Are these Diamonds at a good value, or not?

[DiamondDazzler]

I recently came across, http://ZooZource.Info/Shopping.html and found a few diamond stores and the prices seem really reasonable for some beautiful diamonds (rings, chains, etc.)

I am wondering if any of you have ever made purchases from either of those stores and if so, are they exactly as photographed, because if so there are a lot of jewels I would like to purchase. I could just get a few and simply return them if they aren''t what I am expecting, but before even attempting to buy anything, I am just wondering if anyone else has, thanks in advance.
