Opinions on these three diamonds

[TT0647]

Hello everyone! I am considering to buy a loose diamond and I have narrowed my seletions down to the following three.

The first one got a HCA score of 1.1 and the second one only get 2.6. But if you look at the photos on the GCAL reports, the second one dose look brighter than the first one. And the Optical Symmetry Analysis photos beteen these two are so different as well. I am so confused and if somebody can help that will be great.

My favourite is the third one and it dose cost more , but please advise if the quality of this one is much better than the other two.

How about this one? http://www.bluenile.com/round-diamond-1-carat-or-less-signature-ideal-cut-f-color-vs1-clarity_LD03410584

It is slightly bigger at 6.10 mm, I like the slightly fatter arrows, too.

This one seems to have lower clarity... is that going to affect the fire and brilliance?

No. VS1 is more than high enough clarity.

Thank you so much. this is the first time I try to buy diamond online, if I decide to get this one is there anything else I need to ask them or make sure? anyother photos or certificates???

I think you are good to go. You can't go wrong with a F VS1 Signature Ideal.

sorry one more question. the one you pick for me has a 1.5 on HCA with two excellent and two very good. The first one I picked has one more excellent on scintillation. is this means mine has a better cut? I am so confused, they all ideal cut but why thay have defferent score on HCA??

You want the HCA to be under 2, and then you either get more information such as seeing it in person or a vendor's opinion, in this case they are Signature Ideals.

The numbers are almost identical, there is a very small difference. Between the VS1 and the first stone in your list, the pictures on the GCAL are better for the VS1. I don't really think the first or second should qualify under stricter standards of H&A.
