Emerald Cut 5.5ct F VS2 CVD Diamond Lab Grown Diamond IGI Certificate

Own timeless elegance with a clear conscience. Messi Jewelry’s 5.5-carat emerald-cut CVD lab-grown diamond is cultivated in a closed-loop, solar-powered reactor that emits up to 75 % less CO₂ than traditional mining and requires zero earth displacement, water-table disruption, or habitat loss. Each stone is forged from high-purity carbon atoms, layer by layer, eliminating the social and ecological shadow cast by open-pit or alluvial extraction. The result is an IGI-certified diamond with identical optical, chemical, and physical properties to its mined counterpart—minus the environmental baggage. From Stockholm sustainability pledges to California carbon-neutral weddings, this emerald-cut masterpiece delivers the icy-white F color and VS2 clarity demanded by discerning designers while honoring the planet every step of the way.

What is a Lab Grown Diamond?

A lab grown diamond is one that has been manufactured in a controlled laboratory environment. Using the popular methods of Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT), scientists can now create diamonds that optically look like earth-mined diamonds, contain the same chemical and physical attributes and even receive certification through the Gemological Institute of America (GIA) and International Gemological Institute (IGI).
