Dear fellow PS's, since I decided to take the next step in life a few months ago I've been lurking on this forum trying to soak in all the information I can about diamonds. Thanks to all of you guys I've learned a lot, but I'm still somewhat a newbie at this point. I've been working with a PS vendor who's been very helpful, and so far I've choosen 2 round brilliant diamonds for consideration. Both are the same color and clarity and almost the same carat weight and price. The specs from the GIA certificates are pasted below with some numbers from the Sarin report showing unrounded values:
Stone #1
GIA triple Excellent
Table: 56.5%
Total Depth: 61.1%
Crown Angle: 35.1
Pavilion Angle: 40.6
Crown Height: 15.4%
Pavilion Depth: 42.6%
Girdle: Thin to Medium
Star: 50%
LGF: 80%
Stone #2
GIA triple Excellent
Table: 57.7%
Total Depth: 61.0%
Crown Angle: 34.5
Pavilion Angle: 40.9
Crown Height: 14.6%
Pavilion Depth: 43.0%
Girdle: Medium
Star: 50%
LGF: 80%
The ASET images are attached below. They are taken on different dates so the camera setting may not exactly be the same. Both show some "paddling" or darkness at the arrow tips, with stone #1 looking more severe. What causes this, and how does it affect the performance of the stone? Which one would show more overall brilliance and fire? Stone #2 has a borderline-ideal 58% table, is that something I should be concerned about?
The vendor tells me that neither of these is a H&A stone, but as long as it sparkles like crazy I'm okay with it
Any and all opinions/critiques/nitpicks on each stone are much appreciated!
