AGS0 from James Allen or a GIA EX/EX from a local B&M

[777php]

I went ring shopping on Friday at the Gifcenter/Jewelrymart, where I saw a diamond that I liked. I was given a quote and shown the GIA cert with an EX/EX on polish and symmerty.

However, I don''t have the crown and pav angles so I cannot run it through the cut advisor to determinte wheter or not it is a AGS0 or not. I know that the tool is not final and subject to change but I like that I can use it to provides some feedback

I''ve also been keeping my eye on a diamond from James Allen, with the exact same specs as the stone at the brick and mortar store, with the exception that it is 0.3ct smaller and I know all the angles and depths. Running it through the advisor it returns a 0.6 - Excellent rating, or an AGS0.

My question, knowing the above about the two stones is buying from James Allen a safer play since I know that the cut I am getting is a great one?

How heavily should I weight the AGS0 rating when comparing the two stones? In the future in terms of appreciation or value maintainence will an AGS0 provide me with a greater benefit?

Thanks!

Well you don''t have as much information on the local stone to know exactly what you are getting for the money, but you do have the advantage of having seen the diamond with your own eyes. How did it look to you??? As far as the James Allen stone goes the crown angle is less than would be my preference.
