There is no set and industry wide accepted standard of cut quality in an Emerald Cut diamond or any other Fancy Shape diamond. However, Mr. David Atlas of Accredited Gem Appraisers has determined a range of values that generally speaking accurately depict cut quality in Fancy Shape Diamonds. These ranges of values are not absolute standards but are excellent guidelines.
