Hello all I am in the market for a center stone here are my two options:

Stone 1

Shape: Round
Carat Weight: 1.67
Color: H
Clarity: VS2
Graded By: GIA
Cut Grade: Ideal

Depth: 61.7%
Table: 55%
Girdle: Thin to Medium
Culet: None
Polish: Very Good
Symmetry: Very Good
Fluorescence: None
Measurements: 7.68 x 7.61 x 4.72
Price$ 12600

Stone 2

Shape: Round
Carat Weight: 1.64
Color: H
Clarity: VS2
Graded By: AGS
Cut Grade: Ideal

Depth: 62.5
Table: 52.9%
Girdle: Thin to Thick
Culet: None
Polish: Ideal
Symmetry: Ideal
Fluorescence: None
Measurements: 7.51 x 7.55 x 4.71
Price$ 12,300

My only concern on stone two is the table %. The AGS report call this a triple 0. Both of these would be online, thus I have not seen the stone.

TIA.

Welcome


Can you add the crown and pavillion angles please, so we can tell more? These will be on the grading report. The only other thing is as you mention the 52.9 table, but get the other measurements if you can, interesting to see how that one pans out, also with the ID ID polish and symmetry.... Also see if the vendor has an Idealscope image for these, that would help. Also the second looks as if it is facing up a little small for it's weight, see what the girdle measurements are too, weight could be hiding there, this looks more like a 1.55 thereabouts.

gia does not have an ''ideal'' cut grade. this is not an ''official'' indication of cut grade.
actually the highest cut grade this stone could have received from gia would only be ''good'' because of the polish/symmetry ratings.

i have a feeling that this stone would not be ideal under current ags standards but we would need more information to be sure.

Ditto.

So far, #1 is looking like the better of the two, it also faces up bigger. But we should get all the info first.

I think that #2 has an old cert because it says ideal and does not give the light performance. It also has such a small table. The thick girdle also causes #2 to face up smaller than it should, so I''d eliminate that one. And as Lorelei said, we''d need the angles to really give an opinion.

The info should be on both the AGS and GIA reports, but if the GIA is an older report it might not be shown, take a look. You might see a diagram of a diamond with numbers and %''s detailing it, the crown and pavillion angles should be there.

Belle, why would you say that? Very good and Very good can fall under the "very good" cut range, can''t it?

I spoke to the vendor on stone 1 and was told that GIA does only provides crown and pavillion % on Brillant cuts is this correct ?

Should be angles. If this is an old report then it won''t have them, newer ones do. Does he have access to a Sarin machine to run a report on it? That would give us the info.

No, that is not correct, unless this is some kind of really old cert (and I don''t know how old ones present the info). That may be the case if the stone does not have a cut grade. Ask him if he can give you an ideal scope picture so you can check out the symmetry yourself (if this is local). If it is not local, I''d suggest broadening your search.

Cut Grade on the Cert is Excellent. I just wanted to say thanks to all who have taken the time to answer my questions.
