Thanks for the feedback everyone. I am not sure of who the designer of the ring is. I purchased it from a local jewelry store. The owner mentioned that he had the CAD drawings for it.
Here are the specs on the diamond. I looked at quite a few in person before making the decision. The one I purchased looked the closest to a true G color when comparing side by side with a 1.01 GIA G SI1.
