Gosh I don't like her ring at all
I'm a fan of diamonds with square edges ( you know like baguette shapes, or emerald-cut and princess-cut stones, my own e-ring is a princess cut) but I think this one looks really gaudy and old-fashioned.
I often think that when I see GIANT ROCK engagement rings on celebrities (you know ones that take up the whole space between the knuckle on your hand and the first knuckle on your finger). I think big stones can be gorgeous (I have serious ring envy of one of my customers who has what looks like a 2 carat stone) but I think there's a point where they go from being classy-"wow" to tacky-"wow".
