Have you seen the ring in person?
The GIA report photo shows the sapphire looking less vivid than in the other two photos.
If the other two photos are vendor photos, you don’t know what lighting conditions the ring was photographed in.
By this I mean, what you see with your own eyes in person in lighting where you live (both indoors and outdoors) might not match the colour in the vendors photos. It may look a lot darker in real life in anything less than bright lighting.
And this might matter a lot to you.
In relation to the sapphire, if the vendor photos are accurate it’s a nice vivid blue. It has visible crystal inclusions which might matter, or not, to you.
One point though, are you able to just buy the sapphire alone?
You will be paying a lot extra $$$$ for the sapphire as a sapphire and diamond ring and if you want to use the sapphire in another ring, that’s a bit of a waste of money.
You might be better using the full amount to search for a loose sapphire and get something bigger/ better.
