Before you visit any jewelry store in the mall, be sure to visit the independant jewelers around the area. One great example of this is Medawar Jewelers. They have locations around Lansing and in Jackson, I believe.
Their prices and quality actually beat the larger stores like Zales, JB Robinson, etc. I only wish that I would have visited this store before I purchased the diamond engagement ring for my wife a few years ago from Zales. Their service is horrible, Medawar, however, is excellent.
They have a huge selection and are always eager to help you choose the perfect item.
