Which stone?

[dq808]

I am a diamond novice considering 2 different stones. I was wondering what people thought about each and which they would recommend. Specifically, would Diamond B be noticibly larger than Diamond A, and/or would Diamond A be of noticibly better quality than Diamond B? Which do you think is a better value? Thanks for the advice!

Diamond A $11000
1.36 G VS1
Depth 61.6

Girdle Medium
Cutlet none

Crown Angle 35
Pavilion Angle 40.8

Diamond B $12000
1.53 G VS2
Depth 61.9
Table 57
Girdle Medium
Cutlet none
Polish Exc
Symm Exc

Yes, the size difference will be somewhat noticable. After thinking that I then took a look at the angles and my first thoughts were...hmmm...I am not sure about those angles. They are outside of the regions that I was willing to accept after my study, and so I went ahead and plugged it into the HCA just to make sure before I commented and it came back as 3goods with an HCA score of 4.4. I don't know what the other one scores but just looking at it I am sure it is under a 2.0 and probably closer to a 1. Given that, and my understanding of angles, I would not hesitate to completely walk past the second stone without ever thinking about it again.

That being said, I wonder if you hvae done enough research yet to really commit to one or two diamonds yet? I think you might want to read up a little more about cut, and about GIA excellent cuts, here on pricescope and various other places before making a commitment on such a significant purchase.

for an understanding of HCA scores go to the tools section located at the top of the page. Here is where I plugged in your numbers on stone 2HCA "thingy"

Welcome to PS. Also ditto WH4, with the info given, the first is the better cut. The second is what we call a steep deep with the crown and pavillion angles and it may look dark and leak light as a result, an Idealscope image would be useful to confirm, also it scored fairly dismally on the HCA, possibly aided by the steep pavillion angle. I would pass on the second diamond and see about an Idealscope image for the first if you want to learn more about this diamond.

Ditto that. I won''t want a bigger "dead" stone. Perhaps dropping to an eyeclean SI1 or SI2 and H colour (unless you''re colour sensitive like me!) will help you get a bigger ideal cut stone.
