What is the diameter of the second stone?

They both look like they will perform brilliantly. In which case, I would go with the one that has:

1.) fewer or no inclusions seen by the unaided eye;
2.) the one with the larger diameter (which will make it appear larger); and
3.) all other variables being equal (price, apparent size by diameter, visibility of inclusions), might as well take the D

the measurement for the second one is 6.87*6.91*4.27,
