Yes, it really is accurate. Colorless diamonds are commonly more steeply-priced than diamonds with seen color due to the fact they're rarer and feature a higher degree of transparency and sparkle. Colorless diamonds are the maximum enormously prized on the Gemological Institute of America's (GIA) D-to-Z diamond color grading scale, with the highest grade being D, which signifies a totally colorless diamond. The call for for colorless diamonds is better due to their perceived beauty and status, making them extra precious and, therefore, more expensive. but, there are many other elements that could have an effect on a diamond's fee, which include its clarity, cut, carat weight, and typical rarity, so prices can nonetheless vary widely.
