CERTIFICATION

Diamond Bayou diamonds are independently verified for quality characteristics and origin. 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 and document each diamond’s cut, color, and clarity. Our diamonds are either verified by the world's most respected gem grading labs including GIA, IGI, HRD, and GCAL. Please contact us to request an electronic copy of a diamond's lab certificate.
