I have a question on ideal-scope images. For some diamonds, I noticed that there are two black spots between every two black arrows in the ideal-scope images. Do they affect the characteristics of the diamonds in any way?

Here are two diamonds (one with and one without the dark spots in the ideal-scope images) for comparison:

Diamond 1
Diamond 2


On a side note, considering all the diamond specs (inclusion plots, etc) and images, which diamond is a better choice to purchase for setting in a ring? Would appreciate comments from all the experts out there. Thank you.
 
I think both have been ''dug pout'' on their upper girdle facets and in this case i would ask one of the WF people to examine the girdle profile to see if that is the case.

The result improves contrast - but makes the stones look smallish
 
Those are both kicken ACA classics and I think Garry has been drinking again :}
Id buy either in a heart beat cut wise.
I might go for lower color and clarity to go bigger but cut wise Id take em :}
 
Hi guys.

Welcome our new camera/photo setup. We're shooting hundreds of images a day, still refining the process. I'd bet a Banjo Paterson these diamonds are typical ACA (no digging).

We'll take a look-see tomorrow to be sure, Garry.

2 more recent photos, top of this thread. The intensity is a little bit better (not perfect) but focal depth is still an issue.

We'll get better.

If the stones are good - then the upper girdles have lost their intensity John?
 
I''m surprised you switched to those photos. The focus borders on ''bad'' near the girdle. Must be even worse for larger stone?
 
Garry, I am new to diamonds and don't quite understand what you mean. Can you explain in more details? In simple terms, are both of them good or bad performers?

Just to clarify, the dark spots I mentioned are those near the base of the arrows. For diamond 1, there are several such dark spots whereas for diamond 2, they are few and between. Furthermore, I noticed that the ideal-scope image for diamond 1 looks sharp all round whereas the center of diamond 2's image looks more blur than the edges. Do all these differences affect the performance of the diamonds or am I just too paranoid?

differences in the photograph more than differences in the stone.
They both rock.

As storm says - it is a photo prob - not the stone.

Otherwise John, Storm and I are having an unrelated discussion.

WF will not sell you a pup.

I think you are referring to what is called watermelon seeds.

Experts: tell us about them please.
Does their symmetry matter?
I''ve seen a lot of IS photos in which the seeds are not all the same shape or size.

they are so tilt sensitive that telling anything by them isnt practical.
In theary you can tell about the faceting of the pavilion by them but its not practical.
Hopefully this doesnt bring back the 500 post all out fight on if you can really tell anything by them.
I think you can to some extent but it is not practical to do so at all.
Flipping it over and looking at the hearts and patterns is a much better idea.
 
Guys, thanks for the clarification.

I really hope that one of these diamonds will perform as well, if not better than a HOF. My gal saw a HOF and was completely mesmerized. Too bad, I can''t afford a HOF and the best bet I see now is an ACA from Whiteflash.

Btw, the HCA scores for the two diamonds using the AGS and Sarin figures are:

Diamond 1 (0.736, F, VS1): 1.4 (AGS), 0.8-2.3 (Sarin)
Diamond 2 (0.788, F, VS2): 1.1 (AGS), 0.6-1.9 (Sarin)

Sorry, a few more questions:

(a) Am I correct to assume that Diamond 2 is a better diamond since it has a tighter HCA range?

(b) The clarity plot for Diamond 2 shows a big patch of inclusions on the table. Will it affect the sparkle?

Thanks.
 
A> hca score difference doesnt mean one is better cut than the other.
B> inclusions wont affect the sparkle in a vs1 or vs2 to a noticable degree if at all
 
Id buy the second one if picking between them, slightly bigger lower price if that helps.

In my opinion HOF is a good middle of the road quality Hearts and Arrows quality cut diamond. There are many diamonds that will perform equally well and look as good or better than an HOF.

They have done a great marketing job and were the preeminent brand to push the H&A cut in this country, although I believe Gary Write may have actually brought them into the country before HOF. They were originally primarily cut for (and developed in) Japan, but when their economy went to heck the prices were lowered and they then began to be sold in this country. The folks at HOF added the sizzle to the equation and Zowie!

You will do very well with either of these two stones, so while it may be too bad that you can not afford a HOF, it is not too bad that you will be buying a stone of equal or superior beauty because of it. It only means that if you had the money to buy a HOF you could now buy one of these two stones and still have a lot of that money you would have spent...
