Garry, why is the 3.50ct still graded as EX sym - shouldn't it have been graded as only vg or gd? I know GIA are have a very broad range within each grade but is this too broad.
Is this an argument to stick with AGS stones because you know what you are getting.
Also, as a matter of interest what is your cut-off in terms of color and clarity in a stone of this size.
Thanks
GIA symmetry grade Ex should indicate that the facets join up well. (i.e. meet up at well defined points) You can have an AGS Ideal / GIA Ex on symmetry and still have low optical symmetry - they are different symmetries.
Thanks for the info Garry
