Diamonds are valued by how closely they approach colorlessness \u2013 the less color, the higher their value. (The exception to this is fancy color diamonds, such as pinks and blues, which lie outside this color range.) Most diamonds found in jewelry stores run from colorless to near-colorless, with slight hints of yellow or brown.<br><\/p>\n\n\n\n<p>GIA\u2019s color-grading scale for diamonds is the industry standard. The scale begins with the letter D, representing colorless, and continues with increasing presence of color to the letter Z, or light yellow or brown. Each letter grade has a clearly defined range of color appearance. Diamonds are color-graded by comparing them to stones of known color under controlled lighting and precise viewing conditions.<br><\/p>\n\n\n\n<p>Many of these color distinctions are so subtle as to be invisible to the untrained eye. But these slight differences make a very big difference in diamond quality and price.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"780\" height=\"440\" src=\"https:\/\/christosimanoglou.gr\/wp\/wp-content\/uploads\/2020\/08\/01.jpg\" alt=\"\" class=\"wp-image-2824\" srcset=\"https:\/\/christosimanoglou.gr\/wp2\/wp-content\/uploads\/2020\/08\/01.jpg 780w, https:\/\/christosimanoglou.gr\/wp2\/wp-content\/uploads\/2020\/08\/01-600x338.jpg 600w, https:\/\/christosimanoglou.gr\/wp2\/wp-content\/uploads\/2020\/08\/01-64x36.jpg 64w, https:\/\/christosimanoglou.gr\/wp2\/wp-content\/uploads\/2020\/08\/01-300x169.jpg 300w, https:\/\/christosimanoglou.gr\/wp2\/wp-content\/uploads\/2020\/08\/01-768x433.jpg 768w\" sizes=\"auto, (max-width: 780px) 100vw, 780px\" \/><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">WHY DOES THE GIA COLOR GRADING SYSTEM START AT D?<\/h4>\n\n\n\n<p>Before GIA developed the D-Z Color Grading Scale, a variety of other systems were loosely applied. These included letters of the alphabet (A, B and C, with multiple A\u2019s for the best stones), Arabic (0, 1, 2, 3) and Roman (I, II, III) numerals, and descriptions such as \u201cgem blue\u201d or \u201cblue white.\u201d The result of all these grading systems was inconsistency and inaccuracy. Because the creators of the GIA Color Scale wanted to start fresh, without any association with earlier systems, they chose to start with the letter D\u2014a letter grade normally not associated with top quality.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Diamond color is all about what you can\u2019t see.
