Before purchasing diamonds, the first thing consumers need to understand is the classification of diamond grades. Diamond grades are not only based on the size of the diamond, but also on factors such as diamond size, color, clarity, and cutting. So, how is diamond grade divided and what is the best grade for diamonds? Let's learn about it together with My Love Diamond Network.

Diamond level

The diamond grade is mainly viewed from the aspects of diamond weight, color, clarity, and cutting quality. To understand the best grade of a diamond, it is first necessary to have a comprehensive understanding of what grades the diamond has.

Firstly, in terms of the clarity level of diamonds, they are mainly divided into five major levels: LC, VVS, VS, SI, and P. These five major levels can be further subdivided into FL, IF, VVS1, VVS2, VS1, VS2, SI1, SI2, P1, P2, and P3. Among these clarity levels, FL-P3 decreases sequentially, so in terms of diamond clarity, FL is the highest clarity level.

Secondly, in terms of the color grading of diamonds, there are several standards for the color grading. D and E colors are extremely white, F and G colors are excellent white, H colors are white, I and J colors are slightly yellow, K and L colors are light yellow white, and M and N colors are light yellow. Among these color levels, the D-N level decreases sequentially, so the D color of diamonds is the highest level in terms of color.

Finally, from the perspective of diamond cutting level, diamond cutting is a often overlooked but very important diamond parameter, and the cutting level artificially determines the degree of diamond radiance. Internationally, diamond cutting is divided into five levels: EXCELLENT, VERY GOOD, GOOD, FAIR, and POOR. Among them, Ideal Cutting (EX) is the highest cutting level.

The weight of a diamond is the unit of measurement for its weight. One carat is equal to 0.2 grams, and the larger the diamond, the rarer it is. Therefore, the larger the diamond, the higher its value. To determine the best grade of a diamond, it is best to consider the grade parameters of the diamond. If the weight of the diamond is ignored, then a D-color, FL clarity, and 3EX cut diamond is the best diamond. However, with these parameters unchanged, the heavier the diamond, the better its quality.

In theory, of course, the higher the diamond grade, the better. However, diamonds with higher grades in all aspects are very rare and expensive, making it difficult for ordinary consumers to afford. If they are worn on a regular basis, it is recommended to purchase diamonds with a score of 0-70, a color grade of I or above, a cleanliness grade of SI2 or above, and a cutting grade of VG or above, without considering appreciation or collection.
