A certificate from an independent grading laboratory is like a diamond’s fingerprint. It provides a reliable assessment of the key criteria that define that stone, such as its carat weight, measurements, cut, shape, and other vital determinants of the diamond’s rarity and quality. We rely on the reputation and authority carried by reports from the GIA and EGL USA to certify all of our loose diamonds.
GIA’s diamond grading reports are the industry standard; each stone is reviewed by up to six gemologists before a final verdict on its key characteristics is reached. GIA produces two types of reports: a full report for diamonds one-carat and higher, and a dossier for diamonds under one-carat (a dossier is like a full report minus the detailed plotting of the stone’s inclusions).
EGL offers full reports as well and has pioneered services that disclose treatments and detects lab-grown diamonds.
