All my diamond earrings have screw back and they are easy to wear once you get hang of it and unlike the butterfly backs these will never get lost .Just see that it is properly fit close to your ears ,the back will never unscrew itself .
Unfortunately I have lost a screw back so I know for a fact they will occasionally unscrew themselves. Mine were very large so I had a little plastic disc in the back to keep them upright. I think that and the fact that I wore earmuffs also played a role in how it came unscrewed.
