I have been looking for a pair of CZ studs for a long time, only finding ones that are too big, and so they look so "fake" when wearing them.  I am a medium-size woman, so this size of stud, 5mm is perfect on me.  I have small ears and very small earlobes and they work well for me.  The CZ's are very, very nice. The setting is a nice, simple, 4-prong setting.  This is why they could pass for real diamonds, because of the sparkle, the simple, classic setting, and the smaller stone size. They do sparkle very nicely! The clasps are nice and tight so you don't feel you will lose the earrings.  The setting is sterling silver.  For me, these are all-occasion earrings, I can wear them with jeans and a t-shirt, to work, or with a dress to a dressy event. They are an oustanding value for a beautiful little pair of studs.
