Where can I find gems in x?

Question

I found a normal gem wondering if there is a cave to find more in x

I wanted this to be an answer, but it wouldn't be much anyway.
As PX said, the gems from Gen 5 are unavailable except for the Normal Gem. However, there is a Fairy Gem found in the game's data, however, it is still unavailable. It cannot be obtained legitimately in any Pokémon game and includes the new, Gen 8 games.

Answer 1

They are currently unavailable in X and Y versions. Sorry

Answer 2

You can't get any other gems other than Normal gen at the moment, sorry.

>unfortunately the normal gem is the only gem that has been released in gen 6 so far

Source: Neoseeker forum and I have searched for them too.

Hope this helps a bit.
