Two names dominate that conversation: the GIA (Gemological Institute of America) and the AGS (American Gem Society). Both are respected. Both were, in fact, founded by the same man. And as of 2022, their relationship changed in a way most buying guides still haven't caught up with. This guide breaks down exactly how GIA and AGS compare \u2014 and where IGI fits in \u2014 so you can read any certificate with confidence, whether you're buying one engagement ring or sourcing certified stones for a jewelry line.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"wd-negative-gap elementor-element elementor-element-813d9c9 e-flex e-con-boxed e-con e-parent\" data-id=\"813d9c9\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-20462c5 elementor-widget elementor-widget-heading\" data-id=\"20462c5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">What Is GIA Certification?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-298442b elementor-widget elementor-widget-image\" data-id=\"298442b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/www.provencejewellery.com\/wp-content\/uploads\/elementor\/thumbs\/gia-certification-report-sample-rpd20y010h7iid0gh0wjh5dkuy7rzvetaxoofsj72w.webp\" title=\"gia certification report sample\" alt=\"gia certification report sample\" loading=\"lazy\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9ed27f0 elementor-widget elementor-widget-wd_text_block\" data-id=\"9ed27f0\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"wd_text_block.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"wd-text-block reset-last-child text-left\">\n\t\t\t\n\t\t\t<p>The Gemological Institute of America was founded in 1931 by Robert M.

AGS Laboratories, the grading arm, wasn't established until the mid-1990s, when gemologist Peter Yantzer (formerly of GIA) built a scientifically rigorous, light-performance-based system for grading diamond cut. That system used a 0\u201310 numerical scale, with 0 (\u201cIdeal\u201d) representing the top grade \u2014 a sharper, more technical alternative to GIA's descriptor-based grades.<\/p><ul><li style=\"list-style-type: none;\"><ul><li>Cut: 0 (Ideal) through 10 (Poor), numerical scale<\/li><li>Color: 0.0 (colorless) through 10.0 (light yellow), mirroring GIA's D\u2013Z<\/li><li>Clarity: 0 (Flawless) through 10 (I3), mirroring GIA's FL\u2013I3<\/li><\/ul><\/li><\/ul><p>AGS built its reputation on being the first lab to rigorously quantify light performance \u2014 brightness, contrast, and light leakage \u2014 rather than relying on proportion tables alone.

Because it measured proportions to a finer degree of precision than GIA \u2014 rather than rounding to the nearest half-percent or half-degree \u2014 an AGS Ideal grade represented a narrower, more exacting quality band.<\/p><h3><strong><b>How GIA Grades Cut<\/b><\/strong><\/h3><p>GIA's cut grade also considers three factors: face-up appearance (brightness, fire, scintillation), design (weight ratio and durability), and craftsmanship (polish and facet alignment precision). GIA currently offers a full cut grade only for round brilliant diamonds; fancy shapes (oval, cushion, pear, and others) receive polish and symmetry grades but not an overall cut grade \u2014 a gap AGS's system was built to fill for several fancy shapes before AGS Labs closed.<\/p><h3><strong><b>The Practical Upshot<\/b><\/strong><\/h3><p>An AGS Ideal (0) and a GIA Excellent are very closely aligned in practice, but they aren't identical: AGS effectively split GIA's single \u201cExcellent\u201d tier into two finer bands, so some GIA Excellent stones would not have qualified for AGS's top Ideal grade, while others would. For most buyers under normal lighting, the visual difference between a strong GIA Excellent and an AGS Ideal is imperceptible \u2014 the gap matters most to buyers chasing the very top percentile of light performance.<\/p><p>Regardless of which lab graded a round brilliant diamond, these proportion ranges are a reliable quality benchmark to check on the report itself:<\/p><ul><li style=\"list-style-type: none;\"><ul><li>Table: 54% \u2013 60%<\/li><li>Depth: 59% \u2013 63%<\/li><li>Crown angle: 33\u00b0 \u2013 35\u00b0<\/li><\/ul><\/li><\/ul>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"wd-negative-gap elementor-element elementor-element-06a78db e-flex e-con-boxed e-con e-parent\" data-id=\"06a78db\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-f59e783 elementor-widget elementor-widget-heading\" data-id=\"f59e783\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Trade Value and Resale: What the Data Shows<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0af05e4 elementor-widget elementor-widget-wd_text_block\" data-id=\"0af05e4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"wd_text_block.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"wd-text-block reset-last-child text-left\">\n\t\t\t\n\t\t\t<p>Certification quality also affects how a diamond trades on the wholesale market.
