I have heard that H&A doesn't mean that the stone will reflect more light. I have narrowed down to 2 diamonds and cannot tell which one would be a prettier diamond. Can someone help me?

choice 1.
http://www.bluenile.com/diamonds_details.asp?pid=LD00916542
Choice 2
http://www.bluenile.com/diamonds_details.asp?pid=LD00310166

Choice 1. Blue nile Ideal signature cut
F VS1 1.19 6.80 x 6.82 x 4.18 mm
Table % 56 Depth% 61.4%
Angles 34.8 and 40.6
symmetry/polish ID ID
Girdle: Think to Slightly thick, faceted
Cutlet: pointed
Fluroescence: Negligible

Choice 2 GIA ideal cut
F VS1 1.20 6.94x6.91x4.15 mm
Table % 58 Depth % 59.9%
Angles 34 and 40.8
symmetry/polish EX/EX
Girdle: Thin to Medium
Cutlet None
Flourescence None

1. Which one would reflect more light or brilliance?
2. Which stone would be a better value & fairly priced?
3. Does the table difference here make a difference?
4. Is there a way to calculate ideal angles based on the measurements?

thanks!!
 
These days, I wish I had DiamCalc...

I answered your first Sarin thread.
 
Or you could play with this one: http://www.goodoldgold.com/diamond/1936/

Helium scan (tell you more than you want to know)
Sarin scan
.gem file generated by Sarin scan (must download GemAdviser to read .gem)
DiamXRay image
magnified images
hearts and arrows pictures

have fun!
 
F VS1: http://www.goodoldgold.com/diamond/705/

you could play with two .gem files at the SAME TIME, even!

Thanks guys, but I thought that H&A doesn''t mean that it is going to reflect the most light? In this case the choice #2 will not be as pretty as choice #1?
 
H and A does not mean that it is a more brilliant stone, but it DOES speak about a certain precision in craftsmanship. Superior craftsmanship, as well as accuracy of cutting to ideal standards, is what creates a brilliant stone.

And, personally, I would never pay 10K for something of which I have not even seen a PICTURE.
 
Well w/ 30 day return policy there''s enough time to return it if I am not happy w/ it. Plus it seems from all the places I went to, ave cost would be 30% higher for the same stone including tax. It is kind of hard to ignore that kind of savings even if the service is superior.
 
The F VS1 I gave you on GOG's site is just 20 dollars more (if you pay by wire, check, whatever) than the Blue Nile one...surely it costs a lot more to do an in person analysis of each stone, take Ideal scope, H&A, and magnified pictures of it, and scan it with four different machines, rather than having it just sit at the supplier and uploading information into a database.

If you insist on BN, I will try to find something for you a little better.
 
O can you? that would be great. Its not that I insist on BN but I would get 10% discount w/ them as an extra incentive. That would be 1k for a 10k diamond. I know $ is not everything when it comes to a diamond but I am trying to stay in my bf''s budget too. thanks!
 
Oh, didn't know you would get 10% of BN. The first stone is a good choice.

What is your budget, what size (a range) do you want?
 
Actually a lot of people probably have it & don''t even know it. It is called Corporate perks. Many companies offer it but people just don''t really read into it. Who ever has it can also provide their discount to 2 people of their choice.

My budget is 10-11k for the stone so I am hoping to at least get a 1.10-1.2 E or F VS1 ideal cut diamond. I am not sure if I needed to be H&A but brilliance is definitely my top priority. Choice #1 I am a little concerned about the girdle since part of its thin or should I be?
 
Thin girdle is fine.

and 10% off of 12225=11K, so does that mean I can pick something 12225 off of BN? Or is 11K with discount your top budget?

ETA: I like the first stone you picked. The 1.19
 
Actually I found this one. Is it better you think? I think I would forget BN and go for the prettiest diamond instead.

That looks like one heck of a diamond to me.
 
DG, in your other post you asked if 0-1 HCA needs to be "checked out." I got an HCA score of .8 (which is fine) with the GOG F VS1. With GOG's eyes and the pictures and doodads, that is checking it out. HCA is used to weed out the bad stones when you don't get to see them in person.

I don't see where it says VS2...but the AGS says VS1 and that is it's official clarity grade. Sarin doesn't grade clarity...just measures proportions.

I'd go with the GOG stone, as the WF stone is a different style, and it's sort of a love it or hate it thing.
 
Greetings,

It''s not my practice to hop in threads where a stone of ours is being discussed but when I went to that diamonds page I did note 2 things that are currently being corrected.

1. The Helium Report for that diamond is of the actual stone but my lab assistant made a typo on the clarity. It is a VS1.
2. Not long ago we had another diamond exactly the same weight, a 1.178ct F VS2. On the Report tabs on that stone (on its webpage) the Sarin Screen Shot (showing the GIA FacetWare results) is correct showing the right data, however we had mistakenly posted the 3D Sarin file of the other stone. As I type this my lab assistant is correcting it and putting the right Sarin file there now.

while I''m typing ...

The .5 HCA score has been checked out by us on this stone. What strmrdr said in the other thread is accurate. While we do not consult the HCA, it is important to realize that many stones that fall under the 1.0 score oftentimes do not reflect trade opinion regarding "ideal" status or light performance, but only one man''s opinion, Garry Holloway. Garry is respected by all here and I also sympathize with his stand on shallow cut diamonds but its important to note that the HCA (developed by him) reflects many of his own personal tastes which in many instances run counter to even some of the more conservatives labs opinions (including GIA and AGS). Same goes with the spread factor. Last I checked I think anything with a depth higher than 60.5 took a hit for spread. Some of the most beautiful stones we''ve ever laid eyes on have depths greater than this, generally in the high 60''s, 61.x range and even the low 62.x zone so don''t be discouraged by a "very good" spread factor on any stone ran through it.

Kind regards,
 
Thanks Julie, these 2 stones both scored the same on the HCA so I didn''t know if the price difference was really worth it. Of course I want to be able to own the prettier stone. Its been a LONG 3 months of stone searching for me but I finally found it w/ your help!!! thanks so much for everything!

i would have to disagree about the differnt style ''love it or hate it thing'' and i would challenge anyone to decisively pick between the two in normal lighting conditions.
i''ll double down for anyone saying that they ''hated'' one or the other. both are top cuts with only slight, perhaps even udetectable, differences between them.
 
Here's WFs description of the two styles: http://knowledge.whiteflash.com/Q10253.aspx

Classic: "intense, on-off look to the scintillation"
New: "robust, broadfire scintillation"

intense vs. robust?

perhaps a little too florid.
 
HI Rhino, Actually Tim let me know too that the Helium report is wrong but thanks for providing this information. It''s very helpful to learn more about the spread.

I just hope I can convince my bf to reserve the diamond for me in time
