The angles aren't perfectly complementary, but the images suggest strong light return. They have me scratching my head though, because typically when I see a magnified image with those dark areas under the table (2 oclock, 4 oclock, and to a lesser degree 10 oclock) they correspond with areas of leakage on the IS and ASET. That isn't the case here though, and both the IS and ASET look good.

Hi there

There's also this stone here: 2.7 ish ct depth: 62 table: 56 crown angle: 35 pavillion angle: 40.8 LGF: 75%
Girdle: 3.5%.

Dimensions: 8.9 X 8.92 X 5.52

It doesn't face up that much more than the other stone, despite being .2 ct more.

I like the specs of this one better, but it's more expensive and you wouldn't be able to tell the size difference really.

Thanks so much for any help!

Thank you pfunk! Do you think the 2.5 stone will produce good fire? I understand you need a higher crown angle to achieve that.

Is the 34/40.6 numbers off a gia report?
In general that combo is fine but the gia rounding can mask minor issues, but unless it has wide ranging angles and too many of them drop below 40.5 they are generally fine.
Such a combo can have very nice fire.

It is obstruction, the diamond is way over obstructed in the picture, like looking at it from 2 inches.
The angles work well together, I didn't run it but the hca should give it a good score.

Thanks Karl_K!
Yea they are gia graded. The 2.5 ct scores 0.6 all excellent on HCA.

Is the obstruction a very bad thing?
Any thoughts on the second stone?

Thanks so much.

It can make the diamond look dark when viewed past arms length if it does not stop obstructing from a too shallow pavilion.

Its decent and no doubt pretty but not what a purest would consider a super ideal.
