This store truly is a diamond in the rough. They have 2 locations, one in Saint Charles, and one in Naperville. Their main focus is to provide quality diamonds. They offer very high end loose diamonds as well as a few settings. They have any kind of diamond you are looking for. If they don't have it, they make every effort to get it for you. Their prices are significantly lower than a retail chain with much higher quality. The diamond we bought from there was apparaised at 16K from Helsburg. We didn't pay nearly that much for it!
