I would have to go for this in platinum

BUT with a nice,saturated,custom cut aquamarine.I would have loved to have the aqua from my promise ring recut to be antique-like (it's an oval already),but it's on the smaller side and I'm afraid it would ends up too small..I also would love to get a very,very saturated,sky blue one in this ring,and mine is a paler,more delicate color.While I love it the way it is,I don't think it would contrast the setting enough.
