When buying a diamond ring, many people will find the same weight diamond ring, but the price difference can be opened very much. This is mainly caused by the different diamond levels, especially for the Dragon diamonds, this difference is more obvious. So how to distinguish the level of diamonds? What are the levels of diamonds?
. Let's first look at the 4C level of the diamond and understand the level of diamonds from those dimensions.
1, weight: The weight unit of the diamond is "carat" or "points", 1 carat = 100 points = 0.2 grams. Diamonds are non -renewable gems. The larger the weight, the more precious. 1 carat is already a relatively large diamond, with a higher value of diamond collection of 1 gram and above.
2, color: For colorless diamonds, the color level of the diamond is intuitively speaking, from colorless to slightly yellow. Diamond color levels are arranged in English from high to low. Among them, the D-level is the highest diamond color grade, which is colorless; E-F is also the same colorless level; G-H is close to colorless grade, and the quality is also high; I-J has a small amount of small amounts; The yellow, but the quality is relatively high in general.
3, clarity: Diamond clarity level refers to the loss of diamonds. Diamond clarity levels are divided into 11 levels of FL, IF, VVS1, VVS2, VVS2, VS1, VS2, SI1, SI2, I1, I2, and i3. FL is the highest diamond clarity level, which has no time inside and outside the mirror. If you want to choose diamonds with diamond ring, you can choose diamonds with SI and above clarity levels.
4, cutting: the cutting level of the diamond is the only level of manual decision in 4C. The quality of the cutting work largely determines the shining of the diamond. Diamond cutting is mainly divided into 5 levels, from high to low, which are (Excel 1), very good work, good cut (good), general cut (fair), and poor Essence

is the introduction of diamond 4C level. When buying diamonds, generally we cannot know the diamond 4C level information accurately through the naked eye. However, there will be certificates for diamond products purchased through regular jewelry stores, and the 4C level of diamonds will be clearly marked on the certificate. Therefore, when choosing a diamond brand, you must choose a reliable brand that provides a diamond certificate. For example, men can customize only one DR proposal diamond ring in their lives is a trusted choice.

The quality of the diamond ring is determined by the diamond. The higher the diamond level, the better the quality. Therefore, the quality of diamond ring is distinguished, mainly depending on diamond 4C, diamond fluorescence, etc. Diamond quality distinction standard: 1, diamond weight
①1ct = 0.2 grams, 1 carat = 100 points. In the case where other parameters are unchanged, the larger the weight of the diamond, the more expensive the price. ② diamonds have a staircase premium, the same quality diamond, 1 carat than 99 points is much more expensive. 2, diamond color
The color from D to Z to 23 levels. D is the whitening, the more yellow, the more yellow, and the H color is the dividing line.
① Perfect collection grade: D, E color ② high quality: F, G color ③ high cost performance: H color ④ budget tightening: i, j color r r ⑤ The yellow visible to the naked eye below the color of the naked eye, directly do not consider 3, diamond clarity

