Good experience with the ring.
I finally purchased on this website because the prices were reasonable and they had what I liked. I was able to select the center stone to an inexpensive 1 carat round diamond. It arrived shortly after placing the order. The stone is just about eye clean (I1) and bright just like I hoped for. The set has small diamonds and they look much better than the 1ct, and they said if I want to trade out the center I could do it anytime. They were nice.
