The cutting of diamonds refers to the technique used in diamond cutting and processing, and the excellence of the cutting directly affects the diamond's firing and brilliance. Diamond cutting generally depends on three aspects: cutting ratio, polishing, and symmetry, commonly known as 3ex. Each aspect of cutting, polishing, and symmetry is divided into five levels, from high to low: ex (Excellent ideal cutting), vg (Very good), g (Good), f (Fair), and p (Poor).
Diamond cutting
1. EX ratio
Diamonds with standard cutting ratios undergo precise calculations at every angle, resulting in perfect refraction of light entering the diamond and presenting a dazzling and charming fiery effect.
2. EX polishing
Polishing demonstrates the smoothness of the diamond surface. Diamonds with low flatness can affect the direction of light reflection and refraction on the surface of the diamond, thereby affecting the color of the diamond.
3. EX symmetry
Symmetry reflects whether there are any offset or tilt issues in the arrangement of various facets of a diamond. If the symmetry of a diamond is low, it will cause a shift in the reflected and refracted light of the diamond, thereby affecting the fire effect of the diamond.
