The Pokémart is the place where a player can buy various items for use in-game. They currently sell Evolution Stones.
Evolution Stones
An Evolution Stone is a powerful object which can trigger an evolution in certain Pokemon. The evolved form will be stronger than its previous form but will learn attacks at a later level. A Pokemon that evolves with a stone can evolve at any level. Stones currently cost 10,000 pokedollars.
