First of all, it is the cutting of diamonds. The brilliance of diamond is attributed to its unique high refractive index and high dispersion. The master of making dazzling magic is an excellent cutter. It can be seen that cutting is the first factor in choosing diamonds. Gemstone diamonds can release dazzling brilliance through the ingenuity of the cutter. A good incision is like a magic wand. Gently, it gives a diamond magical power. On the other hand, diamonds with proper cutting ratio are also more valuable. When you stare at a diamond, you see the light in the diamond dancing and shining like a rainbow. This is a well-cut diamond.

Secondly, according to the purity of diamonds, almost all natural diamonds have different degrees of inclusions. They are natural traces left in the process of diamond formation, and only natural diamonds have natural inclusions. These natural inclusions record the long and wonderful process of diamond formation. It is an indispensable natural feature of every natural diamond. Diamonds are crystallized from mantle magma deep in the earth, with complex environment, diverse components and extremely high temperature and pressure. After hundreds of millions of years of geological changes, they inevitably contain various impurities or defects. The inclusions in these diamonds will not only affect the beauty and durability of diamonds, but also make them more personalized.

Third, we should pay attention to the color of diamonds. Although natural diamonds can have various colors, most cut diamonds are white. Diamonds have many natural colors, from precious colorless and rare light blue and pink to common light yellow. The more transparent and colorless, the more white light can penetrate and become more colorful after refraction and dispersion. All diamonds of different color grades are beautiful only after careful cutting.

Finally, choose the carat weight of the diamond. The weight of diamonds is measured in carats. 1 carat equals 0.2 grams. 1 carat can be divided into 100 cents, and a 0.5-carat diamond is often called 50 cents. The greater the number of diamonds, the more attractive, dazzling and attractive the effect. Moreover, the preservation and appreciation of diamonds depends on the number of carats of diamonds.
