D
Deep Cut Cut too Deep
Cut refers to the technician and finish after cutting diamond cutting edge Angle in proportion to the parts. When the rate of diamonds from the waist down too deep, the light will be near or at the bottom of the outflow, lose luster. Diamond value also is getting low.
Dimond master set color stone
One sets of the calibration, the standard type diamond cut diamond color samples, representatives from high to low in turn the color of the continuous level.
Dimond light color lights
At 5500 k ~ 5500 k color temperature range of fluorescent lamp.
Diameter of the Diameter
Diamond waist diameter circular horizontal plane, which is called the minimum diameter, maximum 1/2 diameter (maximum + minimum diameter) value is referred to as the average diameter.
Dispersion Dispersion
Into the diamond light, make internal reflection according to the different aspect Angle, the distribution of the light reflection to produce rainbow in seven colors, known as dispersion.
Diamond, Diamond
Is mainly composed of carbon and other axis (cube) natural mineral crystal system. Mohs hardness, 10 (+ / - 0.01) 3.52 g/cm3 density, refractive index of 2.417, 0.044 dispersion.
Diamond grading Diamond grading
From color (see colour, clarity, clarity, cut (cut), and quality (carat) four aspects to hierarchies of diamond, hereinafter referred to as 4 c grade.
Diameter of the Diameter
Diamond waist diameter circular horizontal plane, which is called the minimum diameter, maximum 1/2 diameter (maximum + minimum diameter) value is referred to as the average diameter.

F
Feather Feather grain
Diamond internal or extend to internal parts.
Finish to modify/polishing
Diamond cutting and polishing the surface smooth degree. If grinding craft excellent, the diamond has excellent polishing.
Fire Fire chroma
Refers to the diamond break down the intensity of the light reflected from 7 colour spectrum. Is closely related to the percentage of cutters, and symmetry.
Fluorescence intensity of Fluorescence degree
Diamond under longwave violet light irradiation of visible light intensity levels. Part of the diamond under ultraviolet light, will send the white, yellow, or blue light, this characteristic is called fluorescence effect. General amateurs usually don't notice. Fluorspar light effect is not the measure of quality of diamond is just a feature of the diamond. And personal preferences are different. According to diamond in China under the long wave ultraviolet luminous intensity is divided into "strong", ""," weak "and" nothing "four levels. Abroad is usually divided into negligible, none, inert, abbreviation, blue, strong blue six levels.
Called Facets cut
