What I mean is are the gems like Grass-Gem, Bug-Gem etc in USUM?
From Generation VI onward, only the Normal Gem is obtainable in the core series games. While the Fairy Gem was introduced in Generation VI, it has never been obtainable in any game; it has only ever appeared as unused game data.
Not all of them. Only the Normal Gem.

Hope I helped!
