I have the white gold asha's in the martini setting. I got the 1ct tw and wish I had gotten the 1.5 carat tw. However, they are totally believable as most people I know would not spend that much on real diamonds! I ordered them from http://www.ashadiamonds.com/ because I could get them in screw backs, which I wanted. I think they look very real and I am very happy with them. I keep them in all the time. They arrived pretty quickly and in were wrapped really nicely. I may order the asha flanders next. They are the ones I wanted really badly, but they were only in 2 carat total weight. I was afraid they might be too much, but hey, life is short, so why not?
