Lab-Grown Diamond Price Guide India 2026
Lab-Grown Diamond Price Guide India 2026
Why lab-grown diamonds cost 60 to 90 percent less than mined diamonds
Lab-grown diamonds cost 60 to 90 percent less than equivalent mined diamonds of the same grade. This is not because they are inferior. They are chemically, physically, and optically identical to mined diamonds. The price difference exists because lab-grown diamonds are produced in weeks rather than formed over millions of years and extracted through costly, large-scale mining operations. There is no exploration cost, no mining infrastructure, and no complex supply chain. The savings pass directly to the buyer.
Lab-grown diamond price table by carat weight
Nivara prices every lab-grown diamond at one flat rate: ₹50,000 per carat for a VVS clarity, E colour, ideal cut stone. There are no grade tiers and no ranges to decode. Every diamond is IGI certified, with the report number laser inscribed on the girdle.
| Carat weight | Diamond price (INR) | Standard |
|---|---|---|
| 0.30 ct | ₹15,000 | VVS clarity, E colour, round brilliant |
| 0.50 ct | ₹25,000 | VVS clarity, E colour, round brilliant |
| 0.70 ct | ₹35,000 | VVS clarity, E colour, round brilliant |
| 1.00 ct | ₹50,000 | VVS clarity, E colour, round brilliant |
| 1.50 ct | ₹75,000 | VVS clarity, E colour, round brilliant |
| 2.00 ct | ₹1,00,000 | VVS clarity, E colour, round brilliant |
| 3.00 ct | ₹1,50,000 | VVS clarity, E colour, round brilliant |
| 4.00 ct | ₹2,00,000 | VVS clarity, E colour, round brilliant |
These figures are for the diamond stone only. Total jewellery price includes gold (14K or 18K), making charges, and the IGI certificate. At Nivara the diamond itself is always ₹50,000 per carat; the final piece price depends on the setting you choose.
What affects lab-grown diamond price: the 4Cs
Every IGI-certified diamond is priced on the same four criteria used for mined diamonds. Understanding the 4Cs helps you make an informed decision.
Cut
Cut is the most important factor in a diamond's visual quality. It determines how light enters, reflects, and exits the stone. A well-cut diamond with average colour and clarity will outperform a poorly cut stone with superior grades on paper. IGI grades cut as Excellent, Very Good, Good, Fair, or Poor. Every Nivara diamond is an ideal cut, hearts and arrows precise, with no exceptions and no lower tier.
Colour
Colour is graded on a scale from D (colourless) to Z (light yellow). D-F is the colourless range, where the stone appears bright white. G-J is near-colourless and visually indistinguishable from colourless to the naked eye. Every Nivara diamond is E colour, in the colourless range, at every carat weight and at the same rate. Lower colour grades are proportionally less expensive elsewhere, which is why a quote that omits the colour grade is not comparable.
Clarity
Clarity describes the presence and visibility of natural inclusions within the diamond. The scale runs from FL (Flawless) to I3 (heavily included). VS1 and VS2 inclusions are very small and not visible to the naked eye. SI1 stones are also eye-clean in most cases. Every Nivara diamond is VVS clarity, well above the eye clean threshold, so clarity is never the variable you are asked to trade away to reach a budget.
Carat
Carat is the weight of the diamond, not its size. One carat equals 0.2 grams. Price increases non-linearly with carat weight: a 2-carat diamond costs significantly more than twice a 1-carat diamond of the same grade because larger stones are proportionally rarer even in lab-grown production.
How to judge a diamond beyond the price
A diamond is easy to grade on paper and harder to judge in the light. Two stones can carry similar certificates and still not look the same on a hand. Before you compare any two quotes, these are the things worth checking.
- How it handles light. The 4Cs tell you what a diamond is. They do not tell you how it behaves. Brightness, fire (the flashes of colour) and contrast (the crisp balance of light and dark) are what make a stone look alive. A light performance report measures exactly this, beyond the 4Cs, and every Nivara diamond arrives with one.
- The precision of the cut. 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.
- A certificate that matches the stone. Ask for an IGI report whose number is laser inscribed on the girdle, so the paper and the diamond are provably the same object.
- The full standard, named. Ask for clarity, colour and cut by name, not only the carat weight. Comparing carat alone is the most common reason buyers pay more for less.
Every Nivara diamond is chosen by our gemologists and passes 27 quality checks before it is ever set.
Gold karat and price
Lab-grown diamond jewellery is set in either 14K or 18K gold. 18K gold contains a higher proportion of pure gold (75% vs 58.3%) and costs more per gram. Both are BIS-hallmarked at Nivara. White gold and rose gold are priced similarly to yellow gold of the same karat. The choice of gold karat affects the total piece price by approximately 10 to 20 percent depending on the design.
Why IGI certification matters for pricing
An IGI certificate is not a luxury. It is the only way to verify what you are buying. A certified stone has a documented, independently verified grade. An uncertified stone cannot be fairly priced because no third party has confirmed its quality. When comparing prices across retailers, compare only certified stones of identical or comparable grade. A cheaper uncertified 1-carat stone may be a lower grade than a certified 1-carat stone at a higher price. Certification makes the comparison honest.
Every Nivara diamond carries an individual IGI certificate. The certificate number is laser-inscribed on the diamond's girdle for permanent verification.

