I'm very picky, but that indented natural would not prevent me from buying the diamond if everything else was groovy.
But it's not groovy.
It's too deep for me.
The light performance is not as good as it could be.
Too much light will leak out the sides and bottom instead of being directed to reflect back out the top to your eyes.
Others here would be glad to dive into what specific combinations of which specific measurements and angles would have better light performance.
Unfortunately, while GIA is one of the most reputable gem labs, their cut graded of Excellent is not as excellent as it should be. This makes higher profits for vendors and GIA. Very dissapointing.
I'd keep shopping.
Also there's another vendor with better policies than Blue nile, Whitflash.
Also WF sells a line of diamonds called ACA, A Cut Above, that all have the ideal combination of parameters that deliver top light performance.
I like the ease of having only to decide on weight, clarity, and color for my budget.
It is much smarter to find a round with an HCA under 2 than focus a rule onto one single parameter, because the multiple parameters interact.
So, one number may be good or bad, depending on the other parameters.
The HCA does the math for the combination of parameters you enter.
That's what makes the HCA a brilliant invention.
Still, 62.7% is quite deep.
Besides light performance concerns, a deep diamond is said to be "hiding" carat weight in its depth.
That means it will face up small for its weight, compared to a round that's not so deep.
A very shallow round will face up large for its weight, but when too shallow it will also suffer from poor light performance.
I don't love the leakage/obstruction I see at 6 o clock. But it's certainly not a bad stone. Options I prefer at BN that are the same price or less than the one you have on hold:
