Partially Yes. You can only buy 2 Mega-Stones, which are the ones of the two remaining starters you did not choose in the prof’s lab. They cost between 10,000 and 1,000,000 Pokédollar*, and they are located in the Stone Emporium, in Vernal Avenue, in Lumiose City.

Hope this helps.

You can only buy 3(technically 4)and that is from the older man left of the counter in the Stone Emporium in Luminose City.

The four you can buy are the Blastoisinite, Charizardite X, Charizardite Y, and Venasaurite.You get Charizardite X in Pokemon X, and Charizardite Y in Pokemon Y

He will give you the Mega Stones of the starter Pokemon youdidn’t pick,so you cannot have two Venasaurites without trading or cheating.

They cost as high as 1,000,000 Poke and as low as 10,000 Poke, depending on your style.

You get all the others as gifts, or on the ground using the Upgraded Mega Ring.

Yes, but only three of them. The man in the Stone Emporium in Lumiose City will give you the Mega Stones of the starter Pokemon you didn’t choose from the professor. So if I got Squirtle, the man would offer the Venusaurite and the Charizardite X & Y.

He will charge 1,000,000 to 10,000 PokeDollars each depending on your style, and you can only buy one per day.
