Diamond Colour Grading Scale

As we specialize in selling fine diamond jewellery at Steven Stone we sell diamonds graded from D to J. The diagram below shows the different colour grades and their slightly yellow tint as the grades go down. White Diamond Colour Grades D, E & F – These are the rarest and most expensive diamonds due to their complete colourless appearance. Within these grades the diamond looks colourless face-down and face-up. G & H – These diamonds are near colourless and still an extremely desirable and slightly more affordable colour grade. The diamonds may have a slight tint of yellow face down update `wp_posts` set `post_content` = only to be seen through a jeweller’s 10x loupe) I & J – These diamonds have a slight yellow tint, which may be a little more noticeable. So to make it simple the closer to D you go, the more expensive and rare the diamond will be. There is no real different to the naked eye with D, E, F, G and H colour grades, whereas I and J may have very slightly, noticeable hints of yellow colour.
