Hey guys,

Im looking into a stone with a 34 crown angle and 40.6 pav angle. 59.2 depth, 59 table. its around 1.5 carats.

it gets a .9 on the HCA and a 1B on the cut class grader. The store says its a hearts and arrows.

Ive read that a shallow stone can cause obstruction issues. I am wondering if this stone is a good buy.

I want great brilliance, fire, scintillation etc...

What do you guys think?
 
We need pictures to see that (IdealScope, ASET, ...).
There are too many factors that we don''t know (minor facets, painting, ...).
I''ve had a 34/40.4 in the past, it had obstruction because the lower girdle was slightly painted.

Welcome!

Ditto Stephan, Idealscope is really needed. It could be perfectly fine or it might not, this combo is borderline shallow. If you have seen the diamond in person, view it close up to see if the diamond darkens or shows any signs of obstruction. This video bottom right titled Head Obstruction by Garry Holloway shows what to look for.

Also if this diamond is being sold as h&a by this store, can they provide images such as hearts images and arrows to substantiate this claim? Whatever you do, see if you can check this diamond out away from the store lighting to see how it will behave in everyday lighting conditions. This will give you a good idea how it will look when being worn on the hand.
 

AGS would say it is just the wrong side.


I disagree - they used 8 - 200mm inches viewing distance for an average head size. I think apart from when you buy a diamond - you rarely look form that close.
Aslo shallower stones are less effected by dirt.

And what most of us are interested in is a diamond that is noticed from the other corner of the room, 20cm is not a distance to admire diamonds (40cm is much better).
 
hey guys,

well, ill work on getting the idealscope and H&A pics, but heres a magnified veiew of the diamond. not the best shots, but its better than nothing. maybe

what do you think?

thanks

I can''t see the H&A picture, but I can see the inclusions.
SI2?
 
i dont have any H&A pics yet, but this is magnified quite a bit. its an Si1 stone. supposed to be a good SI1. i would imagine this is mangified more than 10X

im just more or less worried about the obstruction factor for now...

can you tell from this picture if theres an obstruction issue??

thanks

I don''t think so.
If it''s eye clean, it would be a fine diamond.
 
I think it looks nice from the photo.
 
ok, so since im so new, im taking these last couple comments as a "no, i wont have obstruction issues with this stone"

is that fair to assume?

thanks all!
 
I think you won''t have obstruction issues...

I think take a good look at the diamond, check it out at close range, if it doesn't visibly darken and you check it out away from the store lights and you like it, you should be good to go.

40.6 is generally safe but in some cases where the pavilion range is wide it can be an issue. 40.6 is just an average and in the case of GIA badly rounded.
Is the 40.6 off a gia report?

Also it is going to tend to the bright side over fiery with the large table and shallowish angles.
 
yep, i understand that it will be a bit brighter than firey... But, i wonder if it will have "poor" fire? i mean, the HCA said excellent fire and it is a GIA EX cut grade. (Yes, its a GIA, so it is rounded, but with the ex symmetry and cut grades, am i wrong to assume that it cant be that bad... ie 39.6/41.6 all over the diamond)?

And, to clarify a question above, i havent see the diamond yet. its from union diamond and i know some have mixed feelings about them (others have good experiences... and im one of those... my second diamond with these guys. great service in my opinion)

thanks guys
 
The fire won't necessarily be poor, the diamond suggests it will tend to be more bright and brilliant than fiery but you could well see some fire certainly.
 
Under spot lighting, many shallow diamonds show more fire and scintillation than others if properly cut.
From the picture, we can tell that your diamond has decent symmetry and a nice pattern.
It is an attractive diamond.
I only hope it is eye clean, I have no other concerns.
It should be full of fire.
