Been lurking around the forums for a bit now and stumbled upon the HCA tool.
I recently found a stone that met all my criteria, price included.
It is a GIA certified Excellent cut, Excellent symmetry and VG polish, thin to med faceted.
I was set on purchasing this stone, and this morning saw the HCA tool, decided to input the following proportions:
Depth: 62.3%
Table: 55%
crown angle: 35
Pav angle: 41.4
Cutlet: 0
To my shock, the results showed up as a 4.8!!! VG, fair, fair, VG
In comparison, the following measurements (another stone I saw but is a bit more expensive) got a HCA grade of 1: To me the differences in angles proportions seemed to minute:
depth: 62.7%
Table: 55%
Crownangle: 35
Pav angle: 40.6
cutlet: 0
Is there really this much of a difference between 2 GIA excellent cut stones?
Any guidance here would be greatly appreciated. Right now I don't know what to do.
thanks!
