The popularity of lab grown diamonds in India has increased rapidly in recent years. Modern buyers now want larger, more brilliant diamonds without paying the premium associated with mined stones. As a result, lab-grown diamonds have become a preferred choice for engagement rings, anniversary gifts, and fine jewellery.
At JJ Jewellers, we believe every customer deserves complete transparency before making a purchase. This guide explains everything you need to know about lab-grown diamonds, certification, pricing, and buying tips for 2026.
Are Lab Grown Diamonds in India Real Diamonds?
This is the most common question buyers ask.
The simple answer is yes.
Lab-grown diamonds have the same chemical composition, crystal structure, hardness, brilliance, and sparkle as natural diamonds. The only difference lies in their origin.
Natural diamonds form beneath the earth over billions of years. Lab-grown diamonds develop inside controlled laboratories using advanced technology. Therefore, they offer the same beauty and durability while remaining significantly more affordable.
Even trained gemologists require specialised equipment to identify the difference. To the naked eye, both diamonds appear identical.
Understanding CVD and HPHT Lab Grown Diamonds in India
When exploring lab grown diamonds in India, you will often come across two manufacturing methods.
HPHT Diamonds
HPHT stands for High Pressure High Temperature.
This process recreates the natural conditions under which diamonds form underground. While HPHT diamonds are genuine diamonds, some stones may display slight colour variations depending on their formation process.
CVD Diamonds
CVD stands for Chemical Vapour Deposition.
This advanced process grows diamonds layer by layer from carbon-rich gases. Many buyers prefer CVD diamonds because they often achieve superior colour grades and excellent clarity.
For solitaire rings and statement jewellery, CVD diamonds are frequently considered an excellent option.
Why Certification Matters When Buying Lab Diamonds
Certification is just as important as the diamond itself.
The International Gemological Institute (IGI) is among the most trusted certification authorities for lab-grown diamonds worldwide.
An IGI certificate confirms:
- Cut quality
- Colour grade
- Clarity grade
- Carat weight
- Growth method (CVD or HPHT)
- Any post-growth treatments
Without certification, buyers cannot accurately verify the diamond’s quality.
Additionally, always check whether the certificate number is laser-inscribed on the diamond girdle. This inscription connects the physical stone to the certification report.

What Are Lab Grown Diamond Prices in India in 2026?
One of the biggest advantages of lab-grown diamonds is affordability.
Approximate price ranges include:
| Carat Weight | Quality Grade | Price Range |
|---|---|---|
| 0.50 Carat | F / VS1 | ₹15,000 – ₹30,000 |
| 1.00 Carat | E / VS2 | ₹40,000 – ₹90,000 |
| 1.50 Carat | D / SI1 | ₹70,000 – ₹1,50,000 |
| 2.00 Carat | F / VVS2 | ₹1,20,000 – ₹2,50,000 |
A comparable mined diamond often costs several times more.
However, buyers should never select a diamond solely because of a low price. Certification, quality, and transparency must always accompany affordability.
Why More Indian Buyers Are Choosing Lab-Grown Diamonds
Consumer preferences continue to evolve.
Today’s buyers appreciate lab-grown diamonds for several reasons:
Better Value
Customers can purchase larger stones or higher quality grades within the same budget.
Ethical Sourcing
Lab-grown diamonds avoid mining-related environmental disruption and conflict concerns.
Modern Luxury
Many younger buyers view lab-grown diamonds as a smart and informed purchase rather than a compromise.
However, buyers should understand that resale values may differ from natural diamonds due to changing market supply dynamics.
