These diamond stud earrings are tiny and with 12-13 clarity, they're kind of cloudy.  Not as sparkling as you would expect a diamond to be but then diamonds come in all sorts of degrees of clarity.  I like small stud earrings so they're right up my alley.  I've seen this size earring on guys and on people with several piercings on their bodies like in the nose for example.  As for the white gold setting, it seems sturdy.
