Is it normal for the clasp of a tennis bracelet to wiggle a little to where the diamonds looks a bit crooked? It is secure but every now and then I have to twist it straight. Here is a pic to show what I mean. Thanks in advance!!!
It shouldn't happen, but because most of these items are not really made to a high standard, the metal can fatigue and bend easier than one ought to hope for. If it stays connected, the clasp is still doing the job, but if the crooked look bothers you, the mechanism might be replaced with a bit stronger material which may be less prone to becoming offset. Your own level of activity and the frequency of wearing the bracelet also play a major role in how it will hold up over time.
Probably not. My clasp also didn't feel the most sturdy and looks very similar to yours so I had a catch chain soldered onto the bracelet just in case.
