Hi there, I'm debating between the two stones above.
They both fit my budget for under 3K for the diamond, I'm leaning towards the J color stone as I'm afraid the K will look a faint yellow under certain angles. But on the other hand I do like the fact the K is ACA diamond.

When looking at the idealscope images I can't really see much of a difference in cut, was the J just short of making the ACA grade?

Thanks in advance for your opinions.

I like the J. It has a tiny table and a higher crown. Plus it's a J. As long as it is eyeclean that is my choice.

 

[Dancing Fire]

Yup, go for the J.

 

[teobdl]

Go with the J.

J.

Wouldn't go below J for an e-ring. The J stone is a very nice ideal cut diamond!
