Need help deciding between these diamonds

[aadiamond]

Hello,

I have a small budget and my heart is set on a good 1 carat diamond. I found some online which look pretty good but wanted to get some input from you guys. Both my girlfriend and me are completely new to diamonds and we could not tell the difference between a F/I or VS1/SI1 when comparing at a store so I thought a bigger size for an eye clean I SI1 would be a good trade-off.

1.07, Spread 6.50-6.54x4.05, HCA - 2.0, I SI1 Excellent cut

Pricescope price - $4624

1.05, Spread 6.48-6.52x4.04 , HCA - 1.9, I SI1 Excellent cut
http://www.eternitybyyoni.com/diamond_detail.php?id=718521
Pricescope price - $4538

0.96, Spread 6.33-6.36x3.90 , HCA - 0.7, H VS1 Excellent cut

Pricescope price - $4495

Are these good choices ? Also if you guys have pointers to other/better 1 carat diamonds in the same price range it would be really appreciated.

If I should be looking for higher quality and smaller diamonds with my budget do tell.

Thanks.

Those 36 crown angles will result in more fire in certain lighting, but at a cost in other areas. For example, the 1.05 I SI1 scored this on the HCA:

Light Return: Very Good
Fire: Excellent
Scintillation: Very Good
Spread or diameter for weight: Very Good
Total Visual Performance 1.9 - Excellent
within FIC range

I personally like Excellent on light return and scintillation. Most ideal cut stone score vg on spread, so that is not of concern.

The .96 H VS1 would please me more with color and clarity, but I'd need to see some images of the stone due to them rating it very good instead of excellent on symmetry. I think Yoni will provide idealscope images, so I'd ask for one for this stone.

Larger crown surface area on the last (0.96) given same crown height and smaller table is my preference, all else equal... no way to tell if all else is equal without more info though, so ditto DS - get more info & vendor's opinion.

I checked with Yoni and he could not get me the images. Since the 1 ct do not fall in my budget I have decided to go with good 0.8 ct. I am down to the final three which are very close in performance and any input as to which one I should go with finally would be really helpful

0.81, HCA 1.1, H SI1, Ex/Ex/Ex, H&A

0.82, HCA 1.5, I VS2, AGS 0 Ideal, H&A

0.81, HCA 1.6, I VS2, Ex/Ex/VG
ERD diamond

I have the idealscope images for all three but am not sure how to upload them but will put them on as soon as I know how to. All three are priced very similar so which one seems like the best one ?

Thanks in advance.
