i can''t see the numbers on the report

but i can tell you that if the girdle is at least ''thin'' it won''t get an ''excellent''
it could also being the brillianteering on the facets but i think they are reporting that now, so you would see that under the comments section if it were to apply.

Yep, you called it, Belle...very thin girdle. I''d personally avoid that as they are more prone to chipping. You could always ask for them to examine how much of the girdle is very thin, though. And if you are setting it in a bezel halo, it might not matter...but you should ask about that specifically.

 

[tlow]

Yes, it does have a very thin-thin girdle...so what ds says makes sense and I will definetly check that out. Does AGS grade in the same fashion concerning girdle thickness...meaning if this were graded by AGS it would probably get and AGS1?

 

[diamondseeker2006]

I believe it cannot get AGS0 with a very thin girdle, but you''d have to look at the qualifications for an AGS1 to be sure about that grade.

I don't know that I would totally 'avoid' a v-thin girdle...it depends on where it is v-thin and how much of the girdle is v-thin. I actually prefer a thin girdle to anything else, but v-thin in too many places COULD be an issue. But you should get more information before just dismissing it considering that the specs on the stone are pretty stellar otherwise. REALLY love those #'s otherwise.

Also if you plan to insure the stone anyway, a v-thin to thin girdle may not bother you at all.

Tlow,
Tell Jim about the girdle and he should be able to assure you about your choice. My diamond is like this, it all the proportions for a GIA excellent cut, the only reason it is not is because the girdle has a very thin spot on it. This makes is Very Good. Now if a lot of the girdle is very thin that''s not too good. However on mine the very thin part is very small and it made the diamond extremely worth it. It has an excellent cut to it. I actually liked it better for some reason than the AGS 000 that I looked at. It scores well on the HCA. Looked good under an Idealscope, and is an all around excellent stone. So just ask him how extensive the very thin is!

AGS 1 ding for V thin (need girdle measurement to be sure)

Mara makes very good points here...I''d definitely get it checked out before dismissing. It has awesome numbers and could be a great buy!

I agree with DS but if you are planning on setting it in a bezel halo then it really won''t matter b/c it will be protected by the setting. Definitely ask Jim about it b/c it looks like it could be a gorgeous stone..

It has great proportions and the nice thing about the cut grade is that a VG is slightly cheaper than an excellent, but you are getting the same visual appearance. I would definitely consider this stone, but put it in a more protective setting and without a doubt purchase insurance. You could also have Jim send it to an appraiser to see the likelihood of a chip.
