Potential companions for stud earrings or a balanced two-stone design, ranked by carat, face-up dimensions, color, clarity and finish.

What does "face-up variance" mean?

It is the average percentage difference in visible length and width when the diamonds are viewed from above. It describes apparent size, not depth, total carat weight or facet pattern. Lower is closer, and a matched pair is confirmed by comparing the two stones together.