Pay content for time limit to check for freenAnswer Hello, I have seen your question. I am sorting out the answer, please wait a while ~nHello, diamond identification is more complicated: In the 4C standard, the diamond quality is decided to cut, color and clarity. Diamond -cutting quality Diamond cutting quality is very important. It will affect the interaction between diamonds and light, thereby determining the brightness, fire color and flash of diamonds. · Brightness is the white light reflected from diamonds to the eyes of the observer. · Firecai is the color flash that the observer sees when the diamond disperse the white light into a spectral color. · Flash is the flashing and patterns of the bright and dark areas seen when the observer or diamond moves. The above three points are also important factor in the effect of diamonds to show the effect of beautiful light and shadow. Cutting quality refers to the comprehensive impact of diamond proportion, design and modification factors on the aesthetics of diamonds. For diamonds with clear cutting levels, you can further understand the quality of the cutting of the cutting through the following points: 1. Check the brightness and flash of the diamond under the light shot (white light), and observe whether the diamond can reflect a large amount of white light (brightness) ; When rotating diamonds, whether the diamonds are constantly flashing (flash); whether the distribution of light and dark areas is evenly distributed (pattern); if the above conditions are met, it means that its cut quality is better. 2. Check the diamond under the incandescent lamp, and it should be as much as possible with various colors of fire. 3. Observe diamonds under various light conditions. From the source of light to the point of light, different light environments will greatly change the appearance of the diamond. If the diamond looks very good under different light sources, then this may be a very good diamond. The color quality of the diamond GIA creates the D to Z color grading system to divide the color level of colorless diamonds. Generally speaking, the less the diamond color, the more popular people are. Among them, only diamonds with color level D are completely colorless, and diamonds at level Z look obvious yellow. The quality of the diamond is good or bad, and the results of the level division of authoritative institutions can be referred to. Diamond's clarity quality is divided into "flawless"-"inner level" in the GIA diamond clarity grading system. But even the "flawless" diamond may not be flawless. "Flawless" only means that after 10 times the diamonds are enlarged, they cannot see the inner content or surface characteristics. When choosing a diamond, people have different requirements for clarity levels. Some people with perfection may be difficult to accept defective diamonds, but some think that flaws are unique marks of every natural diamond. It affects the aesthetic effect of diamonds. Combined with the Diamond GIA level division and consumer purchase guide, determine the quality of the diamond clarity: 1. The internal content can be seen without the naked eye. If you do not zoom in observation, you cannot see any internal contents, or you can only see a small number of internal contents that are difficult to find. 2. The position, size, and obvious degree of the inner contents can be seen. If the inside is hidden near the edge of the diamond, near the sharp angle, or diagonal angle, it will not look so obvious. In particular, the internal content near the edge of the diamond may even be blocked by claws after inlaid as the finished product. If it is smaller, facenIt is more difficult to discover in the lighter color, and the impact on the appearance of the diamond is even less. 3. Cutting sample. The round bright -cut diamond is more aspect, and it is usually not easy to find the inner content. The more face -to -face, the easier the light is reflected to everywhere, forming a complex pattern, so that the smaller inner content can be hidden. The staircase -cut diamonds are larger (such as emerald -shaped diamonds), and the number of aspect is small. The patterns generated are not complicated, so it is easier to notice the inner content.n1 morenBleak
Seeing the 4C level of this diamond, 4C determines the quality of the diamond. The consideration (4C): 1, color: the best colorless, the deeper the color, the worse the quality. In the color grading of colorless diamonds, the top color is D color, and it is arranged to Z in turn. D-F is a colorless level, G-J is a near-color level, and K-M is slightly yellow. 2, weight: the greater the weight, the higher the value.钻石的重量是以克拉为单位的，1克拉（ct）=0.2克（g）=100分rn3、净度：净度分级的依据是内含物的位置，净度级别由高到Low can be divided into FL (perfect flaw), IF (flawless), VVS1-VVS2 (extremely light flaw), VS1-VS2 (mild flaw level), SI1-SI2 (micro flaw), P1-P3 (flawless flaw Level) 4, cutting: from high to low, divided into EX (perfect), VG (good), G (good), F (general), P (low) n level level The higher the higher.
It simple identification methods of diamonds: need to use a 10-20 times large mirror to assist and make several simple observations. Method 1: Observe the waist of the diamond. If it is sandal waist circumference, it is most suitable for this method. Because diamonds are harder than any imitation products, they will not appear thin stripes like imitations. It is a granular appearance. Method two: Diamonds are harder than imitation, and the face lines of imitation are often more dull than the diamond feeling, and the diamond's face line must be sharp. Method three: Based on diamonds, it is harder to rigid imitation, and the face lines of imitation are often wear. Method 4: If the diamond leaves a natural face, there is a chance to discover the unique "triangular growth pattern" of diamonds on the natural surface. Method 5: If the diamond appears, the appearance is usually staircase, and the imitation of imitation will be bent or shell -like.
