I am trying to come up with a decision between three stones engagement rings and need some help. She likes emerald cut diamonds and is more concerned with the overall look of a ring than the size of the center stone and I don't have an enormous budget so the center stone will probably be around 1/2 a carat or maybe a little more. It's pretty much a split decision between a three stone emerald or an emerald trillions combo. If it goes the three stone emerald way, I think I'd go with side stones that are a 1/3 of the size of the center stone, but if it goes the emerald cut trillion way I am a little unsure if that combo works with a modest center stone. Someone mentioned in another thread that trillion cut accents aren't the best choice when paired with center stones under a carat. Any thoughts on proportions and trillion cut accents would be helpful. In the end i think I'm looking for understated elegance. Oh yeah, she is on the petite side and has a 5.5 ring size.
