Engagement ring ideas

Does anyone have any suggestions on where to find nice men's engagement rings? My boyfriend and I have been talking about when we want to get engaged and whatnot and we agreed that we both want engagement rings for each other. I've done a couple initial online searches (we aren't planning on getting engaged for probably a couple years - that shit's expensive) and haven't quite found anything close to what I think he would like. Has anyone looked for something like this and found a reliably nice website? Or if anyone's familiar with Seattle, do you know of any local shops I should consider? I want to start looking now so I at least have an idea of what to save up for and where to go when I'm ready to buy. Thanks in advance!!
