My own engagement ring has a 1.25 carat Ascher diamond in a thin pave-diamond setting. I think it's a look that is both classy and timeless. As far as settings are concerned with an Ascher, I don't think you can go wrong with a pave, channel or cathedral setting. In my opinion, I think these settings best compliment the contours of the stone. Go to my website and click on one of the links for Blue Nile (this is the website where my husband purchased my ring from). You can play around on Blue Nile with how all different types of settings will look with an Ascher diamond. It's a lot of fun (or at least for most women) and will give you an idea of what you like and don't like
