Their diamond graduate programs (<strong>Diamontology<\/strong>, <strong>Diamond Grading Essentials<\/strong>&#8230;) are the most sought after credentials around. Their diplomas hold the highest admiration and esteem. Recognized and praised, <strong>there is no achievement higher<\/strong>. Nothing compares. They are <strong>the cream of the crop<\/strong>.<\/p>\n<p><h2>2) The most advanced equipment in the industry<\/h2>\n<p>\nGIA uses the <strong>most advanced equipment<\/strong> made by man to grade diamonds with. Much of this equipment <strong>they&#8217;ve created themselves<\/strong>. As far back as <strong>1930<\/strong>, GIA has been using and perfecting the detecting system with specialized tools such as&#8230;<\/p>\n<p><strong><\/p>\n<ul>\n<li>GIA Instrument Microscopes<\/li>\n<li>GIA Diamond Check<\/li>\n<li>DL Scopes<\/li>\n<li>Daylight Equivalent Fluorescent Light Sources<\/li>\n<li>Color Filters<\/li>\n<li>X-Rays; Fluorescent, Diffractive Meters<\/li>\n<li>Refractometer Lamps<\/li>\n<li>Chemical Analysis<\/li>\n<li>Dichroscopes<\/li>\n<li>Diffraction Grating Spectroscopes<\/li>\n<li>Imaging Photomicrography<\/li>\n<li>GIA Diamond Dock<\/li>\n<li>Handheld Loupes<\/li>\n<li>Atomic Structure Analysis<\/li>\n<li>Color Grading Master Sets<\/li>\n<li>Diamond View<\/li>\n<li>Research Tools and Reference Books<\/li>\n<\/ul>\n<p><\/strong><\/p>\n<p>\nAll things that can <strong>increase accuracy<\/strong> and give GIA the upper hand.<\/p>\n<p><h2>3) Triple redundancy<\/h2>\n<p>\nGIA doesn&#8217;t grade diamonds alone. They actually have <strong>a triple check system<\/strong> called &#8220;<strong>triple redundancy<\/strong>&#8220;. This means that 3 diamontologists evaluate and grade each and every stone. They then arrive on a single expert grade that <strong>best represents<\/strong> that diamond.<\/p>\n<p>\nThis redundancy assures there are <strong>zero disputes<\/strong> with the results or the report. So when GIA says that a diamond is SI1, E&#8230; <strong>They mean it!<\/strong><\/p>\n<p><h2>4) Rounding down<\/h2>\n<p>\nMany jewelers who grade diamonds in house (<strong>themselves<\/strong>) round up (called &#8220;<a href=\"https:\/\/www.jewelry-secrets.com\/Blog\/grade-bumping-diamonds\/\">Grade Bumping<\/a>&#8220;). Meaning, if a diamond is <strong>questionable<\/strong>, or <strong>borderline <\/strong>between two grades (like it could be an I1, or it could be an SI2), many places and people would call it the <strong>higher grade<\/strong>. This makes the diamond <strong>sound <\/strong>better, <strong>sell <\/strong>better, <strong>makes them more money<\/strong>, and is totally legit with the <strong>FTC<\/strong> (You can be off as much as one whole grade; because grading is <strong>subjective and opinionated<\/strong>).<\/p>\n<p>\nBut when GIA grades a diamond that&#8217;s borderline, <strong>they will always grade lower<\/strong>;<\/p>\n<p><h2>Rounding down!<\/h2>\n<p>\nThis means that the grade put on a diamond is <strong>at least that, or better<\/strong>. This is why GIA is so <strong>trusted<\/strong>. No one disagrees with their grades or stance. <strong>There&#8217;s never a doubt or a question<\/strong>.<\/p>\n<p>\nGIA leads. Their certificates (<strong>Diamond Reports<\/strong>) are the best there are. And it&#8217;s also the best way to be assured of the grades you&#8217;re buying (<strong>Not getting ripped off<\/strong>).<\/p>\n<p>\n<strong>With GIA, an SI1, E, is just that!<\/strong><\/p>\n<p>\nBut with other lax grading companies (like <strong>EGL, IGI<\/strong>&#8230;), an SI1, E, really could be an I1, F instead (also meaning, <strong>you paid too much!<\/strong>)<\/p>\n<p><h2>Compare the prices below:<\/h2>\n<table>\n<tr>\n<td style=\"background-color:#87c1fc\" valign=\"top\"><strong>CARAT, CLARITY, COLOR, CUT, POL, SYM, FLUOR<\/strong><\/td>\n<td style=\"background-color:#87c1fc\" valign=\"top\"><strong>PRICE<\/strong><\/td>\n<td style=\"background-color:#87c1fc\" valign=\"top\"><strong>VIEW<\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"background-color:#FFFFFF\" valign=\"top\"><strong>1.00, I1, F, EX, EX, EX, NONE<\/strong><\/td>\n<td style=\"background-color:#FFFFFF\" valign=\"top\"><strong>$3,500<\/strong><\/td>\n<td style=\"background-color:#FFFFFF\" valign=\"top\"><a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/www.jamesallen.com\/loose-diamonds\/round-cut\/?CaratFrom=1&#038;CaratTo=30&#038;Color=F&#038;Clarity=I1&#038;Cut=Ideal,Excellent,TrueHearts&#038;PriceFrom=&#038;PriceTo=&#038;ViewsOptions=Images&#038;advancedParameter=CaratSliderBottom&#038;showAdvanced=show&#038;Shape=round&#038;Polish=EX,ID&#038;Symmetry=EX,ID&#038;Lab=GIA&#038;Flour=None,Negligible&#038;DepthFrom=45&#038;DepthTo=80&#038;TableFrom=40&#038;TableTo=83?a_aid=JSDG\">VIEW<\/a><\/td>\n<\/tr>\n<tr>\n<td style=\"background-color:#cbe3ff\" valign=\"top\"><strong>1.00, SI2, E, EX, EX, EX, NONE<\/strong><\/td>\n<td style=\"background-color:#cbe3ff\" valign=\"top\"><strong>$5,400<\/strong><\/td>\n<td style=\"background-color:#cbe3ff\" valign=\"top\"><a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/www.jamesallen.com\/loose-diamonds\/round-cut\/?CaratFrom=1&#038;CaratTo=30&#038;Color=E&#038;Clarity=SI2&#038;Cut=Ideal,Excellent,TrueHearts&#038;PriceFrom=&#038;PriceTo=&#038;ViewsOptions=Images&#038;advancedParameter=CaratSliderBottom&#038;showAdvanced=show&#038;Shape=round&#038;Polish=EX,ID&#038;Symmetry=EX,ID&#038;Lab=GIA&#038;Flour=None,Negligible&#038;DepthFrom=45&#038;DepthTo=80&#038;TableFrom=40&#038;TableTo=83?a_aid=JSDG\">VIEW<\/a><\/td>\n<\/tr>\n<\/table>\n<p><h2>Big difference in price!<\/h2>\n<p>\nSo if you want accuracy, <strong>buy GIA!<\/strong><\/p>\n<p>\nBut if you want to chance it, <strong>roll the dice and gamble<\/strong>, then go with any report and <strong>cross your fingers<\/strong>&#8230;<\/p>\n<p><h2>Me, I&#8217;ll stick with GIA!<\/h2>\n<p>\nAnd I&#8217;m sure if you compared quality and diamonds&#8230; <strong>You would too!<\/strong><\/p>\n<p>\nJust ask any jeweler, anywhere in the world; &#8220;Who&#8217;s the best diamond grading company?&#8221;.
