These studs were exactly what I was looking for, not too small and not too big.  They fit perfectly in the groove on my ear.  I especially love the silicon covered pushbacks!  I was worried they would be regular sized, but they too are sized perfectly!  You can't see them at all from the front!  They have stayed in place at night and in the shower.  I need to find replacement pushbacks this style and size for all my earrings!  Most importantly, I took the time to check to see if the earrings were engraved.  Real gold is suppose to have the karat weight engraved on it and sure enough, in little tiny print on the stem is "10K G"!  I am very happy with the purchase and bought another pair!
