A 2, 3 or 4 carat lab-grown diamond ring is priced from the diamond up. At Nivara a VVS E diamond is ₹50,000 per carat, so the stone in a 2 carat ring is ₹1,00,000, a 3 carat ₹1,50,000, and a 4 carat ₹2,00,000. The setting and metal are additional, and the diamond meets the same standard at every carat weight.
How much does a 2, 3 or 4 carat lab-grown diamond ring cost in India?
A larger diamond is now within reach without giving up anything that makes a diamond worth wearing. Lab-grown is why. The size grows, and the standard does not move. Here is how a Nivara diamond is priced.
Our pricing is simple, and it is the same for everyone.
A Nivara VVS E diamond is ₹50,000 per carat.
That is the standard you have just read, priced plainly. Not a figure that starts low and climbs at the counter, and not a range that shifts by who is asking. The diamond you are shown is the diamond you take home.
Applied to the sizes buyers ask for most, that comes to:
| Carat weight | Nivara VVS E diamond (stone only) |
|---|---|
| 1.00 carat | ₹50,000 |
| 2.00 carat | ₹1,00,000 |
| 3.00 carat | ₹1,50,000 |
| 4.00 carat | ₹2,00,000 |
Figures are for the diamond only and current for 2026. The setting and metal, BIS-hallmarked 14k or 18k gold or platinum, are additional, so the final ring price depends on the setting you choose. For the full picture across every carat, see our guide to lab-grown diamond prices in India.
How a bigger diamond reads on the hand
Carat is weight, not width, but the two track closely in a round brilliant cut. A well cut stone carries its weight face-up, where it shows. This is the finger presence buyers are really asking about.
| Carat weight | Approximate face-up diameter (round brilliant) |
|---|---|
| 1.00 carat | 6.5mm |
| 2.00 carat | 8.1mm |
| 3.00 carat | 9.3mm |
| 4.00 carat | 10.2mm |
Approximate for a round brilliant. An IGI certificate confirms a specific stone's measurements. Elongated shapes such as oval, marquise and pear look larger still for the same weight, because they carry their size in length.
At 2 carats a diamond commands the hand and still wears every day. At 3 and 4 carats it becomes the statement, the stone people notice first. For a ring built around a single large diamond, see our lab-grown diamond solitaires and statement-making rings.
The same standard at every carat weight
A bigger diamond hides nothing. Every facet, every degree of colour, every trace of an inclusion is easier to see at size. That is exactly why the standard cannot soften as the carat climbs. At Nivara it does not.
At Nivara there is one standard, and every diamond meets it.
Every Nivara diamond is VVS in clarity and E in colour. Every one is an ideal cut, hearts and arrows precise. Every one is chosen by our gemologists and passes 27 quality checks before it is ever set. And every one arrives with its own light performance report, so its brightness, fire, and contrast are not described to you. They are measured for you.
We wear diamonds to feel good, and to stand out. That should never come with a compromise. So we do not make one.
Whether you choose 1 carat or 4, the diamond is VVS E, ideal cut, and hearts and arrows precise, and it arrives with its own light performance report. A larger stone simply gives that standard more room to show.
What to look for in a big-carat lab-grown diamond
At size, the things that matter most matter more. These are worth looking for in any diamond, and they are not negotiable in a large one.
A diamond is easy to grade on paper and harder to judge in the light. Before you choose one, these are the things worth looking for.
- How it handles light. The 4Cs tell you what a diamond is. They do not tell you how it behaves on your hand. A diamond's real beauty is its brightness, its fire (the flashes of colour), and its contrast (the crisp balance of light and dark that makes it look alive). A light performance report measures exactly this, beyond the 4Cs.
- Cut, and the precision of it. Cut is where a diamond earns its light. Look for an ideal cut, and for hearts and arrows, a pattern that appears only when a diamond is cut with near perfect symmetry. It is the difference between a stone that sparkles and one that merely sits there.
- Colour and clarity you can actually name. Ask precisely what you are getting, not only the carat.
- A certificate that matches the stone. Look for an IGI report whose number is laser inscribed on the diamond itself, so the paper and the stone are one and the same.
Know these, and you can judge any diamond you are shown.
What makes a Nivara diamond stand out
What makes a Nivara diamond stand out is that it is chosen to. Our gemologists select for the stones that catch the eye across a room, the ones that look brilliant on a hand, not merely correct on a report.
And a Nivara diamond is cared for, for life. Every piece comes with lifetime polishing, cleaning, and our jewellery spa. We tighten prongs and maintain your piece for as long as you own it. Should you ever wish to, you can exchange it at full value, or return it to us through our lifetime buyback at 100% gold value and 85% diamond value.
A diamond chosen to stand out, kept brilliant for a lifetime, and always worth returning to. That is what a Nivara diamond is.
Many big-carat rings are engagement rings. If that is the occasion, our guide to lab-grown diamond engagement rings covers settings and styles, and you can browse the full engagement rings collection.
