Help me choose an engagement ring for her?

Hello everyone. I've been doing some shopping for an engagement ring for her. Ive got three styles that are similar but different in their own way. I'm pretty sure I'm going to go with platinum because of its durability and because it tends to be hard on things. In addition, from what I understand they do not have to be re-plated as white gold. I am interested in what everyone thinks!
