Anyone know where i can get eviolite?

for my delta Scyther

A man who sells competitive items including the eviolite is in the battle frontier. There is also one in the 2nd floor of the pokemon tower in the Void Gauntlet, it’s southwest of the stairs leading down to the first floor.

well thats pretty late into game, could someone buy me one and trade it to me?
