In India, a 1 carat IGI-certified lab grown diamond typically costs between ₹25,000 and ₹60,000 depending on cut quality, colour, clarity, and whether it is CVD or HPHT grown. This is 60–80% less than an equivalent mined diamond. A complete piece of lab grown diamond jewellery - ring, pendant, or earrings - starts from around ₹15,000 and scales with carat weight, metal choice, and brand.
The Price Conversation Nobody Is Having Honestly
Most lab grown diamond brands in India advertise two things: affordability and sustainability. What they rarely do is tell you exactly what you should expect to pay, why prices vary so dramatically, and how to know whether you're getting genuine value.
This guide does exactly that. We're going to give you the real numbers, explain what drives them, and introduce a framing that we think makes more sense than price-per-carat for most buyers in India: cost per wear.
Why Lab Grown Diamonds Cost Less
The price difference between lab grown and mined diamonds isn't about quality - it's about supply chain. A mined diamond requires geological processes that take billions of years, extraction from deep in the earth, and a global distribution network before it reaches a retailer. A lab grown diamond is created in a controlled environment over weeks and has a far shorter, more transparent supply chain.
The result: a lab grown diamond is chemically, physically, and optically identical to a mined diamond. The GIA and IGI certify both using identical criteria. The price difference reflects production economics, not quality.

What Affects the Price of a Lab Grown Diamond?
The 4 Cs Still Apply
Cut: Excellent or Ideal cut grades maximise light return and brilliance. This is the one C you should never compromise on. Expect a 15–25% premium for Excellent cut vs. Good cut.
Colour: D–F (colourless) stones command the highest prices. G–H (near colourless) are visually equivalent to the naked eye in most settings and represent the best value.
Clarity: VS1–VS2 is the sweet spot — inclusions are invisible without magnification. SI1 can also be eye-clean and offers better value at a given budget.
Carat: Larger stones carry exponentially higher prices. A 1ct diamond costs significantly more than two 0.5ct diamonds of equivalent quality due to the rarity of larger stones, even in lab grown production.
CVD vs. HPHT: Does It Matter?
Both methods produce Type IIa diamonds — the purest category. CVD (Chemical Vapour Deposition) and HPHT (High Pressure High Temperature) both produce equally valid certified stones. Price differences between the two are minimal at the retail level.
Certification: Non-Negotiable
Always buy a certified lab grown diamond. IGI is the most widely accepted certification for lab grown diamonds in India and is recognised by all major jewellers and insurers. GIA also carries significant weight. Uncertified stones have no verifiable provenance and should be avoided regardless of price.
The Framework That Changes Everything: Cost Per Wear
Price-per-carat is the jewellery industry's default framing. We think cost-per-wear is more honest — and more useful.
If you buy a pair of IGI-certified lab grown diamond studs for ₹22,000 and wear them every day for five years, your cost per wear is approximately:
₹22,000 ÷ 1,825 days = ₹12 per day
For context: a cup of specialty coffee in any Indian metro costs more than that. A mined diamond equivalent would cost ₹85,000–₹1,00,000 — and most women would wear it far less often. The cost-per-wear gap is dramatic.
How to Buy Lab Grown Diamond Jewellery in India: A Checklist
-
Certification — Insist on IGI or GIA for every stone above 0.25ct. The certificate number should be laser-inscribed on the girdle and verifiable online.
-
Metal purity — Look for BIS hallmarked gold. 18K gold is 75% pure; 14K is 58.3%.
-
Return and exchange policy — Minimum 30-day return window and lifetime exchange are industry standards.
-
Transparent pricing — Diamond price should be separable from making charges and metal price.
-
After-care — Ask about prong checking, cleaning services, and jewellery insurance.
What You Get at Different Price Points
Under ₹20,000: Delicate pendants, small studs (0.15–0.25ct tw), thin diamond bands. A beautiful entry point — a single piece you'll reach for every day.
₹20,000–₹50,000: The most versatile range. 0.5ct stud earrings, solitaire pendants, thin eternity bands. This is where most of Mija's everyday collection lives.
₹50,000–₹1,50,000: Statement pieces — tennis bracelets, larger solitaires, drop earrings. For building a considered collection over time.
Above ₹1,50,000: Bespoke and high jewellery territory. Still dramatically more accessible than the mined diamond equivalent.
A Note on Resale Value
We want to be transparent about this because most brands aren't. Lab grown diamonds have lower secondary market resale value than mined diamonds - the market for resale is still developing in India. If you are purchasing jewellery primarily as a financial investment, mined diamonds or gold remain more established stores of value.
If you're purchasing jewellery to wear - and to enjoy - lab grown diamonds offer unparalleled value per rupee. The choice is a function of your priorities, and only you can make it.
The best price for a lab grown diamond is the one that lets you wear it every day without a second thought. Browse Mija's collection - every piece is IGI-certified, BIS hallmarked, and priced for real life.
FAQ SECTION — PEOPLE ALSO ASK
How much does a 1 carat lab grown diamond cost in India in 2026?
A 1 carat IGI-certified lab grown diamond costs approximately ₹25,000–₹60,000 in India depending on cut, colour, and clarity grade. The equivalent mined diamond would typically cost ₹1,00,000–₹2,50,000 or more, making lab grown stones 60–80% more accessible.
Are lab grown diamonds cheaper than natural diamonds in India?
Yes, consistently. Lab grown diamonds cost 60–80% less than mined diamonds of equivalent grading. The price gap has been stable and is expected to remain as production continues to scale.
Do lab grown diamond prices vary by shape?
Yes. Round brilliants are the most expensive shape due to highest demand and greatest material waste during cutting. Oval, cushion, pear, and emerald cuts typically offer better value per carat.
What is the best carat size for everyday diamond jewellery in India?
For daily wear, 0.3–0.5ct total weight for earrings and 0.25–0.5ct for a pendant offers the ideal balance of visible sparkle and practical wearability.
Is IGI certification important when buying lab grown diamonds in India?
Yes, it is non-negotiable. IGI certification verifies the stone's authenticity, grading, and origin. It is also required for insurance purposes and makes the piece easier to exchange or upgrade in the future.
Will lab grown diamond prices decrease further in India?
Production costs have been declining steadily. While further decreases are possible, the retail jewellery experience — design, craftsmanship, metal, certification, and service — holds its value. Prices for quality finished pieces are unlikely to collapse significantly.
