Translations:Gems/4/en

Note: Gyms yield 5 Gems per Pokémon, but not every pokemon in a gym will be the appropriate type. The most efficient gyms yield the most Gems per gym clear. (e.g. Violet City Gym is less efficient than the Petalburg City Gym because it takes twice as many clears of the Violet City Gym to obtain the same number of Gems).