What a diamond costs at Nivara, per carat
One rate, published, the same for every customer: ₹50,000 per carat for a VVS clarity, E colour, ideal cut diamond, as set out in the rate card above. Carat weight is the only variable in the stone price. There are no grade tiers to decode and no negotiation, because the standard never moves.
These are stone prices. The finished piece adds the setting: the metal weight in 14k or 18k BIS hallmarked gold or platinum, and the making. Both are quoted separately so you can always see which part of the price is the diamond and which part is the craft.
What a solitaire costs in India
A solitaire ring is the clearest way to see how the two halves of the price work. The stone follows the rate card above. The setting depends on how much metal the design carries and how intricate the work is, so a slender four prong band and a wide tapered one holding the same diamond will not cost the same.
Because the diamond in a Nivara solitaire is always VVS and E colour, a 1 carat solitaire here is not competing on grade with a 1 carat solitaire graded two or three steps lower elsewhere. Comparing carat weight alone, without comparing clarity, colour and cut, is the most common mistake buyers make when they compare quotes.

Why the rate does not change by grade
Most jewellers price across a spread of grades. A lower clarity or a warmer colour brings the number down, and the buyer is left deciding how much quality to trade away to reach a budget. Nivara does not run that spread. Every stone is VVS and E, every stone is ideal cut and hearts and arrows precise, every stone passes 27 quality checks, and every stone is IGI certified with the report number laser inscribed on its girdle.
That means the only question left is how large a diamond you want, which is a far easier question to answer honestly than how much quality you are willing to lose.

Frequently asked questions about pricing
What is the price of a lab grown diamond per carat in India?
At Nivara a lab grown diamond is ₹50,000 per carat, published and identical for every customer. Every stone at that rate is VVS clarity, E colour, ideal cut and IGI certified. Carat weight is the only variable in the stone price, so a 0.50 carat diamond is ₹25,000 and a 2 carat diamond is ₹1,00,000. The setting and metal are quoted separately.
How much does a 1 carat lab grown solitaire cost in India?
The diamond in a 1 carat Nivara solitaire is ₹50,000. The finished ring adds the setting, which depends on the metal weight and the design, in 14k or 18k BIS hallmarked gold or platinum. Because every Nivara diamond is VVS clarity and E colour, a 1 carat solitaire here is not being compared like for like against a 1 carat stone graded several steps lower.
Does the price per carat change for larger diamonds?
No. The rate stays ₹50,000 per carat at every weight, so a 3 carat diamond is ₹1,50,000. Many jewellers apply a premium as carat weight rises. Nivara does not, which is why the rate card can be published in full.
What is included in the price of a Nivara piece?
The diamond at ₹50,000 per carat, the metal in 14k or 18k BIS hallmarked gold or platinum, the making, the IGI certificate with the report number laser inscribed on the girdle, and a light performance report grading brightness, fire and contrast. Free insured shipping across India is included, along with lifetime polishing, cleaning, jewellery spa and prong tightening.
Why is there such a big price difference between lab-grown and mined diamonds?
Lab-grown diamonds are produced in weeks using controlled industrial processes. Mined diamonds require deep-earth geological conditions over millions of years, followed by costly extraction, processing, and multi-tier supply chains. The lab-grown price reflects production cost rather than geological scarcity. The diamond you get is chemically identical.
Are cheaper lab-grown diamonds lower quality?
Not inherently. Price is determined by the specific 4Cs grade of each stone, not by whether it is lab-grown or mined. A lab-grown D Flawless 1-carat stone will cost more than a lab-grown I1 1-carat stone. Compare IGI certificate grades, not retail prices, when evaluating quality.
Does the price of lab-grown diamonds change?
Yes. Lab-grown diamond prices have decreased significantly over the past five years as production capacity and efficiency improved. This trend may continue. The prices shown in this guide are approximate as of 2026. Check Nivara's current collection pages for live pricing on specific pieces.
Does the gold type (yellow/white/rose) affect price significantly?
White gold and rose gold are priced similarly to yellow gold of the same karat. The karat (14K vs 18K) is the larger variable. Switching from 14K to 18K typically adds 10 to 20 percent to the metal cost, which affects total piece price.
Is there a difference in price between CVD and HPHT diamonds?
In the current retail market, there is no established or consistent price premium for either growth method. Both CVD and HPHT diamonds of the same IGI-certified grade are priced equivalently. The grade is what determines the price, not the production method.
