I love the stud thread, which helped me make my decision on the mount for the White Flash ACA diamond my wonderful hubby presented me for Christmas. It was intended to be a pendant. I was lucky to sell my Leo studs, three prong basket, 24 points each, which I truly enjoyed every day, to upgrade for another WF ACA. I decided on the 4 prong basket, screw back, and I love, love, love them. So sparkley. See my pics.
