The diamond certificate contains information on its main parameters, such as:

  • fluorescence

In addition, some measurements of a diamond are to be done, which are:

  • minimum diameter;

  • length and width (for fancy shaped diamonds);
  • total height;
  • table size;
  • crown angle and pavilion depth;
  • girdle thickness;
