It details standardized industry metrics for evaluating a diamond's shape, color, clarity, cut proportions, and carat weight. The chart outlines the color spectrum from colorless (D-F) to light (S-Z), categorizes clarity levels from internally flawless (I.F.) to included (I-2), and lists common diamond shapes including round, emerald, marquise, and princess. Additionally, it highlights essential technical specifications for assessing cut quality, such as table width, crown height, pavilion depth, and girdle diameter, while noting the significance of light return and symmetry features like hearts and arrows. As an authoritative resource from the International Gemological Institute, this document serves as a standardized benchmark for professionals and consumers to understand the complex grading factors that determine a diamond's value and aesthetic appeal in the global jewelry market.",{"@graph":63,"@context":118},[64,80,101],{"@type":65,"itemListElement":66},"BreadcrumbList",[67,71,74,77],{"item":68,"name":69,"@type":70,"position":9},"https://docshare.wps.com","Home","ListItem",{"item":72,"name":10,"@type":70,"position":73},"https://docshare.wps.com/template/",2,{"item":75,"name":51,"@type":70,"position":76},"https://docshare.wps.com/template/general/",3,{"item":78,"name":59,"@type":70,"position":79},"https://docshare.wps.com/template/diamond-grading-chart-igi/563427/",4,{"url":78,"name":59,"@type":81,"image":82,"author":87,"headline":59,"publisher":90,"fileFormat":93,"inLanguage":57,"description":61,"dateModified":94,"datePublished":95,"encodingFormat":93,"isAccessibleForFree":96,"interactionStatistic":97},"DigitalDocument",{"url":83,"@type":84,"width":85,"height":86},"https://docshare.wps.com/thumbnails/diamond-grading-chart-igi/563427.png","ImageObject",442,249,{"name":88,"@type":89},"GGG","Person",{"url":68,"name":91,"@type":92},"DocShare","Organization","application/pdf","2026-10-27","2026-10-12",true,{"@type":98,"interactionType":99,"userInteractionCount":8},"InteractionCounter",{"@type":100},"ViewAction",{"@type":102,"mainEntity":103},"FAQPage",[104,110,114],{"name":105,"@type":106,"acceptedAnswer":107},"What are the main categories used for diamond grading in this chart?","Question",{"text":108,"@type":109},"The primary grading categories are shape, color, clarity, cut, and carat.","Answer",{"name":111,"@type":106,"acceptedAnswer":112},"How is diamond color classified according to the IGI chart?",{"text":113,"@type":109},"Diamond color is classified on a scale from D-F (Colorless), G-J (Near Colorless), K-M (Slightly Tinted), N-R (Very Light), to S-Z (Light).",{"name":115,"@type":106,"acceptedAnswer":116},"What technical factors determine the cut of a diamond?",{"text":117,"@type":109},"Key technical factors include total depth, table width, crown height, pavilion depth, girdle diameter, culet, and light return, as well as the presence of hearts and arrows.","https://schema.org",{"og:url":78,"og:type":120,"og:title":59,"og:site_name":91,"og:description":61},"article",{"robots":122,"canonical":78},"index,follow",{"doc_id":124,"site_id":56},563427,1792113465,{"code":4,"msg":5,"data":127},{"doc_id":124,"user_id":128,"nickname":88,"user_avatar":129,"doc_module":9,"category_id":50,"category_name":51,"doc_title":59,"doc_description":61,"doc_content":130,"file_id":131,"file_url":132,"file_type":133,"file_size":134,"view_count":8,"is_deleted":4,"is_public":9,"is_downloadable":9,"audit_status":9,"page_count":9,"language":135,"language_code":57,"site_id":56,"html_lang":57,"table_of_contents":136,"faqs":137,"seo_title":138,"seo_description":61,"update_tm":139,"read_time":4},962093532725,"https://ap-avatar.wpscdn.com/davatar_276721f389ce27ea32af1340a28f341c","DIAMOND GRADING CHART  \nSHAPE  \nRound Emerald Marquise Heart Pear Cushion Radiant Oval Princess  \nCOLOR  \nD-F  \nColorless  \nG-J  \nNear Colorless  \nK-M  \nSlightly Tinted  \nN-R  \nVery Light  \nS-Z  \nLight  \nCLARITY  \nI.
