Help me choose between diamonds for engagement ring

[dkidsun]

Just to get it out of the way - I am very new at this and am feeling slightly overwhelmed. Looking to procure an engagement ring and am comparing diamonds on whiteflash and brian gavin. I live in Canada but near the border.

The setting will be pretty traditional - am thinking a tiffany knife edge.

The general specs that I've narrowed down are below.

1.25-1.5carat
Best cut possible
I+ colour
VS+ clarity
Budget is <15k

Here are some diamonds that seem to meet my criteria. Any thoughts or any others I should consider? Should I tighten my color criteria a bit to H or G+ given my budget?

Thanks in advance for your help.

Just with the little bit of info you have given us, I would
Probably go with the H. I would like to see the
Idealscope for it first though. I'm sure it's fine but
Just to be sure.

Edit ...make sure its eye clean also.

If you really have up to $15k, then the G VS2 ACA would be the easy choice. I prefer VS2+, so my second choice would be the 1.44 I VS2 ACA.

I think all of the WF stones would be ranked over the BG stones since they are smaller. It isn't always easy to access stones in the 1.4 range, and WF has some excellent choices at the moment!
