The color level of the diamond is strictly divided. Under normal circumstances, the diamonds we are talking about refer to the colorless diamond, that is, the more transparent the color, the higher the diamond. In fact, there are many colored diamonds, and the color of diamonds can be divided into several types. The color classification of diamonds 1. The color of natural diamond -colorless The colorlessness in diamonds can be divided into two series, one is colorless transparency, close to colorless, and the other is light yellow. This diamond is the best among all diamonds. In the color classification of colorless diamonds, the top color is D color, and it is arranged to Z in order. We only say that from D to J's color level, D-F is colorless colorless. In the level, G-J is a near-color level, and it is basically not meaningful from K to the bottom, but the precepts below the K color will be very beautiful. Of course, the higher the diamonds, the price is more expensive. 2, the color of natural diamonds -color color diamonds are divided into: yellow diamonds, red diamonds, blue diamonds, pink diamonds, green diamonds, black diamonds. Each color diamond is a rare treasure. The main cause of color diamonds is the color that changes the particles in colorless diamonds. Different changes produce different colors, so the less the color and the higher the value. . The difference between their color is mainly due to the absorption of different trace elements, resulting in different colors. When the yellow diamond is formed, the nitrogen atom replaces some carbon atoms in the diamond crystal, and the diamonds begin to absorb blue and purple light, so the diamond appears yellow. In the process of formation, blue diamonds absorb trace boron elements, and they appear into sky blue. The red diamond is the diamond in the process of formation, and the lattice structure is distorted, making it red. Green diamonds are due to the natural radiation that changes the lattice structure, resulting in green. These colored diamonds are also treasures in diamonds and are expensive. Among them, red diamonds are the most precious. The color diamond is best M diamond ring color mainly depends on the color level of the diamond, and the color of the diamond is divided into white diamonds and color diamonds. We usually use the ring to propose or get married. The color level of the white diamond from D color to M color, D color is the highest color grade of diamond, completely colorless state; E color is colorless, only professional appraisal experts can detect trace colors; although F color is also colorless, although it is also colorless , But you can still detect a small amount of color; G to H color is close to colorless. When this level of diamonds and D colors and E color diamonds make close contrasts, you will find a slight color; It is easier to detect mild colors than the previous level; K to M color can obviously see a darker color. In fact, the color of the diamond is good. This depends on personal preferences. In addition, the quality of a diamond is judged. In addition to the color, everyone should pay attention to the clarity, carat weight and cutting.
A single score from ordinary diamonds, with color levels, is divided into D, E, F, G, H, I-J, K-L, M, N-O, P-R, S-Z. Most gem -level diamond colors are between colorless and light yellow. Below is the level diagram corresponding to the color of the diamond. D level: completely colorless. The highest color level is extremely rare. e grade: colorless. Only gem appraisal experts can detect trace colors. It's a very rare diamond. F level: colorless. A small amount of colors can only be detected by jewelry experts, but it is still considered colorless. It belongs to high -quality diamonds. g -H: close to colorless. When compared with higher color diamonds, there are slight colors. But this color -grade diamonds still have high value. i -J: Close to colorless. Slight colors can be detected. High value. k — M level: The color is darker and the fire color is poor, so the wedding diamond ring network is not provided. It is also recommended that customers not use it. N -Z -Z: The color is dark and the fire color is poor, so the wedding diamond ring network is not provided. It is also recommended that customers not use it.
Three major series of diamond color: Kaipu series: including colorless, light yellow to yellow diamonds; brown series: including brown diamonds of different intensity; Golden, blue, green and other diamonds.
The fluorescence of diamonds
The fluorescence is the phenomenon of visible light under the irradiation of diamonds under the irradiation of ultraviolet light. It is estimated that about 50 % of diamonds will fluorescence. Some people seek diamonds that produce this unique effect, but others avoid buying these diamonds. Different levels of fluorescent effects can only be distinguished by professional jewelry professionals. The level of fluorescence () is divided into four levels: "strong", "middle", "weak", and "no". Generally speaking, the fluorescent level is the middle or strong level, respectively, which can make the surface close to colorless diamonds look whiter at a certain distance to add a sense of hazy or slippery diamond.
In the color of the diamond, compare the appraisal diamond with a set of international standard ratio than color stones. Arrange the yellow Z -level order.
The colors of colorful diamonds are: yellow, green, blue, brown, pink, orange, red, black, purple, etc. The number of colored diamonds is scarce, so the value is also very high.
Pure diamonds are colorless, but because diamonds are formed deep in the earth and are affected by the conditional conditions, diamonds often show different degrees and different colors. According to national standards, according to the depth of yellow or brown tones, it is divided into 11 levels, and the English letters D-N represent different colors. If you judge with personal preferences, diamonds have no best color. Each diamond has its own beauty. However, in terms of quality and value, colorlessness (after cutting is white) is the best color, because this diamond is extremely rare, it is scheduled to be "D" in the "Chinese Diamond Making Standards". But many customers like diamonds with a little color, and even some customers like diamonds with obvious colors. This is the colorful diamonds in their hearts. This type of diamond has won the favor of collectors because of its more rare.
