It''s a VS2 so it shouldn''t be noticable unless you have super good eyesight =).
 
with VS clarity it will most likely be eyeclean but I would stay away from that stone you posted bc its not the best performer with an HCA of 5
 
shouldn''t have a problem with VS2 inclusions,but the cut looks deep.
 
Yap, the cut is deep, angles is bad.
 
Hi abe

I wouldn''t be concerned with the crystals, this diamond is too deep and has steep deep angles also, it will look small for the weight and very likely leak light - you can do better.
 
Only a very small number of VS2 inclusions might be detected by an eagle-eye at a very close distance. Usually, you need to know where VS inclusions are located, before you have much chance of finding such a minute speck with the naked eye. Inclusions under the edges of the stone are much harder to find.

Being a scientist, I have an eagle-eye for detail and once I know the location of certain types of VS inclusions (mostly larger VS2 crystals, groups of smaller crystals, or feathers), I can just about detect "something" at a distance of about six inches and in the correct light conditions. But without the benefit of a lens to confirm that it really is an inclusion and not a minute speck of fluff, dirt, or just a strange reflection out of the diamond, I would struggle to definitively say that I'd found an inclusion.
I'd say that, even with my eagle-eyes and kn owing the precise locations of the inclusions, I would only be able to see about 20-30% of VS inclusions directly under the table and probably only 10% under the edges.

From a clarity point of view, I wouldn't have a problem with that stone. Despite my eagle-eyes, I am comfortable with every VS-grade stone I have ever seen. I quite like VS stones with some inclusions under the table (but not too many), since I can fairly easily confirm that I really have the stone listed on the GIA certificate - because I can find the type and position inclusions with a hand-lens and match them to the diagram plotted on the GIA certificate. It's a great way to have confidence that you have a genuine diamond, without the need for diamond-testing equipment.

However, the more I look, the more I see that these "steep-deep" "Excellent cut" diamonds seem to be cropping up everywhere!
It really does seem as if the cutters are exploiting, en-masse, a possible loophole in the GIA "Excellent" cut grade to bump up the weight of stones at the expense of beauty, for the benefit of their pockets.
 
What is the HCA?

What is a good width to depth proportion? (DoW has that one rated as a super ideal cut)

TIA!
 
Considering that other posters have already indicated that the angles are not the best, this is very liberal interpretation of ''super-ideal'', I would say.

Live long,

Holloway Cut Advisor, it is used as an elimination tool, stones scoring below 2 are worth further evaluation.

A good range to begin with for depth is 60 - 62% give or take a little. Table 54- 57/ 58%

And regardless of what this vendor is calling this diamond, it is not a super ideal cut.
 
HCA is here:

As I only recently discovered, GIA''s interpretation of what falls within the "Excellent" cut grade is quite generous. The GIA system is much more likely to award a higher grade of cut than AGS or HCA systems.

Many diamond cutters seem to be "playing the system" and cutting sub-optimal diamonds that they can just scrape into the GIA "Excellent" grade, while retaining maximum weight.
Send the stone to AGS and there''s a good chance that a GIA "Excellent" cut will be rated lower.
