About our-lab-grown diamonds
Our pioneering Lightbox Lab in Portland, Oregon, can grow a 1 carat stone in about two weeks, entirely from 100% renewable wind power.
What's more, our state-of-the-art technology can alter the chemistry of the growing process to create lab-grown diamonds not just in white, but also in blue and pink.
