I guess the official name of their species could simply be Gems, GAP probably thought they were the last uncorrupted Gems so they started calling themselves Crystal Gems to distinct themselves from others.

Yeah, that's what I'm thinking. That or crystal gems are a subsection of the overall species. GAP and Steven produce weapons from their gems, and that seems to be a natural occurrence. Lapis' gem doesn't produce a weapon, just wings. I wonder if there's meaning in that, that some gems are naturally prone to combat while others aren't.
