Frequently Asked Questions
Is a lab-grown diamond a real diamond?
Yes. Lab-grown diamonds are real diamonds — chemically, physically, and optically identical to natural diamonds. They are not simulants like cubic zirconia or moissanite.
What does IGI certification mean?
IGI (International Gemological Institute) is one of the world's leading diamond grading laboratories. An IGI certificate confirms the diamond's 4Cs grade and authenticity.
Which is better — GIA or IGI?
Both are reputable. GIA is considered the gold standard for natural diamonds. IGI is widely used and trusted for lab-grown diamonds and is increasingly accepted globally.
Do lab-grown diamonds hold their value?
The resale market for lab-grown diamonds is still developing. They are best viewed as a purchase for beauty and wearability rather than investment, similar to most fine jewelry.

At a Glance
Both lab-grown and natural diamonds are chemically, physically, and optically identical — pure carbon in a cubic crystal structure. The difference lies in origin, price, and environmental footprint.
Price & Value
Lab-grown diamonds are typically 60–80% less expensive than natural diamonds of equivalent grade. This allows buyers to prioritise size and quality within their budget.
Environmental Impact
Lab-grown diamonds have a significantly lower land and water footprint. When produced using renewable energy, their carbon impact is minimal compared to mined diamonds.
Certification
Both types are certified by leading grading laboratories. Lab-grown diamonds are graded by IGI and GIA using the same 4Cs criteria as natural diamonds.
