The color of the diamond ring can be divided into four color series: colorless to light yellow series, tea -to brown series, gray series and color series. The vast majority of jewelry are colorless to light yellow collar series with diamonds. Only this series of diamonds have established a clear color level, grading rules and corresponding standard stones. The national standards of Chinese jewelry and jade divided colorless transparency to light yellow (including brown and gray) diamonds, divided into twelve levels.
D level: completely colorless. Diamond color is the highest level, perfect colorless, and relatively the highest degree.
e grade: colorless. The only color of the diamonds can only be tested by gem appraisal experts, which is relatively rare.
F level: colorless. A small amount of colors can only be detected by jewelry appraisal experts, and they are still considered colorless and high -quality diamonds.
g ~ H level: close to colorless. Compared with higher color diamonds, it has a slight yellow color and still has high value.
i ~ J -level: close to colorless. Slight colors can be detected. High value.
k ~ M level: The color is visible to the naked eye, the color is dark, the diamond is dim, and rarely provides this color diamond. The color level is low and the visual effect is poor. It is not recommended to buy customers.
Extended information:
In the color level of the diamond color, the common white diamonds are mainly the naked eye. In the case of cost-effective selection standards, it is usually recommended to choose the I-J color. And those who are pursuing perfection can choose D -color diamonds; when buying colorful diamonds, the pursuit of color is mainly strong, but if there are not many budgets, you can choose Fancy Light from the aspect of cost -effectiveness. Level.
If to test the color of the diamond between the two consecutive color stones in the adjacent, the color level of the diamonds to be tested is based on the lower color level. Minor difference.

Hello, everyone, I am cotton, and I will share different wonderful information every day.
It today we will discuss that the color of the diamond ring can determine its level. Do you know these common sense?
Let's talk about it.

Is when selecting the color level of the diamond, the common white diamonds do not see the colors of the naked eye. Under the circumstances of the price / performance ratio, it is usually recommended to choose the I-J color and pursue the pursuit of pursuing Perfect people can choose D -color diamonds; when buying colorful diamonds, the pursuit of color is mainly strong, but if there are not many budgets, you can choose Fancy Light (light color) level from the aspect of cost -effectiveness.

The colorlessness in the diamond 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.

The diamond clarity level is also very important
The clarity of diamonds usually uses 10 times large mirror on the inside of the diamond, surface flaws and its degree of influence on glory to the clarity level of unsolved diamonds inlaid diamonds The grades, according to the standards of Chinese national inspection, are subdivided into 10 levels of LC, VVS1, VVS2, VS1, VS2, SI1, SI2, P1, P2, P3. The inlaid diamonds are divided into excellent, good, good, better, generally 5 levels. P -level diamonds are also called Class I diamonds. The following P -level diamonds are generally not used as gems, so they are generally only divided into P levels and no longer divide.
The international interpretation of IF, VVS, VS, Si, and P is commonly used as:
(1) IF is perfect flawless. To defects -everyone remembers: domestic inlaid diamond grading is impossible to give this level.
(2) VVS subdivisions are vvs1, vvs2. V = very, VVS -is very, very (very very) and small internal content -professional diamond grades are also very difficult to find Point tip -like internal content.
(3) VS subdivisions are vs1, vs2, VS levels are larger than VVS, and it is difficult for professional diamond grades to find that VS2 levels are more than VS1. VS level is the dividing line of high -quality diamonds.
(4) Si is subdivided as SI1 and SI2, which are small flaws. It is easy to see defects SI1 under ten times the magnifying glass. Essence Therefore, the naked eye above SI when purchasing diamonds cannot distinguish the difference.
In the diamond trading market, the color of diamonds is divided into seven levels of D, E -level, F -class, G -Class, H -class, I, J -Class, K, M, N, and Z levels.
The diamond D color is high -level, which is completely colorless and very rare.
DEF (transparent colorless) level is relatively rare and generally high.
ghijkl (close to colorlessness) is relatively more level, like diamond rings, all I-J colors.
mn (pale yellow). This level of pale yellow is already visible to the naked eye, and the price will be much lower; after
n, Y is also yellow, and the price will tend to cheap.
But the last Z (color diamond) level is more rare and more expensive than the first level D.
? Generally, three levels EX (perfect) VG (very good) g (good) g (good) g (good) g (good). We often hear 3EX cutting when buying diamond ring. In fact In addition to the most important cutting work, it also includes polishing and symmetry. The quality of cutting is mainly reflected in the fire of the fire. Now the "eight hearts and eight arrows" that everyone admire may not be a good cut.
Diamond colors are divided into D, E -level, F -class, G, G -grade; H -level, level I; J -level, K -level; M, N -level seven levels. Diamond D color is high -level, which is completely colorless and very rare. Diamond J color refers to the slightly yellow view from the pavilion, which can detect slight colors. Observation from the table is close to colorless. This level is close to colorless, value value, value Higher. The higher the color level, the more expensive the price of diamonds, but it is difficult to judge the diamond D and J colors from the naked eye. Generally, H color is the dividing line of high-quality diamonds, that is, the Holin or above is basically not slightly yellow. From the price factors, the color of the diamond color is recommended to choose H color and I-J color. High, but for large diamonds, such as more than one carat, the color will be slightly more obvious. Diamond D colors are a good level, and the quality of diamonds is also high. Diamond J colors are suitable for people with ordinary people to buy. The price is moderate, and the color is not easy to see the color. K -level; M -level, N -level; level Z's color visible to the naked eye, poor fire color, diamonds are dull, and the visual effects are poor. Therefore, it is not recommended to buy it.
