Yes, we would need all of the specs to compare.I’d prefer a better cut over color. Some people are more color sensitive than others. Unless we have all the specs to compare, we don’t really know which cut is better. IF the Tiffany diamond is of equal quality cut & includes the ring setting & service that accompanies it - the price difference becomes very slim in my opinion.
I wish more people would realize the most important "C" is cut, for it is truly what makes the diamond come alive and sparkle! I am color-sensitive too, so I settled for an E.
