GIA color grade from D (completely colorless), Z (a light yellow or brown). Colorless diamond, but I think that actually complete a colorless diamond is extremely rare. Most diamonds used in jewelry has a slightly pale yellow or brown color. Master set the color grade of the diamond (diamonds) and seats based on the color will be determined. Alphabet of each letter grade represents a range of colors, the color in the eyes of some degree is the basis for ttuineunga Fluorescence (Fluorescence): Some diamonds emit visible light when exposed to ultraviolet light, which fluorescence is not a factor in determining color or clarity grade. Fluorescent on GIA grading reports, however, the fluorescence intensity of the reaction and the depiction is provided with additional differentiating features.

GIA clarity grade is Flawless (Flawless) I3 is in the range of 11 Diamond has no inclusions formed by the tremendous heat and pressure, so diamonds are extremely rare. These characteristics is a byproduct in the formation process of a diamond, gemologists distinguish from natural diamonds hapseongseok and similar seats, and it is helpful to distinguish between each diamond.

The Excellent GIA cut grade on the Poor. D to Z color range of the standard round brilliant diamonds on the GIA cut grade. Lack the light on the surface of the polished diamond's beauty Higo, how much light enters the diamond internal, and are associated with complex interactions, such as any form of light into our eyes as backtracking. Three characteristics that result looks stunning appearance.

Brightness (Brightness) is a blend of all the white light that is reflected from the surface and interior of a diamond. Diamonds in the light like a flame of fire blazing Fire (Fire) is a phenomenon. Ssintil migration (Scintillation) is a flash of light, the diamond, the light source, or that appear when the observer moves. Proportions of the diamond polishing (polishing ratio) that influence a diamond's beauty and overall appearance of the light affects. Balanced proportions and decent in a good diamond polished looks best Brightness, Fire, and ssintil migration effects as much light as possible through interaction.

Display are the carat weight of the diamond, 1 carat 0.2 g (g).
Diamond carat is divided into 100 points.
0.75 carat = 75 points, 1/2 carat = 50 points

UV ultraviolet fluorescence response is called for short. 4C is not included in, but the difference is noted in the appraisal leave, and the price, regardless of the reaction, called Strong Blue diamonds represent the "Blue Diamond" is also referred to as. 4C does not contain as much as a standard to judge the value of a diamond does not have, Strong Blue a whole accounts for about 20% of the diamonds, but rather in terms of scarcity that can be more ear.
