The Diamond Color Grading System

As mentioned earlier, one of the Four C’s of diamond grading is “Color.” Color in reference to diamonds, ironically enough, refers to the lack of color found in diamonds. The mark of a perfect diamond are Colorless qualities. This means there are no yellow hues or tints found in the diamond, and the diamond stone radiates a perfect transparent clean hue. The G.I.A (Gemological Institute of America) came up with the jewelry industry standard of grading diamonds on a letter scale from D to Z. The three top grades for Colorless diamonds are D, E, and F.  The next range of diamonds that are close to Colorless as possible are referred to as Near Colorless. These grades include G, H, I, and J. G grade diamonds are some of the best, and at the top of the Near Colorless category. G Si1 diamonds will indicate a diamond that is Near Colorless, and are one of the best Si1 diamonds on the market. Following G Si1 diamonds will be H Si1 diamonds. Si clarity H color diamond also falls in the range of Near Colorless, but are graded second to G Si1 diamonds. If you’re considering is an H Si1 diamond worth buying, in comparison to G Si1 diamond, the answer yes. Both Si1 diamond color grades are top quality, and fall under Near Colorless. But it’s important to know the diamond color grading scale when considering G Si1 diamond and H Si1 diamond.
