How to tell if a diamond stud earring is real?

There are a few key things to look for when trying to determine if a diamond stud earring is real. First, check the setting of the earring. If the setting is made of gold or platinum, it is more likely that the diamond is real. Second, look at the clarity of the diamond. A real diamond should be nearly flawless, with no visible inclusions or blemishes. Finally, examine the cut of the diamond. A well-cut diamond will have crisp, clean angles and facets. If you see any imperfections in the cut, chances are the earring is not made with a real diamond.
