Lab-Grown Diamonds
Real diamonds. Grown responsibly.
What Are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds — chemically, physically, and optically identical to diamonds mined from the earth. The only difference is where they were created. Instead of forming deep underground over millions of years, they are grown in a controlled laboratory environment in a matter of weeks.
A lab-grown diamond is not a fake diamond, a cubic zirconia, or a simulant. It is a real diamond — with the same carbon crystal structure, the same hardness (10 on the Mohs scale), and the same brilliance.
How Are They Made?
CVD (Chemical Vapour Deposition)
A diamond seed is placed in a chamber filled with carbon-rich gas. The gas is energised, causing carbon atoms to crystallise onto the seed, layer by layer, forming a diamond.
HPHT (High Pressure High Temperature)
A diamond seed is exposed to extreme heat and pressure — replicating the conditions deep within the earth — causing carbon to crystallise into a diamond.

Why We Choose Lab-Grown
Ethical
No mining means no conflict diamonds, no exploited communities, and no environmental destruction.
Affordable
Lab-grown diamonds cost 40–60% less than mined diamonds of the same quality — so you get more for your money.
Identical Quality
Certified by IGI with the same 4C grading as mined diamonds. No compromise on quality.
Common Questions
Are lab-grown diamonds real diamonds?+
Yes. Lab-grown diamonds are 100% real diamonds. They have the same chemical composition (carbon), the same hardness, and the same optical properties as mined diamonds.
Will a lab-grown diamond lose its value?+
Like all diamonds, lab-grown diamonds retain their beauty and durability. As with mined diamonds, resale value depends on quality, size, and market conditions.
Can a jeweller tell the difference?+
Not with the naked eye. Even trained gemologists cannot tell the difference without specialised equipment. IGI certification confirms the diamond's origin.
Do lab-grown diamonds come with certification?+
Yes. Every TATVAAN diamond comes with an IGI certificate confirming its quality and lab-grown origin.
