I have bought a lot of CZ's many for a lot more money than this one. They always look so sparkly at first. But my hands are constantly in water and soap and chemicals and they usually lose their luster with in a week or two, even with cleaning them. I bought the sterling silver and it arrived shiny and sparkly. After four weeks of wearing this ring every day, it has remained as nice as the day I received it. I am very impressed for the price. The silver actually has the look of white gold and has retained that look and the CZ looks like a diamond. Very nice size too, not overly big just right.
