Choose what looks best on you and what is comfortable. Jewelry such as pearls and diamonds are VERY common and if you feel that it completes your outfit there's no harm in it. FWIW it might be best to just have a signature piece of jewelry such as your pearl necklace throughout the process to avoid to the potential backlash of trying to "dress" for a sorority. As long as you aren't wearing accessories that are significant to a particular sorority (i.e. lyres or anchors) you shouldn't have much to worry about.
