I own a half carat round diamond solitaire from Zales. To be honest, I always loved the ring but wanted something a little bigger now that I'm in my 30's so I decided to purchase this ring. When I put it on and compared the two side by side on the same finger, there was absolutely no telling the real and the fake apart. This is a beautiful ring, the stone size is perfect and it is an exact replica of a real diamond. This is one of the best purchases I ever made. You will not be disappointed. The only person who could tell the difference between this ring and a real diamond would be a jeweler. It's fantastic!
