Physically and chemically identical to a mined diamond — only its origin differs. Every stone is IGI or GIA certified.

A lab-grown diamond is a real diamond. Physically, chemically and optically identical to a mined diamond, it has the same brilliance, the same purity and the same hardness (10 on the Mohs scale). Only its origin differs: it is grown in a laboratory in a matter of weeks, rather than over millions of years underground.

To the eye, in the hand and even under a gemologist's loupe, nothing distinguishes it from a mined diamond — it is certified by the same independent laboratories (IGI, GIA) against the same 4C criteria: carat, color, clarity and cut. The difference lies elsewhere: in your conscience, and in the price.

• Up to 40% less expensive for strictly equal quality: for the same budget, a larger and purer diamond.
• Ethical and conflict-free: no mining, no gray areas about the stone's origin.
• A smaller footprint: up to 85% lower carbon footprint than an equivalent mined diamond.
• 100% traceable and certified: every stone comes with its IGI / GIA certificate.

Choosing a lab-grown diamond at Laveran means refusing to choose between beauty and conscience: you give exactly the same absolute brilliance, with complete peace of mind.
