A lab-grown diamond engagement ring is an engagement ring that features a man-made, laboratory-created diamond instead of a mined diamond. The only difference between the two diamonds is the point of origin. Because a lab-grown diamond did not have to be mined, the engagement ring is free from human and environmental toll. A VRAI created lab-grown diamond engagement ring goes even farther, however. We convert greenhouse gas into sustainably created diamonds in a zero-emission, hydropowered foundry.
