I have had this ring a short time, its very pretty and the center stone is not so large as to look gaudy or fake on small hands-I wear a 4.5-5 in rings and have very tiny hands and it looks nice and not overwhleming. It does run a little big and wonder if I should have gotten a 4 instead of 5 since I am in between. I have a 1.1 carat diamond solitaire necklace, and when I wear it with the ring, you really could not tell which is "real" and whic is cz, even looking up close. Maybe a jeweler or the like could tell if they really scrutinized the ring, but for 33 bucks that doesn;t really matter to me.
I had another cz ring I spent a lot more for, it lasted for over 6 years  with everyday and still sparkles, unfortunately I did not realize cz is not as hard as a diamond, and it got a "ding" in it-I am interested to see how this will hold up and plan to edit this over time re:wear and tear. But for the price, I can't complain.
Edit: I ahve had this ring for 5 months now. It still looks really nice. I have found if the metal starts looking scratchy, using the connosiers dry disposable jewelry wipes is the best way to clean it much better than the silver polishing cloths. It makes it look like new. And letting it sit in some water mixed with plain Dawn dtergent will get the stones looking sparkly and fresh.
I have gotten tons of compliments, and no one has asked whether or not it is real.
Edit 2: Okay, I will admit I have stopped wearing it. As I mentioned I do have a real diamond and decided to have it put in a plain setting to wear with my plain yellow gold band. I really enjoyed the unique look of this ring for a while but then wanted something more simple and classic. Also, I noticed at the 6 month point the stone did seem to get cloudy and i was always cleaning it. Still, its a great value-I paid 200 dollars to have my diamond set in a scrapped setting, so for that I could have replaced this ring 6 times. I love cz but I would say if you want something to wear daily that will last a long time and do not like the expense and social/environmental issues with diamonds(which I totally get, I just happened to have one given to me)-I would suggest getting a moissanite stone set in 14k gold versus cz in silver or at the minimum cz set in a quality metal and be prepared to replace it at some point.
On the other hand, a large # of people I know who treated choosing or adding to, upgrading their engagement rings, etc as if it were a matter of national security no longer wear them a few years later. So again by that measure this is a great value. Or if you are just looking for a change from your usual set!
