the price of diamonds is mainly determined according to the 4C standard of diamonds. Combined with 4C pricing, the reference price of 1 carat ranges from tens of thousands to hundreds of thousands the 4C standard of diamond can be divided into: weight, cleanliness, color grade and cutting level , the higher the 4C standard of diamond, the better the quality of diamond, of course, the higher the price 1. Diamond color classification diamonds are first divided into color diamonds and white diamonds, among which the more precious and rare ones are red, pink, blue, green and other colors. The most common are white and yellow diamonds. The purer the color, the higher the transparency and the higher the price. Under the magnifying glass, diamonds come in many colors taking white diamonds as an example, 100 point color diamonds are rated D, 99 point color e, etc. Up to grade J white diamonds are still called naked white diamonds, while Grade K and below white diamonds are called non white diamonds (because the naked eye can see their color turn yellow). Among them, D ≤ f is colorless, G ≤ J is nearly colorless, the latter is of little collection significance 2. Diamond cleanliness refers to the content of diamond, which is a natural sign of diamond itself. If there are less impurities in the diamond, the less conspicuous the position is, the higher the grade of the diamond will be, and vice versa. The cleanliness grades are FL, if, vvs1, VVS2, VS1, VS2, SI1, SI2, Si3, P / I1, P / I2, P / I3 3. The weight grade of a diamond is 0.2g, 100 points. Generally speaking, 1 carat is a dividing line, and the diamonds below 1 carat are much lower than 1 carat. Under other conditions, the greater the weight of the diamond, the higher the value of the diamond 4. Cutting level diamond cutting is mainly e to the symmetry and balance of diamonds, which is also the only human factor affecting the value of diamonds. The reason why diamonds flash is mainly because of the diamond after cutting, which is the problem of diamond cutting. How to grade diamonds is also very important in cutting. High cutting grade, beautiful diamond, high price. The cutting grades are ex, VG, G and P extended materials: the reference significance and application of diamond price related standards: 1, "4C" is your standard to judge the value and quality of a diamond. It refers to carat weight, clarity, color and cut of diamond. You can understand the value and quality of a diamond by comprehending the four points of 4C. Diamond price = weight + Color + clarity + cutting 2. Therefore, the more popular concept is high-quality brilliant diamond. The three principles of 4C: clarity, color and cut are generally grasped for high-quality and brilliant diamonds, and the three standards should reach certain standards at the same time< br />

different grades of diamonds have different prices. 95% of my friends don't know how to calculate the price of diamonds. I'll teach you a method: there are diameters and heights on the diamond appraisal certificate. For example, in the appraisal certificate, you can see that the clarity of your diamond is VS1, the color is h, the weight is 1 carat, and the diameter is 6.22-6.25 mm. Your calculation formula is:
the third power of the diameter multiplied by 0.00366, Example:
6.22 x 6.22 x 0.22 x 0.00366 = 0.8807, that is to say, your 1 carat diamond is actually the diameter of 0.88 carat diamond, which is weight preserved and hard processed into 1 carat diamond! If you buy a 1 carat diamond, you will lose a lot. The error of the calculation results is better between 0.03-0.04 mm, which is one of the best diamond cutters.

more formal jewelry stores, The retail price of diamonds is generally composed as follows:
the cost price of diamonds is x17% (VAT) X5% (high consumption tax) x10-30% (counter rent) x3-5% (promotion fee) X3% (advertising fee) x30-40% (profit)
for example, the retail price of one carat VS1 + H + GIA naked diamonds is one Generally:
according to the cutting grade, it is 95000 yuan-75800 yuan / carat
however, e to different counter rents and different purchase channels, the price gap in retail malls is very large
the diamond with perfect cutting, eight heart and eight arrow cutting, and very standard diameter and height only account for about 15% of all diamonds. Therefore, the price of a diamond with perfect cutting should be increased by 15%
3. Why is a diamond with perfect cutting so expensive
example: 1 carat bare diamond needs 4-5 carats of rough diamond to cut perfectly
for the same 1 carat bare diamond, the cutting generally only needs about 2 carats of rough diamond<
you now understand that the purchase cost of 2-carat and 4-5-carat rough diamonds is the geometric base,
diamonds are sold very cheaply, even surprisingly cheap, and 100% of them are greasy. If the price
of a diamond with perfect cutting is very cheap, why sell it to you at a price lower than the purchase price
so far, my friends and I, as well as friends from foreign diamond dealers, have no problem not seeing a "very cheap" diamond. Of course, stolen and robbed are not included in this case.
95% of friends don't know how to calculate the price of a diamond. They teach you a method: the diamond appraisal certificate has a diameter and height. For example, in the appraisal certificate, you can see that the clarity of your diamond is VS1, the color is h, the weight is 1 gram, and the diameter is 6.22-6.25 mm, Your formula is: the third power of the diameter multiplied by the coefficient of 0.00366, for example: 6.22 x 6.22 x 6.22 x 0.00366 = 0.8807, that is to say, your 1 carat diamond is actually the diameter of 0.88 carat diamond, which is weight preserved and hard processed into 1 carat diamond! If you buy a 1 carat diamond, you will lose a lot. The error of the calculation results should be between 0.03-0.04 mm, which is one of the best diamond cutters. Compared with regular jewelry stores, the retail price of diamonds is generally composed of: cost price of diamonds x 17% (value added tax) x 5% (high consumption tax) x 10-30% (counter rent) x 3-5% (promotion fee) x 3% (advertising fee) x 30-40% (profit). For example, the retail price of one carat VS1 + H + GIA naked diamonds is generally: according to the cutting grade, However, e to different counter rents and different purchase channels, the price gap in retail malls is very large. The diamond with eight hearts and eight arrows is truly cut perfectly. The diamond with very standard diameter and height only accounts for about 15% of all diamonds. Therefore, the diamond with perfect cutting needs to add 15% of the price. 3. Why are perfectly cut diamonds so expensive? Example: 1 carat bare diamond, cutting perfect need 4-5 carat diamond blank to complete; The same 1 carat bare drill, cutting generally only need about 2 carats of diamond rough can be completed. You now understand: 2 carat rough diamond and 4-5 carat rough diamond, the purchase cost is geometric base, diamonds are sold very cheap, or even surprisingly cheap, 100% is greasy. If the price of a diamond with perfect cutting is very low and it is bought everywhere, why should it be sold to you at a price lower than the purchase price? So far, my friends and I, as well as friends of foreign diamond dealers, have not seen a "very cheap" diamond. There is no problem. Of course, stolen and robbed are not included in this case.

