Is this good? 2.35 ct J VS2

[cicero]

I thought I had foud the perfect diamond for my budget:

2.35 ct J VS2 from James Allen, it has an ideal cut. But the HCA score is not good: 4 . What is your opinion on this? I''ve asked for an idealscope they should send it to me soon. I saw the high def picture on their web site it looks good. http://www.jamesallen.com/diamonds/J-VS2-Ideal-Cut-Round-Diamond-1200344.asp

Thanks

Nope, much too steep in the pavilion angle for that crown angle, will have leakage in the IS image.

I was also a bit worried about the fluorescence but I read it wouldn''t be a problem with an J color. Is that right will it affect in any visible way the diamond?

Hmm, not a good news. How come a stone graded excellent cut by GIA gives such a poor HCA score?

The diamond is what we call here a steep deep cicero, both crown and pavilion are too steep and deep to work well together, this diamond will show light leakage which you don't want, in fact the leakage can be seen around the table of the diamond in the loupe image.

This is sometimes the case that the GIA Excellent cut grade allows less desirable proportion combos such as the steep deeps to get the Ex cut grade.

Strong blue fluorescence is not often an issue, check with the vendor if it causes the stone to look cloudy at all, this is unusual but best to check.

Well, I will continue my researchs then , thank you

Ask if it is not an overblue which will turn the stone milky/hazy in sunlight. Rare.

Most of the time, in the presence of sunlight or UV, the stone will look slightly blue. Personal preference if you like it or not. But again, probably not a good cut to begin with.

Hi, I might have found something ok

2.29 J-VS2 http://www.jamesallen.com/diamonds/J-VS2-Ideal-Cut-Round-Diamond-1200334.asp

It has a HCA score of 0.9

Can you help me read the idealscope, also i''m woried if this diamond is eye clean despite being vs2. The inclusions are visible on their website with their mignification, i''ve requested a high definition picture.

Thank you

The pavilion angle is a bit shallow which can cause obstruction, however from the IS image the diamond looks quite good - the longer lower girdle facets could help there along with the overall tightness of the cut, ask JA's gemologist to evaluate the diamond for obstruction. This is when a diamond visibly darkens at close scrutiny due to the viewer's head or body blocking light to the stone, the gemologist will be able to advise further. Sometimes such diamonds are better suited for pendants or earrings as obstruction isn't an issue in the same way as can be seen in a ring stone. So I think the image is favourable, see what the gemologist says concerning the above.

VS2 should be eyeclean but it never hurts to check, you can't go by images so ask the gemologist to check the diamond is eyeclean too.

I see a little obstruction; the arrow between 2 o''clock and 3 o''clock has a paddle. Paddles are the result of obstruction from what I''ve learned.

 

[stone-cold11]

On the verge of obstruction.

Thanks again for your advices. You are the BEST.
I just asked for a James Allen gemologist to examine it, but I wonder how much I can trust his answer?
Meanwhile i''m still continuing my research but IF this diamond has an obstruction should I reject it automaticly? I think it will depend on how perfectionist I am but from what you explained LORELEI I guess this problem will be very noticeable, is it?

 

[stone-cold11]

not really that noticeable. All stone will go dark, just depend on how much light you are blocking = how close you are looking at the stone from, I believe IS/ASET is set to mimic the condition when viewing about a foot away. To other viewers, it is not problem, it is usually the problem of the wearer of the stone.

No it won''t be very noticeable and especially when viewing such diamonds in person, to me it isn''t actually a huge deal anyway, you only see it when bent over the stone which isn''t an angle I use for admiring the sparkle as I think most tend to hold the hand away and upwards to enjoy the performance, plus the Idealscope is fine, my opinion is no need to worry too much but check with the gemologist to see what they think.
