What does the diamond 4C standard mean? The so -called 4C standard refers to the four aspects: Carat Weight, color (color), and clarity. They all start with the letter "C", so referred to as "4C". This diamond 4C standard is the GIA American Gem Institute for the Diamond Diamond Diamond Diamond Division of %%. 1. Diamond weight cact: carat is the weight unit of diamonds. 1 carat (1 ct) is equal to 0.20 grams and is divided into 100 points. The weight is the main factor that determines the price of diamonds.

2. Diamond color color: Diamonds have a variety of natural colors, from precious colorless (white after cutting white), rare light blue and pink to common slightly yellow yellow. Essence The more transparent, the more white the white can penetrate, and it is even more colorful after refraction and color. White diamonds are set to D %% (that is, start with Diamond's letters). The color of the diamond is divided into 11 %%. From D to Z, it is arranged in order of alphabets.
3. Diamond clarity Clarity: The clarity of the diamond is based on the number, size, and position of the inner content. Press FL (internal flawless = no visible inner content under the observation of 10 times the large mirror) to i3 (no, diamond with the inner content of the naked eye).
4. Cuts of diamonds: refers to the accuracy of the cutting ratio of the cutting rate and the sexuality of the decoration. Good cuts should be as high as possible, and the brightness and fire color of diamonds should be reflected as much as possible, and the weight of the rough is as much as possible. GIA's cutting is divided into Excellent (
Diamond 4C is the standard for assessing diamond grades, including carat weight (), clarity, color (color), and cut grinding (cut). Since the letter starts from the letter "C", it is referred to as 4C.
1, carat weight
carats are the indicator of the most understanding of diamond consumers, because the larger the diamonds of many people, the more expensive the diamond is. This is not too Big mistakes, but once there are comparison, this standard is not so accurate, because one carat diamond may appear more expensive than two carats, which involves other diamond judgment indicators.
2, the clarity of the diamond
in the process of formation, not only carbon elements, there must be some other "impurities" elements to participate, these "impurities impurities impurities "It will cause the diamond to be not so pure and transparent, and the diamond will not be so" flash ".
3, the color of the diamond
The color of the diamond, the higher the value. Most diamonds on the market are transparent diamonds, and high -quality diamonds are pure monochrome.
4, cutting
This is the only man -controlled factor. Make diamonds more "flash". A good diamond jewelry is particularly important.
Internationally use weight (carat), color, Mingcheng (transparency), and cutting standards to measure the advantages and disadvantages of diamonds. For short 4C, the first English letters of the four measured projects of Carat, COLOR, Clarity, and Cut. . In the case of color, transparency, and cutting, the larger the single particles, the more valuable diamonds. The weight of the diamond is calculated in carats, 1 carat = 0.2 grams, 1 carat = 100 points. The color grade (color grade) grade can be divided into general 5 levels from D -Z. Among them, D, E, and F are colorless (COLORLESS), with D as the optimal, E and F as the second. Later is G, H, i, J as the near colorless (Near Colorless) close to colorless. The then -level from K -Z is colored. K, L, M (Fain Yellow) are slightly yellow, and N -Z is the most bad (Very Light Yellow, Light Yellow) slightly yellow. transparentness This orange degree and transparency can be divided into general 5 levels from F -I. F. IF is the optimal level, nearly transparent, very precious and rare. VVS1 and VVS2 are high -level products. Later, Si1 and SI2. Then it is i1, i2, i3. The cutting Cut finish can be divided into 6 levels, which are Excel all, very good, good, medium, fair, poor.
The diamond ring 4C standard is formulated by the GIA American Gem Institute. It is now internationally commonly used to measure the quality of diamond quality. 4C includes four aspects: diamond cut, color, clarity, and weight. When buying diamonds at any time, we must comprehensively consider these four aspects. If it is a proposal diamond ring, in addition to the quality of quality, you must also choose a brand with a romantic meaning.
