I did Google it, a few times, and the Bulbapedia says that Espeon/Umbreon evolve from friendship or the shards (I already have a moon and sun stone and it doesn't have any effect on an Eevee).
Im new to the Pokemon series so yeah~ like I said I did Google but thanks. Maybe I'm just getting confused and the shards are from previous games so are still listed on the Bulbapedia? But I've not played any others so I wouldnt know D:
Shards have nothing to do with evolution. The only way to evolve an Eevee into Espeon and Umbreon is to level up with high friendship at Day/Night respectively
The shards that you are thinking of are the ones only available in Pokemon XD, I think because there is no day/night cycle in that game so you couldn't evolve them the normal way.
