Hi TEA, welcome to the forum.

You can ask your vendor to run the diamond on Sarin or OGI machine.

What are other numbers, proportions, measurements for the diamond?

Thanks for the reply.

Here are the numbers:

Measurements 5.7-5.72-3.5 mm
Depth Percentage 61.3 %
Table Percentage 55 %
Girdle THN-MED F
Culet NO
Polish Excellent
Symmetry Excellent
Fluorescence None

What should look for the crown Angle and Pavilion Angle numbers?? As you can tell, I am new.

3.5 means the total depth in milimeters.

The diameter of the stone is about 5.71 mm. Hence the total depth % = 3.5 / 5.71 = 61.3%.

TEA as Leonid noted, the only way to get the crown and pav angles is to have the stone run through a Sarin/OGI machine. Ask your jeweler to do this for you or to find someone who will. The resulting report will have the angles for you to use. Also specify you want the angles and not percentages as angles are more accurate.

Then people can give you more educated info on the stone. Good luck!
