Learn About Diamonds
A diamond certificate or grading report provides an expert opinion on the quality of the diamond and is provided by an independent gemology lab. Trained gemologists with specialized equipment measure the weight and dimensions of the diamond and assess quality characteristics such as cut, color, and clarity. Brilliant Earth diamonds are certified by the world’s leading gem grading labs including GIA, AGS, IGI, and Gemscan. Please contact us to request an electronic copy of a diamond's lab certificate.

All Brilliant Earth diamonds come with a certificate guaranteeing their ethical origin. Our diamonds are tracked throughout their chain of custody to ensure that they are mined, cut, and polished with respect for people and the environment. This ensures that they are not tainted by violence and that they are produced in accordance with the highest labor and environmental standards.
Many retailers claim that they do not carry conflict diamonds – defined as diamonds financing rebel groups attempting to overthrow national governments. However, very few retailers have auditing processes in place to guarantee that their diamonds are wholly free from violence and that they are not tainted by child labor, worker exploitation, and environmental devastation. At Brilliant Earth, we provide more than a conflict free guarantee. We guarantee that our diamonds originate from socially and environmentally responsible sources.
Brilliant Earth guarantees the diamond you choose is pure in origin and reflects your values.
