which diamond to choose?

[timotheo]

Hi guys,

I wanted to get your opinion on two diamonds I am looking at. Assume that the price point to be the same, should I go with:

1) http://www.gia.edu/cs/Satellite?reportno=2171089961&childpagename=GIA%2FPage%2FReportCheck&pagename=GIA%2FDispatcher&c=Page&cid=1355954554547

or

and why?

Thanks,
Tim

I honestly would buy neither, as I would want stones with more ideal proportions. Both stones have extremely low crown angles, for one thing. The first one, with a 60 table and 31.5 crown angle, would be fairly flat topped and not very appealing from the profile view. In addition, it could be more prone to chipping. It gets a 3.7 on the HCA screening tool, and we generally recommend stones that score cloe to or less than 2.0. The second one does get a 1.9, but it gets very good on light return and scintillation, and normally I like to see excellent on all but very good on spread. Of these two, the 1.74 is the better risk, but again, I would keep looking.

These are parameters that are more likely to get one into ideal cut territory:

table: 54-58

depth: 60-62.3

crown angle: 34-35.0

pavilion angle: 40.6-41.0

I would have to agree with Diamondseeker's comments on the cut of these two stones. Is there a particular reason that you are looking at VVS clarity stones? You could certainly drop down to VS clarity and save some money or even buy a larger stone for that matter. E color can be a bit of overkill too unless you are partial to colorless stones. Her recommendations on numbers will generally net you a very nice stone.
