AGS round brilliant guidelines

[HansenDeHCA]

I was looking at the "ags guidelines", what do the following 2 indicator mean? thanks

1) xx Table (e.g. 47 table)



2) xx MM

47% table which is (width of table/diameter of stone)x100 = table%
12mm is the diamond diameter.
In the examples you posted.

should I round up or round down the diamond diameter?
e.g. 7.19-7.26mm x 4.39mm
guess I will refer to 7mm table?

If two numbers for diameter are listed the largest one was used for calculating table % for a rb.
Rectangular stones use the smallest width and the matching table width to calculate table %.
