UPDATE: Tried a few more times to attach the clutch-back to the post - no success. Had to return them.

I didn't expect these earrings to be such large stones. The box has a warning on top about how fragile the posts are.... we shall see. I was unable to get the clutch-back on to one of the earring posts and ran out of time trying. Will try to wear them another day and see how it goes. If you like really big CZs these are for you - but because of the size they are not believable.
