    I don’t think anyone is going to really be able to tell you based on that information alone which is the most beautiful, sorry.

    Cut this post, and paste it in a post at Pricescope.com (In the rockytalky subforum)

    They will be able to help you, or suggest alternatives!

     

    Edit: I see you already have! They are genuine pros at selecting diamonds (much moreso than here on WB)

    1, 3 and 4 have fantastic color and clarity. All the HCA overall scores are good.

    I would forget 2 because its clarity is so low. The difference between VVS1 and SI1 is huge.

    To choose between 1, 3, and 4, I would suggest you look at things such as the presence of fluorescence, girdle thickness, culet size, and HCA subscores (you want all those to be excellent, too).

    The very best thing would be to see it in person, (well, even better would be to both see it in person and to scope it to check out the hearts and arrows) but, the chances of getting an unattractive diamond that is, (I assume GIA-graded) D-E in color, VVS1 in clarity, and has an HCA score below 2, are virtually nil… it’s pretty much guaranteed to be a stunner!

    Sounds like you’re going to get a real beauty, OP 🙂 I hope you’ll share pics with us once you have it!

    Yes, and also could be a durability concern if it is near the girdle.

    With VVS1 the inclusions should be so small they don’t interfere with beauty or durability, so I am not concerned about the feather in #1.

    I can’t really advise you on size, 5.8 does look larger than 5.5 but not by much… in fact, it is almost equidistant in size from 6mm, but remember that moissanite is a different material with different properties, and because of its very high refractive index, it will tend to look larger than a diamond of the same diameter (and, it just “catches attention” in a different sort of way because of how it behaves, hard to put into words…A high quality diamond is very active, I don’t want to imply otherwise…and a moissanite is very active also, but in a particular way, which could be what threw you off, some people find it too “busy”).

    Your best bet is to go to some local stores and try some diamonds on in the sizes that you’re thinking of. Of course, if the quality of those diamonds is lower, they will look somewhat smaller than diamonds with the specs you are considering, so try to take that into account. I think it would still be helpful to do, even so. Familiarity always helps!

    I would chose #2, only if the feather is located in a place where a prong will cover it. If it cannot be covered by a prong, or you’re going for a bezel setting that will highlight the flaw then I’d go with #4 if price is not an issue.

    @Sanibel13:  No one can tell you without looking at it. Have you got a good returns policy on this diamond? You can always return it to the vendor if you are dissatisfied with it when it arrives.

    You really need to ask for an Idealscope, ASET, etc. for each of these contenders to have a real idea of how well they perform.

    Most people can’t tell the difference between D-F so you will be paying a premium for a D-coloured stone that you might not even be able to appreciate.

    Yes, there’s a jump from SI1 to VVS1 but plenty of SI1 stones are eye clean and often people can’t detect flaws from VS2 upwards. Again, you’re paying for a real high clarity and apart from you knowing its very pure and clear, it won’t make a great deal of difference to your enjoyment of the stone.

    Cut has the biggest impact on beauty, in my opinion, and all of your stones are apparently well cut. You cannot know which is the best without asking a gemmologist to review them, having further tests run (Idealscope, ASET, and so on) or, indeed, seeing them yourself.

    Can you provide any more information about the 4 contenders?

    I’d look at some other vendors too if your vendor can’t provide you with any further details about these diamonds. James Allen, Good Old Good, Brian Gavin Diamonds, Whiteflash, etc. — all of these provide information about their diamonds so you can be sure you are choosing a good one.

    OP – what’s wrong with your current ring, out of interest? It looks nice from this picture you posted on another thread.

    @lunalyra:  SI-level inclusions, “eye-clean” in particular, affect lightpaths, which affects performance. Why get a perfect cut that aims the light just right, only to cancel it out with inclusions blocking and redirecting its paths? Perfect cut assumes perfect clarity, and whole that may be out of budget, VVS1 is so lightly included it couldn’t make much of an impact. But as you go lower down the scale, inclusions are going to be more and more of a factor in terms of lightplay.
