Pokemon GO's collection of items that evolve Pokemon has steadily grown over the game's tenure, and this is no different for the Unova Stone.
Integral to evolving certain Pokemon from the Unova Region of the Pokemon: Black and White games, Unova Stones can be obtained via breakthroughs in research and by defeating Team GO Rocket Leaders.
Research breakthroughs can be achieved by finishing daily research tasks, earned by spinning the Pokestop discs.
Once seven research tasks have been completed and their stamps collected, Pokemon GO trainers will have a chance to earn a Unova Stone.
