In order to make a reasonable judgment on classification and fully understand the value and price of diamonds, we must consider making an objective judgment from a professional point of view, so that the actual classification standard becomes the key to accurately judge the classification characteristics. As a general industry standard, diamond 4c classification will be combined with this industry standard in the actual business process of diamond jewelers, so that consumers can determine the value and price of their purchased products on the basis of professional classification.

It is necessary to classify diamond products objectively.

Professional requirements and specific strict standards should be considered as the basis. When ordinary consumers choose high-quality diamond products, they should also pay special attention to their grades and determine their prices and values. The grading of diamond 4c is a universal standard, and four aspects should be considered comprehensively. The purer and more natural high-quality diamond, the bigger the particle, the heavier the weight, the higher the grade and the higher the value. Diamond color, diamond clarity, diamond cutting and diamond carat are four aspects of 4c standard, and comprehensive judgment and consideration are the key to evaluate the grade.

Color grading

In the color classification of diamond products, the lighter the color, the higher the value, so the better the colorless diamond. But in specific products, it is often difficult to distinguish the color of diamonds with the naked eye. Generally, it is necessary to classify them with the help of instruments, determine their color shades and compare them. Judging the grade of a diamond according to its purity, the purer the flawless product, the higher the grade. According to the number, location and size of defects, the classification of grades is often determined by comparison to a great extent, and the fewer defects, the better.

The grade of diamonds is influenced by many factors.

In the process of manual cutting, maintaining its perfect shape and chromaticity is an important criterion for judging the grade. Diamond cutting mainly depends on the ratio of facet cutting and grinding and the quality of technology, as well as the brightness and flicker of the final diamond and the effect of fire color. This is mainly divided into excellent and excellent grades. Of course, the most direct diamond grade is weight, which is the so-called carat number of diamonds. This standard is very simple, the bigger the heavier the better, which is also the most direct standard for comparing prices in the general market.