Quoc GIA is a Chinese Vietnamese word corresponding to the word "Guo" and "Jia" in Chinese characters respectively
NHA nuoc is a pure Yue word, which has no direct correspondence with Chinese characters. NHA means "home", not "home". In fact, Nha has a character Nan corresponding to "Gou", "dian" and "Wei". Nuoc means water, which also has a character Nan corresponding to "Shui", "Guo", "Chu", "Zhao" and "Wei" "Xi" and several other Chinese characters correspond to each other, and the combination of the two characters means country. In short, in the analysis of Chunyue words, we can not simply understand that one of its characters is corresponding to Chinese characters, and its source will be much more complex
there are many Chinese Vietnamese words and pure Vietnamese words in Vietnamese. In addition to the above example, there are also examples, such as: "method" Chinese Vietnamese word is Phuong phap, pure Yue word is cach“ The Chinese and Vietnamese words of "Hope" are hy Vong and the pure Yue words are Meng muon“ AI tinh and tinh yeu are the Chinese and Vietnamese words of "love"“ There are many Chinese and Vietnamese words, such as tap Quan, Thoi Quan and so on
this is e to the influence of Chinese culture on Vietnam for thousands of years, just as many Chinese loanwords are still used in Japanese and Korean nowadays
as for the usage of hanyue and Chunyue, the basis is different. A large part of Chinese and Vietnamese words are still used in daily life. Generally speaking, the more Chinese words appear in formal occasions or written texts, the more pure words appear in spoken language, and the higher the cultural level, the higher the frequency of using Chinese and Vietnamese words; Some Chinese Vietnamese words are rarely used, and most Vietnamese don't understand the meaning of these words. Moreover, the meaning of many Chinese Vietnamese words in Vietnamese is different from that in modern Chinese. For example, the Chinese Vietnamese word Dong tinh corresponds to "sympathy" in modern Chinese, but Dong tinh means "approval" rather than "sympathy" in Vietnamese. In addition, there are other differences, which are one of the difficulties of Vietnamese
in addition, related to your question, it is also worth mentioning that although many Chinese and Vietnamese words are still widely used, most Vietnamese only know the combined meaning of these Chinese and Vietnamese words, but can't explain the meaning of the words one by one. For example, "hope" Chinese and Vietnamese words are hy Vong and pure Yue words are Meng muon; When using pure Vietnamese words, Vietnamese people know that Meng muon is hope, and they know the meaning of Meng and muon respectively. When using Chinese Vietnamese words, Vietnamese people only know that hy Vong is hope, but they don't know what hy and Vong mean respectively (a few people with high cultural level or Chinese Ecation background may know). In Vietnamese linguistics, Nha nuoc is a compound word, while Quoc GIA is a single word
as for the National Bank of Vietnam, it is generally said to be Ngan hang NHA nuoc Viet Nam
there are four factors that affect the value of diamonds, which are commonly known as 4C criteria. They are color grade, clarity grade, carat and cut proction finish
the level of color is: it can be divided into five levels from D to Z. Among them, D, e and F are colorless, D is the best, e and F are the second. Next, G, h, I and j are near colorless. After that, k-z is colored, K, l, m (fant yellow) is slightly yellow, N-Z is the worst (very light yellow, light yellow) is slightly yellow
cut proction finish can be divided into six grades, namely, excellent, very good, good, medium, fair and poor
cleanliness grade: it can be divided into five grades from F to I. F. If is the best level, almost transparent, very precious and rare. Vvs1 and VVS2 are high grade procts. Then SI1 and SI2. And then I1, I2, I3
carat: in the case of excellent color, transparency and cutting, the larger the single particle is, the heavier the diamond is. The weight of diamond is calculated by carat, 1 carat = 0.2g, 1 carat = 100 minutes
there are professional grading organizations, such as University of Geosciences and GIA School of gems
so, if you just give one carat, the weight may be several hundred thousand. It may be millions or tens of millions of customers.
