In the bright light it alternates between looking bright white and having a slightly luminous blue tinged glow. I'm not sold on the glow but I don't know that anyone who doesn't know about fluorescence would even notice it.I'm with SimoneDi on waiting as well... I'm sorry you don't love your new diamond.
BGD tends to do a black friday deal- given the tint is not obvious and you've just upgraded it, I'd say hang onto it for the next 2 months till after your wedding, then have everything ready to go when that deal goes live. Enjoy this ring for a little while firstSometimes you need time to learn how your stone behaves!
I'm curious though- how do you like the stone with fluoro in bright aussie sunlight? does it bother you? I remember you were a bit hesitant about it at first
