DiamCalc for 2.6ct???

[MrNyceGuy]

Would anyone be able to run a DiamCalc GEM file for the following diamond I am considering buying from a recommended online vendor? I''m trying to see the output from the GemAdviser on the diamond but the free version of DiamCalc will only show a Marquis. ALSO, any opinions on the diamond are VERY welcome and will help me to make a decision

. Thanks so much!!!!!

Here are the stats:

Carat: 2.59ct
Color: H
Clarity: SI2 (Totally eye-clean

)
Pavillion Depth: 42.5%
Crown Depth: 14.9%
Table: 57.5%
Crown Angle: 34.7%
Pavillion Angle: 40.5%
Culet: None
Measurements: 8.81 x 8.86 x 5.37mm
Fluorescence: Negligible

Hi MNG.

The info does not allow a DiamCalc prediction of any more usefulness than a HCA score. The given angles are averages of multiple numbers (crown angle 34.7 is an average of eight measurements for example) as are some minor measurements that are missing. Cut precision, girdle details and optical symmetry variations aren't accounted-for in numerical lists either. All we could do with this data is create a model with perfect wire-frame symmetry & some improvised measurements, and though that would be a nice picture it would not be representative - and could be misleading.

An actual ideal-scope or ASET image would allow meaningful comments.

Hey John, thanks for the reply. I''ve seen many of your posts on here and you''re always honest and helpful. As you mentioned I have attached a picture of the idealscope and ASET images. The symmetry is "Very Good" so you can obviously see how the arrows do not come together perfectly. Is this bad? I know it''s not a H&A but how much will this effect the visual performance of the stone to the naked eye?

What is your professional opinion given the stats I posted above and the following images? If I''m not mistaken I think the diamond is slightly shallow although not too much to cause fish-eye. Your thoughts?

Also, I''ll post a Sarin report to provide better info.

Thanks!

I dont like the dip down to 40.2 on the sarin.
It is likely too have contrast issues.
Have Brian eyeball it while talking too you on the phone.

Storm you know that is a silly comment.

I guess I''m a bit confused as to whether this is a bad thing, and whether the diamond has good stats or not. Also, are the idealscope/ASET images good? Any help is appreciated.

shallow pavilions in the 40.5 range and under can have some issues but not always.
Dipping down to 40.2 it needs to be checked.
Have Brian check it and talk over the stone with you.

how so?
depending on whats in the range it might be an issue.
If the majority of the facets are in the low range.....
Having Brian check it is good advise.

MNG - Thanks for the kind comments. I didn''t realize that we were the source...so...you have your ideal-scope and ASETs.

You can trust your rep''s comments and if you''d like input from Brian we''re happy to provide it. As you have noted it is a very clean SI2 and a lot of diamond for the money. We advise using a skilled setter for the stone because of the small feathers and the natural. It''s on the shallow side of "ideal" but has no performance issues. We won''t recommend a diamond unless we feel its a top performer and worthy of our lifetime trade-up benefit.

Haha, John I didn''t even realize you worked for WF at first. My WF sales rep has been very helpful thus far although I was not able to speak with Brian at the time of his review of the diamond. I had the stone shipped to a local appraiser today so that I can get it appraised tomorrow while I''m there in person. I think that will help me immensely with my decision. I know WF has a great reputation and the lifetime trade-up policy is very useful. Thanks for the advice all. I''ll let you know what becomes of it after the appraisal.

Just wanted to update. I had the diamond appraised by Toby Smart at JustAppraisers in NYC today and upon seeing the stone in person I fell in love. It''s a really stunning rock and I can''t wait to have it mounted. Thanks all for your help and advice. I''ll post pictures in a month or so once the custom setting is made and it''s all done.
