Quick answer: A 2 carat lab grown diamond costs between ₹50,000 and ₹60,000 in India in 2026 for an IGI certified loose stone, depending on the 4Cs. Set into a 14K or 18K gold solitaire ring, the finished piece lands between ₹1,00,000 and ₹1,60,000. That is roughly 90 to 93 percent less than a 2 carat natural diamond of matching quality, which still sells for ₹6 to ₹9.5 lakh. A 2 carat round measures about 8.1mm across, a size difference you notice the moment it is on a hand.
Most people who land on this page are not buying their first diamond. They are stepping up. Maybe from a 1 carat solitaire bought years ago, maybe for a tenth anniversary, maybe because a 2 carat stone finally sits inside a budget that used to buy half of one. Whatever brought you here, the numbers below are real 2026 Indian retail figures, not global averages converted from dollars.
2 Carat Lab Grown Diamond Price in India (2026)
Price moves with quality, and at 2 carats the spread is tighter than most buyers expect. Lab grown supply has matured, so the gap between a good stone and a flawless one is now measured in thousands, not lakhs.
| Quality grade | Colour | Clarity | Price (loose stone) |
|---|---|---|---|
| Entry / smart buy | H to I | VS2 to SI1 | ₹50,000 to ₹53,000 |
| Mid range / most popular | G to H | VS1 to VS2 | ₹53,000 to ₹56,000 |
| Premium | E to F | VVS1 to VVS2 | ₹56,000 to ₹58,000 |
| Top tier | D | IF to VVS1 | ₹58,000 to ₹60,000 |
All figures are for IGI certified, Excellent cut round brilliant stones, loose, before any setting. If you want the full picture across every carat weight, our lab grown diamond price guide for India breaks down 0.30 ct through 5 ct.
What a Finished 2 Carat Piece Costs
Once you add gold and making charges, the arithmetic shifts. The stone stops being the biggest line on the invoice, which surprises almost everyone the first time they see a breakup.
| Piece | Price in India (2026) |
|---|---|
| 2 ct solitaire ring, 14K gold | ₹1,00,000 to ₹1,25,000 |
| 2 ct solitaire ring, 18K gold | ₹1,10,000 to ₹1,35,000 |
| 2 ct solitaire ring, platinum | ₹1,30,000 to ₹1,60,000 |
| 2 ct halo ring, 18K gold | ₹1,25,000 to ₹1,55,000 |
| 2 ct total weight earrings (1 ct each, 18K) | ₹70,000 to ₹1,00,000 |
| 2 ct pendant, 18K gold | ₹85,000 to ₹1,15,000 |
Gold rates move week to week, so treat the setting portion as a live number rather than a fixed one. If you are weighing the metal choice, our comparison of 18K versus 14K gold for diamond rings covers durability, colour and cost.
How Big Is a 2 Carat Lab Grown Diamond?
A 2 carat round brilliant measures roughly 8.1mm across. A 1 carat sits at 6.5mm. On paper that is a 25 percent jump in diameter. On a hand it reads as considerably more than that, because the eye judges the face-up area, and the 2 carat covers close to twice the surface.
| Shape | Approximate size at 2 carats |
|---|---|
| Round brilliant | 8.1mm diameter |
| Oval | 10.0mm × 7.0mm |
| Cushion | 7.5mm × 7.5mm |
| Princess | 7.0mm × 7.0mm |
| Emerald | 9.0mm × 6.5mm |
| Pear | 11.0mm × 7.0mm |
| Marquise | 12.5mm × 6.0mm |
Elongated shapes work harder for you. A marquise or pear at 2 carats spreads further across the finger than a round of identical weight, and usually costs less per carat. If shape is still open, read our guide to oval versus round versus cushion cuts before you commit.
What Actually Decides the Price
Two 2 carat stones sitting side by side can differ by ₹10,000 while looking identical to you across a counter. Here is where that difference comes from, in the order it matters.
1. Cut quality, which outranks everything else
Cut is the only C that is entirely about workmanship rather than the stone itself, and it is the one that decides whether your diamond throws light or sits flat. An Excellent cut carries a 10 to 20 percent premium over Very Good. Pay it. A poorly cut 2 carat looks dull no matter what the certificate says, and no setting rescues it.
2. Colour grade
G and H are the value sweet spot for Indian buyers. In yellow or rose gold especially, the warmth of the metal masks any trace of tint, and you save 10 to 15 percent against D colour. Moving up to D adds roughly ₹5,000 to ₹8,000 on a 2 carat stone for a difference nobody will see on your hand.
3. Clarity grade
VS1 and VS2 are eye clean, meaning no inclusion is visible without magnification. Above VVS2 you are buying a number on paper rather than anything your eye can register. Our full 4Cs guide explains where each grade genuinely stops mattering.
4. Certification
IGI and GIA are the standards worth trusting. Never buy an uncertified 2 carat stone, whatever discount is offered. At this value the certificate is your only independent proof of what you own, and it is what any future buyback or exchange will be assessed against. We cover the detail in what an IGI certificate actually tells you and in our IGI versus GIA versus SGL comparison.
5. Shape
Round brilliant costs the most because cutting one wastes the most rough. Fancy shapes run 10 to 20 percent cheaper at the same weight, and several of them look larger. That is one of the few places in diamond buying where spending less gets you more.
