studs or a minimalist pendant work well as a first lab grown diamond purchase, since lighter designs suit daily wear without feeling like an event piece. For weddings or milestone occasions, bridal jewellery leans into heavier, more detailed craftsmanship. Rings, whether for engagements or everyday wear, remain the most requested category, largely because a lab grown stone lets buyers choose a noticeably larger center diamond within the same budget.
Is Lab Grown Diamond Jewellery a Good Long-Term Choice?
For everyday wear and lasting brilliance, yes - a lab grown diamond holds its hardness, clarity, and shine indefinitely, just like a mined one. For resale value specifically, it's worth knowing that lab grown diamonds typically resell for less than mined diamonds, and neither should be treated as a financial investment.
This isn't a downside unique to lab grown stones - it reflects how the broader diamond resale market works. What you're buying is a genuine diamond you'll wear and enjoy for years, backed by real certification, not an appreciating asset.
Frequently Asked Questions
Are lab grown diamonds real diamonds?
Yes. They share the same chemical composition, hardness, and optical properties as mined diamonds. The only difference is where the stone formed - underground versus in a controlled lab setting.
Is IGI certification reliable for lab grown diamonds in India?
Yes. IGI is the most widely used certifier for lab grown diamonds in India, with reports that are easy to verify and specifically designed to grade lab-grown stones.
What does BIS IS 19469:2025 mean for buyers?
It requires sellers to clearly disclose a diamond's origin at the point of sale, giving Indian buyers a regulatory backing beyond just the certificate itself.
How much gold purity should I look for in lab grown diamond jewellery?
Look for 14kt or 18kt BIS-hallmarked gold, and verify the HUID number through the BIS CARE app before purchase.
Do lab grown diamonds come with a warranty in India?
Reputable brands typically offer a warranty covering manufacturing defects, along with a buyback or exchange policy. Always confirm the exact terms before buying.
Making a Confident Choice
Buying lab grown diamond jewellery in India comes down to three things: understanding what you're actually purchasing, verifying it through proper certification and hallmarking, and choosing a design that fits how you'll actually wear it. The regulatory groundwork is finally catching up to the category, which makes this a genuinely well-documented purchase, not a leap of faith.
