Frequently Asked Questions

Lab Grown Diamonds
What are lab-grown diamonds? Are they real diamonds?

Absolutely. Lab-grown diamonds are real diamonds—identical to mined diamonds in their physical, chemical, and optical structure. The only difference is their origin: they are grown in a modern, controlled environment rather than formed underground.
How are lab-grown diamonds made?

Lab-grown diamonds are created using two methods: CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature). While both produce real diamonds, CVD is widely recognized for delivering higher clarity, better color consistency, and a cleaner growth environment.

At Diamond Soirée, we exclusively supply CVD-grown diamonds — never HPHT — ensuring each stone meets the highest standards of purity, brilliance, and quality. CVD diamonds grow layer by layer from a tiny diamond seed, allowing exceptional control over the final diamond’s beauty and structure, all without the environmental impact of mining.
Can you tell the difference between lab-grown and natural diamonds?

No, not with the naked eye. Even trained gemologists require specialized equipment to distinguish between the two.
Are lab-grown diamonds graded the same way as natural ones?

Yes. They are graded on the same 4Cs — Cut, Color, Clarity, and Carat — by reputable gem labs.
Do lab-grown diamonds last as long as natural diamonds?

Absolutely. They share the same durability and hardness, making them perfect for a lifetime of wear.

Quality & Certification
Are your lab-grown diamonds certified? By whom?

Yes. Our diamonds are certified by respected laboratories such as IGI and GIA, ensuring transparency and quality.
What’s the difference between IGI and GIA certifications?

Both labs follow strict grading standards. IGI is widely known for grading lab-grown diamonds, while GIA is the world’s most established authority in gem grading. Both provide reliable, internationally recognized certificates.

  • Color: Exclusively D, E, F, and G — the finest, whitest color grades.
