The gem placement corresponds personality wise. Like lapis's gem is on her back because she is a constant prisoner. Or Jasper has hers on her nose because she is wild and savage. Gem placement has some effect since it corresponds to the gems emotionally. And it is supposed to be unique, as every gem is different in their own way. The design of the gem has no effect most of the time, though.
