General diamond, which is our common prototype cutting, is called brilliant cutting. At the top of this diamond shape, there is a big plane called a table. Then it consists of a crown, a girl, a pavilion and a bottom. Each part has a specific proportion range. These data and values directly affect the reflection and refraction of light by diamonds. Generally, the aspect ratio of diamonds is 53%. If it is more than 53%, the diamond will have a dark effect. If it is less than 53%, the so-called fish scale effect will appear, that is, the refraction of light is too close to the center. Table width ratio is a classification of diamond 4c standard clock cutting.
Table width ratio-the percentage of table width relative to the average diameter. The size of the table is related to the size of the diamond, and it is also the key to whether it leaks light. Americans prefer small countertops, which will make diamonds shine.
The percentage of the average mesa diameter to the average diamond diameter is the mesa width ratio of the diamond, also known as the mesa size of the diamond, which is an important content in the diamond cutting ratio parameters. The standard round diamond table top is a regular octagon, the distance between the opposite tips is the width of the table top, and the average of the four values is the average diameter of the table top. The diameter of the actual round drill is not constant, and the average diameter of the diamond is =(Dmax+Dmin)/2. The larger the table width ratio, the larger the diameter of the diamond table relative to the diamond. The size of the diamond table has a certain influence on the fire and light of the diamond, which is generally 54%-65%.
