IS interpretation

[climbman]

I''m curious to hear detailed thoughts on the following two diamonds, for which I am including the GIA certificate and Idealscope image. I am interested in details about strengths and weaknesses. Additionally, how would these compete with "super ideal" cuts as can be found on JamesAllen, BlueNile, BrianGavin, etc.

Diamond 1: ~$7,300

Oops. Diamond 2 ~$6,800

Diamond 2 has the best image, but having said that the first image is no slouch, you can see a tiny area of leakage but this might not be perceptible in real life, I would pick the second however if it was for me.

 

[stone-cold11]

I prefer #2 too.

 

[climbman]

Thanks. What indicates leakage here? Is it the extra black colored arrows in the inner ring / table? To my eyes #2 has nicer symmetry than #1, but I like that #1 is D colored. Would this influence your choice?

How do these compare to a diamond like the following?:

Look just past 12 o'clock on the first image and you will see a small lighter patch, that could be leakage but even so it is very minor and not something your eyes would ever pick up, the image is also slightly tilted which could be exaggerating it. It is still a great diamond.

The diamond above is also excellent, they are all comparable. The one linked above is a h&a so hearts images would need to be requested if you were interested in this one.

 

[stone-cold11]

If you want the D then go for it, the leakage is almost impossible to see in real life.

The GVS2 looks good.

 

[climbman]

Sorry, are you talking about #1 (the D VS2) or #3 (the G VS2)? When I look in the 1 o clock range on #1, I see "extra black arrows." Is this the leakage? Thanks.

Yes with the first image between 12 and 1 there is a tiny lighter area, thats what I am referring to.

 

[climbman]

Okay. So what do those extra black marks indicate? Is that a strange angle on a cut or something? Am I explaining myself adequately?

Yap, think the cutter did some digging/painting to the lower facets, probably to remove an inclusion that would have seriously affect the final clarity grade of the finish stone.

This help?
The defects in cut would not be very obvious to the naked eye.
The hearts cant be seen face up but the areas pointed to give an indication of what is happening with them.

Thanks for the graphics pal, nothing to do with girdle treatments or digging/ painting but a defect in cut precision?

 

[climbman]

Wow, great! Thanks so much for taking the time to help out! So, again, the ultimate question: how to choose? The G VS2 from JA above is in the same price range as the first 2, and has H&A. Alternatively, the F VS2 below is a bit more (~$1,500) with H&A. Is #1 or #2 close to either, or will the H&A and leakage difference justify buying either #3 (G VS2) or #4 (F VS2 below)?

Sorry to keep asking, but this is ultimately what matters. I have narrowed down to what I''m looking for, and deciphering the nuances as a complete novice is hard.
#4:

#4:

With the first diamond a hearts image is essential due to the Idealscope image if you want a h&a stone in view of storm's evaluation.

Diamond 2 definitely has potential and the one you added below also looks promising.

 

[climbman]

#4

 

[stone-cold11]

#4 should be good.

Ya, what is happening there Strmrdr?

 

[climbman]

my feeling is that they should all be "good." are any "great?" do any stand out? if not, why not pay a little less (#4 is 1,500 more) or perhaps opt for color? my first concern is cut, but i''m not hearing that the difference among these 4 is really going to be noticeable. does one of these really seems stronger? if so, i''d go for it. thanks!

vartions in the lower halves/girdles.
likely variations in angles, yaw and different depths.

 

[strmrdr]

If I am following the pricing right #2 would be my pick and put the ~$500 into the setting.
The g/vs2 h&a would be my second pick assuming the hearts check out.
Since h&a is claimed I would want to see the hearts image which JA provides.

Yaw is digging/painting right? Or are they different?

Painting and digging there is angle variations when measured up and down where yaw the variation is side to side.
This is extreme but a facet can be | when viewed across the facet side to side and painted or dug. Yaw is where the facet is angled side to side / but can be | up and down.

thanks!!!
btw better cutting tools that control yaw is one reason there are more h&a diamonds on the market and average diamond cut has improved with regards to optical symmetry.
Which is also why today more so than ever having hearts isn''t a guaranty of performance.

Most welcome my friend and thanks for all the help!
