  • This application relates to the field of jewellery, and in particular to an octagonal diamond.

  • the diamond identification 4C standard is the international standard for weighing (carat), color, clarity (transparency), and cutting standards to measure the quality of diamonds.
  • Princess Square Cut is one of the fancy cut diamonds. It has a square appearance. The advantage is that it makes fuller use of the diamond blank, making the diamond look 10% to 15% larger than the round diamond. Due to the unique cutting, the proportion of the table top of the square drill is larger than that of the round diamond under the same score. However, it is precisely because the princess diamond is a square with four sides and equilateral angles. Therefore, in order to obtain a completely symmetrical princess-shaped diamond, the utilization rate of the rough is not complete enough, and some raw materials will be lost. Moreover, because of the square shape of the diamond, the corners are easily broken during the setting, which greatly reduces the value of the jewelry.
