Sun Stone: Evolutions and Uses
Sun Stone is an evolution stone introduced after the original five stones. It is used by a selection of Grass and sun themed species rather than following one universal type rule.
The important thing with Sun Stone is to separate the item’s core effect from the place where you happen to obtain it. Shops, pickups, rewards and DLC areas change between games, but the reason you would use the item is much more stable. This guide focuses on that evergreen purpose, the best known examples and the mistakes that commonly waste the item.
Sun Stone: what it does

Sun Stone has a specific role in Pokémon progression rather than acting as a generic power boost. Sunkern into Sunflora and Gloom into Bellossom are early examples. Cottonee into Whimsicott, Petilil into Lilligant and Helioptile into Heliolisk are later uses in compatible games.
How to use this item
The practical use of Sun Stone is straightforward once the requirement is clear. Choose the item in the Bag and apply it to an eligible Pokémon. The evolution occurs immediately when the game supports that pairing.
Where to find it
The exact source for Sun Stone depends on the game. Pokémon titles commonly place important items in shops, reward pools, overworld pickups, battle facilities, raids, auctions or NPC rewards. A location from one region should never be assumed to apply to another game.
Common mistakes
The main mistake with Sun Stone is easy to avoid. Gloom has a split evolution, with this item leading to Bellossom while a Leaf Stone leads to Vileplume. Using one route removes the option to take the other route on that individual Pokémon.
When it is worth using
Sun Stone is worth using when it solves a clear problem immediately. This is a good item to keep in reserve when completing several generations of Pokédex entries because its compatible families are spread across different regions.
How it fits with other Pokémon items
Think of Sun Stone as one part of a wider progression system. Evolution items solve species requirements, while training items such as Mints, Ability Capsule, Exp. Candy and Power Items change how a Pokémon develops without necessarily changing its species.
That means Sun Stone is most useful when you already know the result you want. The item should be treated as part of a species, training or breeding plan rather than something to spend simply because it is sitting in the Bag.
Before using Sun Stone, save if the game allows it and double check the Pokémon, form and intended result. Many item effects are easy to understand but awkward to undo, especially when the item triggers an evolution or changes a training setup.
For that reason, this page does not pretend there is one permanent location for Sun Stone. When you are playing a specific title, use the in game map, item shops and current game specific guides to find the repeatable source available in that release.
Another mistake is using this item before checking whether the target already has another evolution, Ability, Nature, held item or training route you prefer. Pokémon often gives you multiple ways to build the same species, and the fastest option is not always the one that suits your collection.
For a living Pokédex or competitive collection, keeping at least one spare this item can also save time later. Items that look common during the story can become annoying when several different projects need them at once.
That distinction becomes useful once you start building Pokémon deliberately. Evolution, IVs, EVs, Nature, Ability, friendship and level are separate systems, so this item should be used for the job it actually controls rather than as a substitute for another mechanic.
For long-term collection planning, keep rare consumables separate from everyday healing items and note which Pokémon still need an evolution, training or breeding change. That makes it much easier to avoid spending a specialised item on a temporary team member.
For first party background on Pokémon items and training, see the official Pokémon guide. Availability can differ between games, but the official material is useful for seeing how these items fit into the broader progression systems.
