D, E, F:
The
grades D, E, and F represent the higher end of clarity and are considered the
best quality. D holds the highest rank, displaying no visible color blemishes
even under careful scrutiny. However, diamonds in these grades are known for
their rarity, brilliance, and higher cost. According to GIA standards, diamonds
in grades D, E, and F are categorized as colorless.
G, H, I,
J:
The
grades G, H, I, and J fall just below the previous category in terms of
clarity. Diamonds in this range are described as near colorless, exhibiting
only a slight color tinge that is not easily noticeable except under intense
inspection. They offer excellent value as they come close in quality to the D,
E, and F grades but are slightly more affordable. These diamonds are relatively
easier to find than the higher-grade categories. To an untrained eye, the
stones appear brilliant, with only a slight difference compared to a master
stone of the higher grade class.
K, L, M:
The next
grade class is K, L, and M, which displays a slightly faint yellow hue. This
light coloration is noticeable to an untrained eye and distinguishes them more
significantly from the former two grade classes. Good-cut diamonds in this
grade class can be obtained at a better bargain.
N to R:
The N,
O, P, Q, and R categories are characterized by their pronounced yellow hue and
are termed very light yellow to slightly light brown. Due to the noticeable hue, these diamonds are considered lower in quality. Setting these diamonds in yellow gold mounts can be a good option to tone down the
yellow color. Despite their lower quality, they are more affordable and easily
accessible.
S to Z:
The S to
Z category represents the lower end of the grading system. Diamonds in this
range have a light yellow to light brown coloration. They are easily accessible
and affordable, as their quality is not considered high-end. S-graded diamonds
exhibit a yellowish tinge under the naked eye, while the Z category appears
light brown.
Notably,
it is incorrect to assume that lower-grade diamonds have negligible worth. With
a well-cut and appropriately proportioned weight in carats, lower-grade
diamonds can offer great value, especially if they rank higher in polish,
symmetry, and finish. Pairing them with a high-quality gold mount can further
enhance their appearance.
