i have a three stone oval ering. it was difficult trying to find the right matching wedding ring b/c of the length of the middle diamond (kinda overlaps into the space where the wedding band should be, if you know what i mean).
i have both a prong half circle circle diamonds eternity band, and a channel set half circle square diamond band. the prong has bigger diamonds. they're both nice, but each changes the look of the ering.
the prong adds a lot of bling, while the channel is understated but truly elegant. so it depends where i go as to which wedding band i'll wear. but between the two, the channel tiffany band is my favorite.
