    Having cut and polished the majority of the twenty largest diamonds discovered this century, Graff revealed a 302.37-carat square emerald-cut diamond just last year, which was lauded for being the highest clarity, highest colour diamond ever graded by GIA. Without doubt, Graff possesses unparalleled technological prowess in the art of cutting and polishing, which brings out the utmost beauty of natural gems, particularly diamonds. This emerald-cut diamond is no exception.
