They are 0.35ct each... grade is SI. According to Wink, one even has pretty good H&A. Color is "medium true blue".
Yes, they are IMPOSSIBLE (for me) to photograph. Despite repeated attempts. The stones look horrible in photo's (which is bad for websites selling them), but in person they are amazing !
The ring is REALLY nice as far as light return goes.
In sunlight the ring just "washes out" ... the center stone (H&A) reflects so much light, that it goes white..... but the blue diamonds shine.
In low light, it sparkles like crazy though. You can see it sparkle in starlight when it's too dark to see your fingers !
And, of course she said yes....
