I'm giving these three stars because they are worth the money.  The quality is NOT very good.  I am not sure they are actually sterling silver.  I have very sensitive ears and can only wear silver or gold metals in my ears.  All other metals will give me really nasty ear infections.  Well, after wearing these continuously, my ears started to get infected.  Also, the backs do not fit very well onto the studs; they are pretty loose.  One of the backs actually over stretched (which was new to me!) and no longer worked at all. I had to substitute a back from another earring.  Also, I think they look kind of cheap.  They definitely look dull and not as sparkly the longer you wear them.

I recently lost my pair (after about 5 months) and I don't mind in the least.  I will not repurchase.  However, if you're looking for a cheap pair of earrings that are "good enough" and if you don't have any type of metal sensitivities, these are worth buying.  The price is right!
