Which looks better in the ear?

The lab-grown pair. D color and VVS1 clarity beat near-colorless I1 stones, and I1 inclusions can be seen at 4 mm without magnification.

Is the Blue Nile pair worth the extra money?

Only if you want natural diamonds. You pay $1,090 versus $265 for lower color and clarity grades, so the premium buys origin and brand, not sparkle.

Which holds value better?

The Blue Nile pair. Natural diamonds keep some resale value; lab-grown stones typically resell for a small fraction of their price.

Are the backs secure on both?

Both are secure. Blue Nile uses double-notched friction posts; the lab-grown pair offers screw-back, push-back or guardian-back options.

Are they the same size?

Yes. Both are 1/2 ct tw, about 1/4 carat per earring. The lab-grown stones are listed at roughly 4.0 mm each.

Can I wear either every day?

Yes. Both are 14k gold four-prong studs meant for daily wear. The lab-grown pair's screw-back option is the safer pick if you are active.
