These studs are .428 each (.856TCW) -- they average about 4.85 diameter and are G/H, SI1. The settings are 8 prong martinis. I am perfectly satisfied with these earrings, actually more than satisfied -- they are pretty perfect. What I do not like are my ears. I would like to have larger diameter diamonds but am concerned that there would be not any margin of earlobe below the diamond and they would not look right on my ears. (I guess I could go just a fraction of a millimeter bigger, but it would hardly be worth it . . . .) What would you do? (if you had my bizarre little earlobes and these earrings . . . .)
