Hi there!

First off, welcome aboard!

I suppose the SI1 inclusions aren't too big a concern at .81ct, especially with an AGS lab report to warrant it.
What concerns me a bit is the pavilion depth, which is, in my opinion, a bit shallow. Have you seen the stone in person or, at least, do you have any picture of it?

I''m a bit concerned about a few things....

The graphics/tables you''ve posted don''t look like anything generated from an AGS report that I''ve ever seen. I''d try to get a copy of the complete grading report.

Second, as Giangi mentioned, the pavilion is quite shallow. I personally don''t believe this stone would qualify for AGS0 cut grade, but as I don''t have the software, etc., I couldn''t say for sure. That doesn''t mean it doesn''t have the potential to be a beautiful diamond, but you should know if the stone warrants the premium that AGS0 stones command.

I agree, see if you can get a picture of the diamond to get an idea, it might look great and at least that way you will get an idea.. The pavillion depth might be a concern, it might not.

Thanks glad to be here!

I have seen the stone in person, but my novice eye doesn't know right from wrong. It looks great to me, and looks very nice in the H&A viewer, but again I am a rookie at this stuff so I really haven't a clue at what I'm looking for exactly. I have looked at tons of stones but they are all starting to blur together.

I have looked under a 10x microscope at it also, but do not have any pics. What would be a better number for the pav dep?

The report that I posted wasn't an AGS report it was a sarin report that the jeweler ran for me. I do have a copy of the AGS cert in front of me though. I don't like how the serial number has been whited out. The jeweler didn't do it, but his diamond guy must have when he faxed it over to him. Is that commom?

EDIT: I just looked at the AGS cert and the pavillion depth on there is showing at 42.2%. Maybe his sarin machine is just a bit off?

Well, the HCA says you might indeed find it pretty!

Factor Grade
Light Return Very Good
Fire Excellent
Scintillation Excellent
Spread
or diameter for weight Excellent
Total Visual Performance 1.3 - Excellent
within TIC range


Have you seen any other stones with more "ideal" numbers to compare it to? If you haven''t, I would try. If you have, and can''t see a difference or find this prettier, go for it!

 

[Giangi]

I have seen "blanked" cert numbers again. I suppose the dealer whited it for privacy issues. It should not be a great concern.
To answer your questions, you''ll see that the great majority of stones liked here have pavilion depths ranging from 42.5% to 43-43.5%, or about 40.5°-40.9°. It really depends on many factors though.
The fact you have been able to see it in person is great. Did you have any other diamond to compare it with? Was this one the brightest?
Truth to be told, this pavilion depth doesn''t make me too confident in the stone. Have you had a look at the inventories of internet vendors? I ran a quick search and it looks like your specs are easily found at comparable price. Just an idea.

I have seen it next to a 1 ct stone that was similar, but it had many more inclusions, so I didn''t give it a very thourough look. They both appeared to be about the same in the brightness category.

I have done a lot of looking online, I''m just very hesitant to buy without seeing it live. There is a similar stone (.821, F, SI1 for $3450) at niceice.com that I have been thinking about.

 

[Lorelei]

niceice is a great vendor, can you post the link or info of the other diamond for comparison''s sake? Online vendors normally have a good return policy, so if by some chance you weren''t delighted you could return it.

Maybe his Sarin machine is really off. The 40.1 degree pav angle looks really shallow. The machine is supposed to be accurate to +/- 0.2 degrees and even then the diamond still looks shallow. What is the pavillion and crown angle reading on the AGS report? Can you post all the stats on the AGS report? diameter, angles, etc. I would be interested in seeing an AGS0 with a shallow pavillion angle. Thanks. The stone looke good to you. No problems with dark pavillion mains (dark arrows) when you look at it close?

 

[amtrak23]

Here is the full AGS cert. It's ugly because it was faxed to the jeweler, emailed to me, and now scanned. Make sure to magnify it in your browser so you can red the garbled text. Hopefully it's big enough!

AGS Cert

Here is the stone at niceice: Niceice .821ct

let me know your thoughts on that guy please. I don't have a link or any better info for the diamond that the jeweler has.

Whatmeworry: I tried searching for dark pavillion mains, but didn't find a good representitive photo? Is this what you mean? Dark pav. mains?

When I say the H&A's looked good they looked nowhere near what they look like in that link.

EDIT: I put a lot of weight in how the H&A's looked. This guy at goodoldgold has some very nice H&A's. If the one that my jewerler showed me looked like that I would have bought it by now. GOG H&A's
How wrong is my thinking?

Okay that makes more sense, it''s an older AGS report. BTW you can probably get the serial number from the diamond itself because according to the AGS report, the diamond is inscribed with the serial number. So look at the girdle of the diamond with the microscope and you should be able to read the serial number. Yup those are the pavillion mains. The reason I asked is that with lower pavillion angles/lower crown angles there is a worry that the arrows can really stand out and the diamond may look darker. See for example

http://diamonds.pricescope.com/ideal.asp

but if you''ve seen it and didn''t even notice then no worries.

Niceice looks like they carry some really gorgeous diamonds and it seems like Niceice is really fussy about the inventory they carry. So it''s definitely worth checking out.

H&A viewers tell you about symmetry but that''s not the whole story. They can''t tell about light leakage. Actually the niceice website has an article on why H&A aren''t the end all. Good luck!
