The selection of loose diamonds is mainly aimed at 4C, as well as "carat, cut, carat degree and color".
Briefly introduce 4C department:
Color: White diamonds are mentioned here. From completely colorless to yellowish brown, completely colorless diamonds are also the most perfect white diamonds, which are very rare. The average customer has more choices, and it is enough to look white with the naked eye. There will be more in the F-G file. Please refer to the following figure for specific visual effects.
Cutting: This is the key to the quality of diamonds, which refers to the position where diamonds are cut and processed. Excellent cutting can make the diamond fully refract all light and give off beautiful fire color without leaking light. Therefore, in order to ensure the shining degree of diamonds, it is best to choose diamonds with good cutting, polishing and symmetry, referred to as 3EX.
Kral: It refers to the content of diamonds. The less inclusions, the better. Generally, under the magnifying glass of 10 times, if the purity of impurities is not visible to the naked eye, it can be purchased. The invisible defect level with high cost performance is VS, and inclusions may be seen at a lower level, so VS level is generally recommended. Please refer to the figure below for details.
Carat: It's the weight of a diamond, that is, its size. It all depends on your budget.
The diamonds of Chow Tai Fook and Lao Fengxiang should have a brand premium. For example, diamonds customized by general custom brands cost around 10,000 yuan, which may be slightly higher.
The style should be considered according to the hand type of the wearer. Personally, I prefer some styles with a sense of design, especially small.
