I ordered these earrings as a Christmas gift for my sister.  I wanted an earring that could be worn with most any outfit, and these definitely fit the bill.  They can be dressed up, or worn casually.  My sister prefers leverbacks as they are more secure and easy to get in.  These appear to be good quality, and easily worth the $15 I paid.  They also catch the light very well.

The Amazon product image gives these a sligh bluish cast, but they are clear.  Please see my picture of the actual earrings I received.  These are so nice, I'm tempted to get a pair for myself!
