What Is a Lab Grown Diamond?
A lab grown diamond is a real diamond created in a laboratory using advanced technology that replicates the natural diamond formation process. These diamonds have the same chemical, physical, and optical properties as mined diamonds.
Lab diamonds are produced using two main methods:
HPHT (High Pressure High Temperature)
This method recreates the extreme pressure and temperature conditions found deep inside the Earth.
CVD (Chemical Vapor Deposition)
In this process, carbon-rich gases are used to grow a diamond crystal layer by layer.
Both methods produce real diamonds that are identical to natural diamonds.

Factors That Affect the Price of a 1 Carat Lab Grown Diamond
1. Cut Quality
The cut of a diamond determines how well it reflects light.
Common cut grades include:
- Excellent
- Very Good
- Good
- Fair
Diamonds with an Excellent cut are more expensive because they produce better brilliance and sparkle.
2. Diamond Color
Diamond color is graded from D to Z.
| Grade | Quality |
|---|---|
| D–F | Colorless |
| G–J | Near Colorless |
| K–M | Faint Color |
A D or E color diamond is rare and therefore more expensive.
Most buyers choose G–H color diamonds because they offer great value and still look very white.
3. Diamond Clarity
Clarity measures the presence of internal inclusions or imperfections.
Common clarity grades include:
- FL (Flawless)
- VVS1 / VVS2
- VS1 / VS2
- SI1 / SI2
Higher clarity diamonds cost more, but many inclusions are not visible to the naked eye, especially in VS or SI grades.
4. Diamond Shape
The shape of a diamond also affects the price.
Popular shapes include:
- Round
- Oval
- Cushion
- Princess
- Emerald
- Pear
Round diamonds are usually the most expensive because they require more precision during cutting and waste more raw diamond material.
5. Certification
Always buy a certified lab grown diamond.
Popular certification labs include:
- IGI (International Gemological Institute)
- GIA (Gemological Institute of America)
Certification ensures that the diamond has been professionally graded for:
- Cut
- Color
- Clarity
- Carat weight
Certified diamonds are more trustworthy and easier to resell.
Lab Grown Diamonds vs Natural Diamonds Price
One of the biggest reasons people choose lab diamonds is the price difference.
| Diamond Type | Average Price (1 Carat) |
|---|---|
| Natural Diamond | ₹3,00,000 – ₹6,00,000 |
| Lab Grown Diamond | ₹40,000 – ₹1,50,000 |
As you can see, lab diamonds provide huge cost savings without compromising beauty or durability.
