MAISON CORINNE
The House of Lab-Grown Diamonds
We are crafting a new standard in conscious luxury. Ethical elegance, redefined.
What we supply
Loose stones only, every one certified by an independent laboratory.
Every shape
Round brilliant, oval, emerald, radiant, princess, pear, cushion, marquise, asscher and heart.
0.30 to 5.00 ct and beyond
Single stones and matched pairs, plus calibrated melee for production runs.
Independently certified
IGI and GIA reports, with the certificate number and document available for every stone.
Consistent supply
Stable access to laboratory production, so repeat orders can be matched with confidence.
Why lab-grown
Chemically, physically and optically identical to mined diamonds — the same carbon, the same hardness, the same fire. Grown rather than extracted, fully traceable, and priced so your margin works harder.
