What is the perfect proportion of diamond table top? The quality of diamond cutting is an important criterion that affects diamond fire color, but in fact, the shining degree of diamond fire color has a great relationship with the proportion of diamond cutting. Diamond cutting ratio is divided into many parts, such as crown height ratio, table top ratio, pavilion depth ratio and so on. Tip ratio, etc. Today, let's take a look at the range in which the diamond table ratio is the most perfect.

The diamond proportion is the most important factor to determine the quality of diamond cutting, which refers to the percentage of other parts relative to the average waist diameter 100%. If the ratio is just right, the diamond will shine, and if the ratio is not good, the diamond will be eclipsed.

What is the diamond watch ratio? Diamond table is also called "diamond table width ratio", which is recorded as a table on GIA certificate. The ratio of the maximum width of circular diamond table top to the average diameter of diamond waist and the ratio of table top width to diamond width are used in colored diamond, and the result is the percentage of diamond table top. The percentage at the top of the table is an integer result, rounded to the nearest decimal point.

Influence of diamond plate proportion

Diamonds with larger tables are more malleable and usually look brighter. They reflect more light to the observer's eyes, but usually these diamonds have a worse fire color than diamonds with smaller countertops. To sum up:

The size of the table directly affects the brightness and fire color of the diamond. If the table is too big and the brightness is too high, the fire color will decrease. The mesa is too small and the brightness is too small, but the fire color will increase.

For diamonds below 0. 1 carat, large diamonds are usually more popular than small diamonds.

What is the perfect proportion of diamond table top?

What is the perfect proportion of diamond table top? There are also many different views on the standard of mesa size, and there is no unified standard so far. When the crown angle is ideal 34.5, the common mesa ratio is 58% to 65%. Too small or too large a table will affect the fire color of the diamond itself to a certain extent, which is not what most people like. Different people have different preferences.

According to the suggestion of the Gemological Institute of the United States on the classification of diamond cutting and grinding, the ratio of the standard round diamond table is between 53 and 62, which is an ideal cutting.
