It has been said that diamonds are like snowflakes in that no two are alike. Each stone is unique in its beauty and properties with variations in colors, inclusions and trace elements. Using the GIA Standard, we can value diamonds based on Color, Cut, Carat Weight and Clarity.
There are five main features of the diamond’s basic anatomy. They are the table, crown, gridle, pavilion and cutlet and they define your diamond’s shape, size and its overall beauty and brilliance.
Diamond cut refers to how the diamond is physically cut from the rough stone. While nature determines color and clarity, the diamond cutter determines optimal cut for the maximum yield of carat weight. Cut does not refer to shape (round, pear, oval etc.), but rather the symmetry, proportions and polish of a diamond.
This is the main factor in determining the diamond’s overall appearance, based on brilliance (the brightness to the eye created by white light reflections from the surface and inside), fire (the dispersion of light into the colors of the visible spectrum as seen in flashes of color) and scintillation (sparkle when the diamond is in motion).
Cut effects appearance. The better the diamond’s cut, the more brilliant and vibrant and the bigger it looks.
This diamond reflects nearly all of the light that enters it for the greatest possible brilliance and fire.
This diamond reflects almost all the light that enters it allowing for considerable brilliance and fire.
This diamond allows some of light entering it to escape but still offers outstanding brilliance and fire.
This diamond allows much of the light entering to escape and generates minimal fire and brilliance.
This diamond allows most of the light entering it to escape and appears dull.
This is sometimes confused with cut, but it is the outline of the diamond. In order to maximize a stone's material properties, a cutter may choose from various shapes, each with their own aesthetic and cutting requirements.
The most popular shape is the round brilliant. It’s facets and features yield the maximum amount of light, setting the standard for most brilliance and beauty. All other shapes are referred to as “fancy cut” and offer unique beauty and appeal.
Clear diamonds range in color shades. The letter values D, E, and F are almost perfectly clear. Letter values G-Z are more yellowish. The lower the letter, the more yellow you’ll see.
The GIA uses D-to-Z color scale to determine the presence or absence of color in colorless diamonds. Diamonds graded for D, E, and F colors are colorless diamonds. D color diamonds are the highest in the color grading and display unmatched brilliance. E color diamonds contain minute traces of color and display extraordinary brilliance and sparkle. E color diamonds have minute traces of color can be detected only by a trained gemologist. High-quality colorless diamonds were once considered a rarity is now readily available thanks to lab-grown diamond technology.
Diamonds with color grading G, H, I, J in the GIA scale are near colorless diamonds. G-H diamonds contains only minor traces of color almost invisible to an untrained eye. I-J diamonds contain slightly detectable color to the naked eye. The near-colorless diamonds are the most commonly available colorless diamonds in the market.
Diamonds color graded for K, L, M colors in the GIA scale are knowns as faint color diamonds. Contains tint of yellow color noticeable to the naked eye. Despite the presence of color, these diamonds still emit fire and sparkle. Priced considerably less than colorless and near colorless diamonds.
Diamonds with color gradings N, O, P, Q, R are called very light color diamonds. These diamonds contain very noncable tint of pale yellow or brown color. Priced considerably lower than the diamond of higher color grades.
Diamonds color graded S, T, U, V, W, X, Y, Z are known as light color diamonds. These diamonds show clear pale yellow, green or grey color with very little brilliance. Priced substantially lower than higher grades. The diamonds should not be mistaken with fancy color diamond. Hatch Brilliance does not sell light-colored diamonds for the retail market.
Diamonds are sold by the carat (shown as ct.), which is actually a unit of weight, though most think of a carat in terms of size. The word "carat" comes from the "carob" seed, the original unit of measure for diamond traders. Today, a carat is equal to exactly 0.2 grams (about the weight of a paper clip). Carat weight is unrelated to the similar sounding karat, which refers to gold's purity.

When we talk clarity, it’s exactly that: a diamond’s transparency. The sharper the clarity, the better the stone.