6. Growth method, CVD or HPHT
For a finished, certified 2 carat stone the price difference between the two methods is usually under 5 percent, and neither is more or less of a real diamond. If you are curious about how they differ in practice, our CVD versus HPHT explainer walks through both.
2 Carat Lab Grown vs Natural: The 2026 Price Gap
This is the comparison that ends most people's deliberation.
| Type | Price in India (2026) |
|---|---|
| Natural / mined diamond | ₹6,00,000 to ₹9,50,000 |
| Lab grown diamond | ₹53,000 to ₹56,000 |
| You save | Roughly 90 to 93 percent |
Put that into a real budget. With about ₹1.25 lakh to spend on a finished ring, your two options are a natural solitaire of around 0.40 to 0.50 carats, or a full 2 carat lab grown solitaire in 18K gold. Same hardness, same refractive index, same IGI report format, same sparkle across a dinner table. Four times the stone.
The honest caveat is resale. Neither stone is an investment, but a mined diamond has a longer established secondary market. We set that out plainly in our piece on lab grown diamond resale and buyback, and if you want the wider argument, lab grown versus natural in 2026 covers it in full.
Seven Things Worth Checking Before You Pay
At this price point a single decision swings the bill by tens of thousands. These are the checks we would want a member of our own family to make.
- Verify the certificate yourself. Take the report number and check it on igi.org or gia.edu before any money changes hands. It takes thirty seconds.
- Put cut ahead of colour and clarity. An Excellent cut E colour stone will outshine a Very Good cut D colour stone every single time.
- Stop paying once the difference goes invisible. Past VVS2 clarity and past E colour, you are funding a grading line, not a look.
- Ask for the price broken up. Diamond cost, gold weight, current gold rate, making charges and GST should each appear separately. A seller who will not itemise is telling you something.
- Look seriously at fancy shapes. Oval and cushion stones at 2 carats read 10 to 15 percent larger than round and cost 10 to 20 percent less.
- Buy closer to the source. Large chain markups can add ₹30,000 or more to the same certified stone.
- Get the ring size right before ordering. Resizing a solitaire setting is possible but not free. Our at home ring sizing guide has a printable chart.
One more thing worth knowing if you are buying in India this year: the BIS rules that came into force in 2026 changed how lab grown diamonds must be described and disclosed at the point of sale. Any reputable jeweller will already be compliant, and it gives you a clear standard to hold them to.

Frequently Asked Questions
What is the price of a 2 carat lab grown diamond in India in 2026?
A 2 carat lab grown diamond costs between ₹50,000 and ₹60,000 in India for an IGI certified loose stone, depending on the 4Cs. Set into a 14K or 18K gold solitaire ring, the finished piece ranges from ₹1,00,000 to ₹1,60,000.
How much cheaper is a 2 carat lab grown diamond than a natural one?
Roughly 90 to 93 percent cheaper at matching quality. A natural 2 carat in G colour and VS2 clarity costs ₹6 to ₹9.5 lakh in India. The equivalent lab grown stone costs around ₹53,000 to ₹56,000.
How big is a 2 carat lab grown diamond?
A 2 carat round brilliant measures about 8.1mm in diameter, around 25 percent wider than a 1 carat stone and close to double the face-up area. Elongated shapes such as oval, pear and marquise look larger still at the same weight.
Is a 2 carat lab grown diamond a good choice for an engagement ring?
Yes, and it is now the most common choice among Indian buyers at this size. You get the same brilliance, hardness and certification as a natural 2 carat at a fraction of the cost, which is why so many couples put the difference toward the wedding or a home instead.
What does a 2 carat lab grown diamond ring in 18K gold cost?
A 2 carat solitaire ring in 18K gold at Goenka Jewellers costs between ₹1,10,000 and ₹1,35,000 in 2026. The exact figure depends on the stone's 4Cs and the gold weight of the setting, which is why we itemise both.
Is IGI or GIA better for a lab grown diamond?
Both are reliable. IGI is the practical choice in India because it runs dedicated lab grown grading facilities and its reports are recognised by jewellers and buyers nationwide, which matters if you ever exchange or resell.
Should I choose CVD or HPHT at 2 carats?
CVD is the more common route in India at this size and offers excellent value. For a finished certified stone the difference in price is under 5 percent, and both are chemically and optically identical to mined diamond.
Will a 2 carat lab grown diamond hold its value?
Treat it as jewellery, not an asset. Goenka Jewellers currently offers buyback on lab grown diamonds at 80 percent of retail, but no diamond, mined or grown, is a strong financial investment. If value retention is your priority, gold outperforms both.
Which 2 carat shape looks the biggest?
Marquise, pear and oval. Their elongated outlines spread further across the finger, with a marquise reading up to 15 percent larger than a round of the same carat weight while typically costing 10 to 15 percent less.
Can I get a 2 carat lab grown diamond ring under ₹1.5 lakh in India?
Comfortably. A well cut, IGI certified 2 carat in E colour and VVS2 clarity, set in 18K gold in a clean solitaire mount, sits under ₹1.35 lakh at Goenka Jewellers in 2026. Platinum and halo settings are what push a 2 carat piece past ₹1.5 lakh.
