The numbers on that stone are bad. It will have compromised performance.
The entire purpose of faceting a diamond is to reflect light.
How well or how poorly a diamond does this determines how beautiful it is.
How well a diamond performs is determined by the angles and cutting. This is why we say cut is king.
No other factor: not color, not clarity has as much of an impact on the appearance of a diamond as its cut. An ideal H will out white a poorly cut F. And GIA Ex is not enough.
So how to we ensure that we have the right angles and cutting to get the light performance we want?
https://www.pricescope.com/wiki/diamonds/diamond-cut
Well one method is to start with a GIA Ex, and then apply the HCA to it.
https://www.pricescope.com/wiki/diamonds/holloway-cut-advisor
The HCA is a rejection tool. Not a selection tool. It uses 4 data points to make a rudimentary call on how the diamond may perform.
If the diamond passes then you know that you are in the right zone in terms of angles for light performance.
Is that enough? Not really.
So what you need is a way to check actual light performance of your actual stone.
That's what an idealscope image does. https://www.pricescope.com/wiki/diamonds/firescope-idealscope
It shows you how and wear your diamond is reflecting light, how well it is going at it, and where you are losing light return. That is why you won't see us recommending Blue Nile, as they do not provide idealscope images for their diamonds. James Allen and WF do.
The Idealscope is the 'selection tool'. Not the HCA.
So yes, with a GIA stone you need the idealscope images. Or you can buy an idealscope yourself and take it in to the jeweler you are working with to check the stones yourself. Or if you have a good return policy (full refund minimum 7 days) then you can buy the idealscope, buy the stone, and do it at home.
Now if you want to skip all that... stick to AGS0 stones and then all you have to do is pick color and clarity and you know you have a great performing diamond. Because AGS has already done the checking for you. That's why they trade at a premium.

Hi Gypsy: Thanks for your reply.. What numbers on the stone are bad per your comment ? The table or Depth ? Or what part of the proportion do you think is not good. When I checked the Ideal Proportion against this stone it appears to be Ideal. But then again I am a consumer not an expert.
I can afford to pay more.. Do you think I is good or should I wait to find a better color with ex cut ex clarity.. I am conern about the I color. My current diamond is G (VG/VG/VS2) and I am upgrading to a bigger size.

Your originally posted stone is not so good, as Gypsy said. It only scores a 3.5 on the HCA - which is an automatic reject. It will not look good. It will leak light, it won't be as bright and sparkly as an ideal cut stone, and will look smaller and more tinted than an ideal cut stone of the same size. GIA XXX is a very broad category, and some duds get through - like this one.
Gypsy explained everything, and found you a great stone - why aren't you considering it? Plus it's cheaper than the stone you're asking about, and that's without the PS discount!

What city are you located in? Many of the online vendors actually have stores or offices that you can go to - there are some great vendors in NYC and Texas. I have purchased from online vendors but I always visit in person as I need to see them in person.
If you want to stick with your local folks, ask for these specs and then report back here:
Depth: 60% - 62%
Table: 54% - 57%
Crown Angle: 34 - 35
Pavilion Angle: 40.5 - 40.9
Girdle: Avoid extremes such as thin to extremely thick
