Hello everyone. This site has been an amazing resource, I feel like I should qualify for an honorary gemologist degree or something with all of the reading I've been doing.

I have been eyeballing this stone over at WF:
http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3034166.htm

but I'm a little worried about the crazy inclusion marks on the diamond report. I don't know enough about how to interpret the different types of inclusions to know whether or not what is shown on the report is a problem. I talked to WF directly and they told me that the stone is eyeclean from both the tops and the sides and that the inclusions were light colored.

Is this a good stone? It meets my requirements pretty well although I couldn't find an HCA score for it. I'm looking for 1ct F/G VS1/VS2/SI1 AGS triple 0. It is a hair over what I wanted to spend but... it seems like a great diamond.

Opinions? And thanks everyone for all of the posts here!
 
I'm not seeing any "crazy" inclusions. The only thing that stands out to me is the little dark crystal under the table at roughly 11 o'clock. Everything else does seem to be light colored as WF confirmed.

And it's hard to say if you can even see that little crystal with your eyes. WF's eye clean certification is pretty reputable and proven.

It's a 1.9 HCA, btw.
 
Thank you for the reply. By crazy, I mean they seem to be "long" inclusions to me. Part of this is my ignorance about inclusions talking. I just don't have a good feel for how to evaluate those.

Maybe I should just be asking folks here if they believe this is a good diamond. :wink2:
 
Would anyone mind giving an opinion on the diamond I'm looking at? I would very much appreciate it!

Inclusions
Those "long" inclusions are clouds, from what I see on the report. I am no expert. But I am going to guess that they look "long" because they are, looking from the top, more like streaks than blobs. The clarity is graded SI1, and that area of the diamond is very busy in real life, and WF rated the diamond eye clean. That would be eye clean enough for me. Also, I always zoom in on the H&A idealscope pic and the ASET pic, and look for inclusions there. A dark crystal often shows up on one of those if it's going to be visible without a loupe (thas is just my opinion and is not based on anything other than my own experiences.) I don't think clarity is a problem.

Diameter & depth might be something to consider.
Depth at 61.5% is a big deeper than the PS "cheat sheet" which sets and arbitrary cutoff of (I thing) 61.2%. All that does is perhaps make the diamond face up a little bit smaller diameter. 6.5mm diameter is what most people shoot for in a 1 ct. That depth might be why WF didn't put it in AGA and it's in Expert Selection instead.

Table
The table is larger than the 55-56% that I prefer but that's another personal preference.
 
I think it is a nice stone. The clouds are not affecting the brilliance but you might asK WF if they can see any difference when
comparing it to a VS stone. That might give you a little more confidence.

By the way...cheat sheet depth is 62% and for some it is up to 62.3% so 61.5% is just fine besides is an AGS000 which trumps.
 
I really appreciate the responses, thanks! :appl:
 
Todd Gray (he used to be a PS vendor and he's still on here with advice) has a site niceice.com and his "5 minutes to success" says:
Total depth between 59 – 61.8%
Table diameter between 53 – 57%
Crown angle between 34.3 – 34.8 degrees
Pavilion angle between 40.6 – 40.9 degrees
Girdle: thin, medium or slightly thick (or combination thereof)
Culet: GIA none or AGS pointed
Polish: GIA Excellent or AGS Ideal
Symmetry: GIA Excellent or AGS Ideal

That was the very restrictive short list of how to narrow it down when mostly what you have to work with is just the report or a data sheet. These things are ratios and proportions. The combinations of angles, depths, etc. have to work in tandem with each other. The HCA cut adviser gives you some indication of that. Search for "cheat sheet" here and there's a long thread that builds on that NiceIce short list and gives more information. Good Old Gold's site also has information.
 
Says eye clean which is 6" from the eye. You can call them for details but eye clean is eye clean
 
The inclusions on that stone, the plotting looks to have several very small crystal groups (clouds) along a line, They usually are clear and hard too see even with a loupe. I suspect the number of them, various sizes, location, etc make the clarity grade.

I would contact Whiteflash and have them review the stone with you while on the phone. Ask about the eye clean, what they see, the color of the inclusions etc.

It sure looks like a beautiful diamond.
